Detailsinfo

A vulnerability was found in LiuOS up to 0.1.0. It has been rated as critical. Affected by this issue is an unknown code of the component Environment Variable Handler. The manipulation of the argument GITHUB_ACTIONS with an unknown input leads to a authorization vulnerability. Using CWE to declare the problem leads to CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. Impacted is confidentiality, integrity, and availability. CVE summarizes:

LiuOS is a small Python project meant to imitate the functions of a regular operating system. Version 0.1.0 and prior of LiuOS allow an attacker to set the GITHUB_ACTIONS environment variable to anything other than null or true and skip authentication checks. This issue is patched in the latest commit (c658b4f3e57258acf5f6207a90c2f2169698ae22) by requiring the var to be set to true, causing a test script to run instead of being able to login. A potential workaround is to check for the GITHUB_ACTIONS environment variable and set it to "" (no quotes) to null the variable and force credential checks.

The weakness was disclosed 12/28/2022 as GHSA-f9x3-mj2r-cqmf. The advisory is available at github.com. This vulnerability is handled as CVE-2022-46179 since 11/28/2022. Technical details are known, but there is no available exploit.

Applying the patch c658b4f3e57258acf5f6207a90c2f2169698ae22 is able to eliminate this problem. The bugfix is ready for download at github.com.
