Technical Analysis
This vulnerability involves an authentication bypass in LACT on Linux due to Polkit authentication relying on UnixProcessSubject / Peer PID. This flaw allows an attacker to spoof authentication, bypassing intended security controls. The affected versions are LACT up to 0.10.0. The issue was fixed by commit d0478fe42c2219454e272f96b1cbd29ab37ee566. The CVSS v3.1 score is 7.0, indicating high severity with local attack vector, high attack complexity, low privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation of this vulnerability allows an attacker with local access and low privileges to bypass authentication mechanisms in LACT, potentially leading to full compromise of confidentiality, integrity, and availability of the affected system or service.
Mitigation Recommendations
A fix for this vulnerability is available and was introduced in the commit d0478fe42c2219454e272f96b1cbd29ab37ee566. Users should upgrade LACT to a version later than 0.10.0 to remediate this issue. Since this is not a cloud service, manual patching by updating the software is required.
