Control-M/Agent: Heap-based Buffer Overflow
CVE-2025-55118 is a high-severity heap-based buffer overflow vulnerability in Control-M/Agent from BMC, with a CVSS 3.1 base score of 8.9 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Control-M/Agent versions: 9.0.22.000; 9.0.21; 9.0.20, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.37% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Control-M/Agent you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| BMC | Control-M/Agent | 9.0.22.000; 9.0.21; 9.0.20; 9.0.19; 9.0.18 | Not stated |

Official description
Memory corruptions can be remotely triggered in the Control-M/Agent when SSL/TLS communication is configured. The issue occurs in the following cases: * Control-M/Agent 9.0.20: SSL/TLS configuration is set to the non-default setting "use_openssl=n"; * Control-M/Agent 9.0.21 and 9.0.22: Agent router configuration uses the non-default settings "JAVA_AR=N" and "use_openssl=n"

The underlying weakness: Heap-based Buffer Overflow
The product writes past the end of a buffer that was allocated on the heap.
How developers prevent this class of flaw
- Pre-design: Use a language or compiler that performs automatic bounds checking.
- Use an abstraction library to abstract away risky APIs. Not a complete solution.
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking. D3-SFCV (Stack Frame Canary Validation) from D3FEND discusses canary-based detection in detail.
