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 · unedited
UnixWare dos7utils allows a local user to gain root privileges by using the STATICMERGE environmental variable to find a script which it executes.

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 confidence

In UnixWare 7, the dosutils package contains a vulnerability where the STATICMERGE environment variable can be manipulated to specify an alternate path for a script that gets executed with elevated privileges, allowing a local unprivileged user to gain root access.

MitigationApply any available vendor patches for UnixWare 7 dosutils; if patches are unavailable, disable or remove the dosutils package, or restrict execution permissions to prevent unprivileged user access.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the UnixWare version
    Run 'uname -a' or check /etc/os-release to confirm the exact UnixWare version. The vulnerability affects only UnixWare 7.1.
    Affected if The system is running UnixWare 7.1 exactly
  2. Check if dosutils package is installed
    Run 'pkginfo -l dosutils' or 'rpm -qa | grep dosutils' to list installed dosutils package files. Alternatively, check for common dosutils binaries like 'dosdir' or 'dosformat' in /usr/bin or /usr/sbin.
    Affected if The dosutils package is installed on the system
  3. Verify dosutils is executable by unprivileged users
    Run 'ls -la /usr/bin/dos*' or 'ls -la /usr/sbin/dos*' to check permissions. Also test running a dosutils command as a non-root user: 'su - nonrootuser -c "which dosdir"'.
    Affected if Dosutils binaries are accessible and executable by unprivileged (non-root) users
  4. Examine dosutils scripts for STATICMERGE usage
    Inspect dosutils scripts for references to STATICMERGE environment variable, typically found in /usr/lib/dosutils or within the package scripts. Use 'grep -r STATICMERGE /usr/lib/dosutils' or within the package directory.
    Affected if Scripts reference STATICMERGE environment variable without sanitization, allowing path manipulation

The system is affected if it runs UnixWare 7.1 with the dosutils package installed and executable by unprivileged users, where the STATICMERGE variable can be manipulated to control script execution paths.
