CVE-2022-37186: 
Linux Debian vulnerability analysis and mitigation

CVE-2022-37186 affects LemonLDAP::NG versions before 2.0.15. The vulnerability was discovered in the session management functionality where some sessions are not properly deleted according to the timeoutActivity setting. This issue specifically occurs in multi-server environments when a session is manually removed before its scheduled automatic removal time (NVD).

The vulnerability has been assigned a CVSS v3.1 base score of 5.9 (Medium) with the vector string CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N. The issue is classified under CWE-613 (Insufficient Session Expiration). The technical problem occurs in multi-server deployments where session deletion operations are not properly synchronized across all servers, leading to inconsistent session states (NVD).

When exploited, this vulnerability can result in sessions remaining valid on handlers even after being destroyed on the portal. This could potentially lead to unauthorized access as sessions that should have been terminated remain active, effectively bypassing the intended session timeout mechanisms (Debian Security).

The vulnerability requires network access and high complexity to exploit, but no privileges or user interaction. The attack vector is network-based, and while the vulnerability has been publicly disclosed, there are no known reports of it being actively exploited in the wild (NVD).

The vulnerability has been fixed in LemonLDAP::NG version 2.0.15. Organizations using affected versions should upgrade to version 2.0.15 or later. Multiple Linux distributions have also released security updates to address this vulnerability, including Debian which has released version 2.0.2+ds-7+deb10u8 for Debian 10 (Debian Security).
