Incorrect Permission Assignment Flaw:
The vulnerability exists due to incorrect permission settings for crucial resources (CWE-732), which does not apply proper access controls on configuration files in QRadar SIEM versions 7.5 to 7.5.0 UP13 IF01.
A local user with high-level privileges can misuse poor file system permissions to change important settings, alter logging policies, or turn off detection rules.
Unauthorized changes may continue until manually fixed, complicating incident response and hiding malicious activities in logs, which could permit further undetected actions.
Mitigations:
IBM has released QRadar 7.5.0 UP13 IF02 to fix CVE-2025-0164, ensuring file and directory permissions only allow write access for the QRadar service account.
Administrators should apply the interim fix immediately on affected systems by downloading the update from IBM Fix Central.
