Published: 06 August 2025
Summary
CVE-2025-3354 is a high-severity Heap-based Buffer Overflow (CWE-122) vulnerability in Ibm Tivoli Monitoring. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 26.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2025-3354 is a heap-based buffer overflow vulnerability affecting IBM Tivoli Monitoring versions 6.3.0.7 through 6.3.0.7 Service Pack 20. The issue arises from improper bounds checking, as classified under CWE-122. It carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to potential impacts on confidentiality, integrity, and availability.
A remote attacker with network access could exploit this vulnerability without privileges or user interaction, though it requires high attack complexity. Successful exploitation might enable arbitrary code execution on the affected system or result in a server crash, leading to denial of service.
The IBM security advisory at https://www.ibm.com/support/pages/node/7241472 provides details on mitigation and patching recommendations for this vulnerability.
