CVE-2025-1095: IBM Personal Communications v14 and v15 include a Windows service that is vulnerable to local privilege escala

Routine

HIGH 8.8DOWNGRADE

CVE-2025-1095 is a high-severity flaw (CVSS 8.8) affecting personal communications. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

IBM Personal Communications v14 and v15 include a Windows service that is vulnerable to local privilege escalation (LPE). The vulnerability allows any interactively logged in users on the target computer to run commands with full privileges in the context of NT AUTHORITY\SYSTEM. This allows for a low privileged attacker to escalate their privileges. This vulnerability is due to an incomplete fix for CVE-2024-25029.
