CVE-2025-0164: 
IBM QRadar SIEM vulnerability analysis and mitigation

CVE-2025-0164 affects IBM QRadar SIEM versions 7.5 through 7.5 Update Pack 13 Independent Fix 01. The vulnerability was disclosed on September 14, 2025, and involves improper permission assignment that could allow local privileged users to perform unauthorized actions on configuration files. This security flaw is classified under CWE-732 (Incorrect Permission Assignment for Critical Resource) (IBM Advisory).

The vulnerability has been assigned a CVSS 3.1 base score of 2.3 (Low), with the following vector: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N. This indicates that exploitation requires local access and high privileges, with low complexity and no user interaction. The flaw affects confidentiality but does not impact integrity or availability (NVD, IBM Advisory).

The vulnerability allows local privileged users to access and modify configuration files without proper authorization. Such actions could potentially alter logging parameters, disable specific detection rules, or inject malicious parameters that evade standard security controls. While the flaw requires high privileges, it could be leveraged to weaken the security posture of the SIEM environment (GBHackers).

IBM has released QRadar 7.5.0 Update Pack 13 Independent Fix 02 (UP13 IF02) to address this vulnerability. The fix corrects file and directory permissions to restrict write access exclusively to the QRadar service account. No workarounds are available beyond applying the official fix. Organizations should restrict local administrative privileges to trusted personnel only and monitor filesystem changes in /opt/qradar/conf (IBM Advisory).
