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
Sun PC NetLink 1.0 through 1.2 does not properly set the access control list (ACL) for files and directories that use symbolic links and have been restored from backup, which could allow local or remote attackers to bypass intended access restrictions.

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

Sun PC NetLink versions 1.0 through 1.2 fail to properly set Access Control Lists (ACLs) on files and directories that use symbolic links when they are restored from backup, potentially allowing attackers to bypass intended access restrictions.

MitigationReview and manually reset ACLs on all symbolic link files restored from backup, or migrate to a supported solution as Sun PC NetLink 1.x is obsolete (2002-era software).

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. Verify Sun PC NetLink installation
    Check for the presence of Sun PC NetLink software on the system. Look for package files or installed binaries related to PC NetLink, typically found in /opt or listed via the system package manager (pkginfo on Solaris).
    Affected if Sun PC NetLink is installed on the system
  2. Determine installed version
    Query the installed version of Sun PC NetLink using system commands such as pkginfo -l or by checking version strings in the binary (e.g., /opt/pcnl/bin/pcnlmd or similar). Compare the version number against the affected range 1.0 through 1.2.
    Affected if The installed version is 1.0, 1.1, 1.2, or any version within the 1.0-1.2 range
  3. Identify symbolic links restored from backup
    Review backup restoration logs or audit trails to identify if any symbolic links were included in recent or past backup restoration operations. Check for files/directories that are symbolic links in the restored data.
    Affected if Symbolic link files or directories were restored from a backup
  4. Inspect ACLs on restored symbolic links
    Use the Solaris ACL commands (getfacl or ls -ld) to examine the Access Control List settings on the symbolic link files that were restored from backup. Compare against expected ACLs or parent directory defaults.
    Affected if The ACLs on restored symbolic links are missing, incorrect, or differ from the intended access controls, indicating the vulnerability is present

The environment is affected if Sun PC NetLink version 1.0-1.2 is installed AND symbolic link files were restored from backup, resulting in improperly set ACLs on those links.
