CVE-2026-25193 — Insertion of Sensitive Information into Log File in Gallagher Active Directory Sync

Insertion of Sensitive Information into Log File (CWE-532) in some Command Centre Service installers could lead to Service Account credentials exposure.  Mitigating Factor: Only sites that install Command Centre Services with a custom Service Account (not the default Network Service account) are potentially impacted. Mitigation: For sites concerned about exposure, the recommended action is to change the Service Account password. They can also delete any installer log files, usually found in %programdata%\Gallagher\Command Centre.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.1% (30-day exploitation probability)+0
Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Gallagher Active Directory Sync, Gallagher Cardholder Sync Utility, Gallagher Command Centre…).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.
Search available logs for exploit probes matching the vulnerability class (info disclosure), errors and authentication anomalies.
