How to Fix CVE-2024-43791

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

request_store fixed: 1.4.0 
Upgrade request_store to 1.4.0
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 request_store

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-43791, inspect your project dependencies for Request store:

inspect dependencies for request_store

Analyze the terminal output to locate any version of Request store in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.0), 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-276: Incorrect Default Permissions, where during installation, installed file permissions are set to allow anyone to modify those files. In Request store, 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 The files published as part of request_store 1.3.2 have 0666 permissions, meaning that they are world-writable, which allows local users to execute arbitrary code. This version was published in 2017, and most production environments do not allow access for local users, so the chances of this being exploited are very low, given that the vast majority of users will have upgraded, and those that have not, if any, are not likely to be exposed. ### Patches I am not aware of any other version of the gem with incorrect permissions, so simply upgrading should fix the issue. ### Workarounds You could chmod the files yourself, I guess. ### References https://cwe.mitre.org/data/definitions/276.html
