DescriptionCVE.org

IBM Tivoli Monitoring 6.3.0.7 through 6.3.0.7 Service Pack 20 is vulnerable to a heap-based buffer overflow, caused by improper bounds checking. A remote attacker could overflow a buffer and execute arbitrary code on the system or cause the server to crash.

Executive ViewAI

Why It Matters

Organizations using IBM Tivoli Monitoring 6.3.0.7 through 6.3.0.7 Service Pack 20 face notable risk from CVE-2025-3354, a heap-based buffer overflow vulnerability rated CVSS 8.1. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. Organizations should apply vendor updates when available and consider compensating controls in the interim.

Business Impact: High
Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Enable ASLR and DEP where available; (2) Implement network segmentation; (3) Monitor for exploitation indicators.

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

A heap overflow occurs when a program writes data beyond the bounds of a buffer allocated in the heap memory region.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
