CVE-2025-3320
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIBM Tivoli Monitoring versions 6.3.0.7 through 6.3.0.7 Service Pack 20 contains a heap-based buffer overflow vulnerability caused by improper bounds checking. A remote, unauthenticated attacker can exploit this to overflow a heap buffer, potentially achieving arbitrary code execution on the affected system or causing a denial of service condition.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify IBM Tivoli Monitoring is installedCheck for the presence of IBM Tivoli Monitoring installation directory (typically under C:\Program Files\IBM\ITM or /opt/IBM/ITM on Unix) or query the Windows registry under HKEY_LOCAL_MACHINE\SOFTWARE\IBM\Tivoli\Monitoring or look for the itmcmd process/service.Affected if IBM Tivoli Monitoring software is found on the system
-
Identify the installed Tivoli Monitoring versionRun the version query command for your platform. On Windows, use 'itmcmd version -v' or check version info in the installation directory. On Unix/Linux, run './itmcmd version -v' from the installation bin directory. Alternatively, check the version file in the installation directory (commonly version.txt or install.inf).Affected if The base version reported is 6.3.0.7
-
Determine the Service Pack levelCheck the Service Pack level by running 'itmcmd query -p' or examining the patch level file in the installation directory (often named itm_sp.level or similar). On Windows, also check Add/Remove Programs for the installed Service Pack version string.Affected if The Service Pack level is 20 or lower (6.3.0.7 through 6.3.0.7 SP20)
-
Confirm the component vulnerable to heap overflowIBM Tivoli Monitoring heap-based buffer overflow typically affects the Tivoli Monitoring server or agent components handling network communications. Identify which components are running (ITM Server, TEPS, TEMS, or agents) using 'itmcmd agent -d' or the ITM Service Console.Affected if Tivoli Monitoring server or agent components are running and the version is within the affected range
The system is affected if IBM Tivoli Monitoring version 6.3.0.7 with any Service Pack level up to and including SP20 is installed and running.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-supplied patch or upgrade to a fixed version of IBM Tivoli Monitoring. If immediate patching is not possible, restrict network access to the monitoring interfaces and implement additional input validation at network boundaries.
