How to Fix CVE-2024-42482

To remediate this vulnerability, upgrade all affected Fish shop/syntax check dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

fish-shop/syntax-check fixed: 1.6.12 
Upgrade fish-shop/syntax-check to 1.6.12
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for fish-shop/syntax-check

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-42482, inspect your project dependencies for Fish shop/syntax check:

inspect dependencies for fish-shop/syntax-check

Analyze the terminal output to locate any version of Fish shop/syntax check in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6.12), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-140: Improper Neutralization of Delimiters, where the product does not neutralize or incorrectly neutralizes delimiters. In Fish shop/syntax check, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Improper neutralisation of delimiters in the `pattern` input (specifically the command separator `;` and command substitution characters `(` and `)`) mean that arbitrary command injection is possible by modification of the input value used in a workflow. This has the potential for exposure or exfiltration of sensitive information from the workflow runner, such as might be achieved by sending environment variables to an external entity. ### Patches As of this writing, the issue has been patched for versions in the `v1.x.x` release series in release `v1.6.12` (also tagged as `v1.6` and `v1`). The latest available release `v2.0.0` also includes a corresponding patch (also tagged as `v2.0` and `v2`). Users should upgrade to at least the patched version `v1.6.12` or preferably the latest available version `v2.0.0`. Workflows that use the action ref `v1` will automatically receive the patched version `v1.6.12` in future workflow runs. Patch summary: | Release series | Patched tags | Patched commit hashes | |----------------|-------------------------|-------------| | `1.x.x` | `v1.6.12`, `v1.6`, `v1` | `91e6817c48ad475542fe4e78139029b036a53b03` | | `2.x.x` | `v2.0.0`, `v2.0`, `v2` | `c2cb11395e21119ff8d6e7ea050430ee7d6f49ca` | ### Workarounds Is it recommended that users update to the patched version `v1.6.12` or the latest release version `v2.0.0`, however remediation may be possible through careful control of workflows and the `pattern` input value used by this action. ### References - [CWE-140: Improper Neutralization of Delimiters](https://cwe.mitre.org/data/definitions/140.html) - [CAPEC-15: Command Delimiters](https://capec.mitre.org/data/definitions/15.html)
