CVE-2025-3320
Published: 06 August 2025
Summary
CVE-2025-3320 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-2025-3320 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, which allows a remote attacker to overflow a buffer. Published on 2025-08-06, 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) and is classified under CWE-122 (Heap-based Buffer Overflow).
A remote attacker can exploit this vulnerability without privileges or user interaction, though it requires high attack complexity. Successful exploitation enables arbitrary code execution on the system or causes the server to crash, resulting in high impacts to confidentiality, integrity, and availability.
