Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Backpack/filemanager, 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 Deserialization of untrusted data from the `mimes` parameter could lead to remote code execution. ### Patches Fixed in 3.0.9 ### Workarounds Not needed, a `composer update` will solve it in a non-breaking way. ### References Reported responsibly [Vladislav Gladkiy](https://github.com/catferq) at [Positive Technologies](https://www.ptsecurity.com/ww-en/).
