CVE-2021-29665
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 Security Verify Access 20.07 is vulnerable to a stack based buffer overflow, caused by improper bounds checking which could allow a local attacker to execute arbitrary code on the system with elevated privileges.
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 Security Verify Access 20.07 contains a stack-based buffer overflow vulnerability caused by improper bounds checking. This allows a local attacker to execute arbitrary code on the system with elevated privileges, potentially leading to complete system compromise.

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 Security Verify Access is installedLocate the IBM Security Verify Access installation directory or check system services for the Verify Access service using commands like 'ls', 'sc query', or 'systemctl status' depending on your operating systemAffected if The product is present on the system
-
Determine the installed versionRun the version check command for IBM Security Verify Access, typically found in the installation directory (commonly /opt/ibm/verifyaccess or C:\Program Files\IBM\Verify Access) using 'version', '-V', or checking a version fileAffected if The installed version is exactly 20.07
-
Confirm the vulnerable binary or componentSince no specific vulnerable component is documented in this CVE, check for any IBM Verify Access executables or libraries in the installation path that may contain the stack-based buffer overflow vulnerabilityAffected if The vulnerable binary exists in the installation and version equals 20.07
-
Identify running processes using the affected versionUse process monitoring tools (ps, top, Task Manager) to confirm IBM Security Verify Access processes are running on the systemAffected if Verify Access processes are active on version 20.07
A system is affected if IBM Security Verify Access version 20.07 is installed and running, as this CVE targets that specific version with a local stack-based buffer overflow requiring no specific feature to be enabled beyond the base product.
