How to Fix CVE-2023-5588

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

pleroma fixed: 2.5.3 
Upgrade pleroma to 2.5.3
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 pleroma

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-5588, inspect your project dependencies for Pleroma:

inspect dependencies for pleroma

Analyze the terminal output to locate any version of Pleroma in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.5.3), 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Pleroma, 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

A vulnerability was found in kphrx pleroma. It has been classified as problematic. This affects the function `Pleroma.Emoji.Pack` of the file `lib/pleroma/emoji/pack.ex`. The manipulation of the argument name leads to path traversal. The complexity of an attack is rather high. The exploitability is told to be difficult. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The patch is named 2c795094535537a8607cc0d3b7f076a609636f40. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-242187.
