Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Duplicate Advisory, 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

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-gwfr-jfjf-92vv. This link is maintained to preserve external references. ### Original Description A vulnerability was found in Grav CMS up to 1.7.49.5/2.0.0-beta.1. Affected by this vulnerability is the function FileCache::doGet of the file system/src/Grav/Framework/Cache/Adapter/FileCache.php of the component Cache Value Handler. The manipulation results in deserialization. The attack may be launched remotely. The attack requires a high level of complexity. The exploitation appears to be difficult. The exploit has been made public and could be used. Upgrading to version 2.0.0-beta.2 addresses this issue. The patch is identified as c66dfeb5f. The affected component should be upgraded.
