Detailsinfo

A vulnerability, which was classified as problematic, was found in Matter up to 1.4.0.0. Affected is the function WriteAcl of the file access-control-server.cpp. The manipulation with an unknown input leads to a permissions vulnerability. CWE is classifying the issue as CWE-281. The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended. This is going to have an impact on availability. CVE summarizes:

In Matter (aka connectedhomeip or Project CHIP) through 1.4.0.0, the WriteAcl function deletes all existing ACL entries first, and then attempts to recreate them based on user input. If input validation fails during decoding, the process stops, and no entries are restored by access-control-server.cpp, i.e., a denial of service.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2024-56317 since 12/18/2024. The exploitability is told to be difficult. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1222.
