CVE-2025-55113BMC Control-M/Agent unescaped NULL byte in access control list checks
Critical 9.0
In plain English
A critical-severity security flaw in Control-M/Agent from BMC. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 22% of all known vulnerabilities).
Official description
If the Access Control List is enforced by the Control-M/Agent and the C router is in use (default in Out-of-support Control-M/Agent versions 9.0.18 to 9.0.20 and potentially earlier unsupported versions; non-default but configurable using the JAVA_AR setting in newer versions), the verification stops at the first NULL byte encountered in the email address referenced in the client certificate. An attacker could bypass configured ACLs by using a specially crafted certificate.
