Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Phpfastcache/phpfastcache, 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 An possible object injection has been discovered in cookie driver prior 5.0.13 versions (of 5.x releases). ### Patches The issue has been addressed by enforcing JSON conversion when deserializing ### Workarounds If you can't fix it, use another driver such as "Files" (Filesystem) ### References Fixing release: https://github.com/PHPSocialNetwork/phpfastcache/releases/tag/5.0.13 ### For more information If you have any questions or comments about this advisory: * Open an issue in [the issue tracker](https://github.com/PHPSocialNetwork/phpfastcache/issues) * Email us at [security@geolim4.com](mailto:security@geolim4.com)
