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
IBM AIX could 7.2, 7.3, VIOS 3.1, and VIOS 4.1 allow a non-privileged local user to exploit a vulnerability in the invscout command to execute arbitrary commands. IBM X-Force ID: 283985.

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

A local privilege escalation vulnerability exists in the invscout command on IBM AIX 7.2, 7.3 and VIOS 3.1, 4.1. A non-privileged local user can exploit this flaw to execute arbitrary commands with elevated privileges, likely through command injection or improper input validation within the invscout utility.

MitigationApply the IBM patch for APAR (if available) or update invscout to a patched version. Restrict local user access to the system and limit privileged command usage until the patch is applied.

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. Locate the invscout binary
    Run 'which invscout' or 'ls -la /usr/bin/invscout' to find if the invscout command exists on the system
    Affected if The invscout binary is present on the system; absence means not affected by this specific vulnerability
  2. Determine invscout version
    Run 'invscout -V' or 'invscout -version' to obtain the installed version number, then compare against the affected versions (AIX 7.2, 7.3 and VIOS 3.1, 4.1)
    Affected if The installed version matches AIX 7.2, 7.3 or VIOS 3.1, 4.1, or falls within the same version branch without a security patch applied
  3. Check invscout permissions
    Run 'ls -la' on the invscout binary path and look for 's' in the owner or group permission fields (setuid/setgid)
    Affected if The invscout binary has setuid or setgid permissions, which enables a non-privileged user to potentially leverage the flaw for privilege escalation
  4. Verify non-privileged user access
    Attempt to run invscout as a non-root user (e.g., 'su - nonrootuser -c "invscout"') or check file permissions on the binary
    Affected if Non-privileged users can execute invscout, creating the conditions for local privilege escalation
  5. Check for recent security patches
    Run 'invscout -V' and compare the full version string against IBM's published fixed versions, or check 'lslpp -l' output for invscout packages
    Affected if No IBM security patch (APAR) has been applied to the invscout installation, or the version remains unpatched

A system is affected if invscout is installed, runs with elevated privileges, and non-privileged users can execute it without having applied the IBM security patch for this CVE.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the IBM patch for APAR (if available) or update invscout to a patched version. Restrict local user access to the system and limit privileged command usage until the patch is applied.
