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
Format string vulnerability in /bin/ftp in UNICOS 9.0.2.2 allows local users to have an unknown impact via format string specifiers in the quote command. NOTE: because the program is not setuid and not normally called from remote programs, there may not be a typical attack vector for the issue that crosses privilege boundaries. Therefore this may not be a vulnerability.

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

Format string vulnerability in the /bin/ftp binary on UNICOS 9.0.2.2 allows local users to inject format string specifiers through the quote command, potentially allowing memory read/write via format functions. The vulnerability requires local access and the binary is not setuid, limiting the practical exploitability for privilege escalation.

MitigationSince the ftp binary is not setuid and requires local access, primary mitigation is restricting local shell access. If a fix is required, the ftp client source code would need modification to sanitize input passed to format functions in the quote command handler.

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 operating system version
    Run the command to display the UNICOS version and revision (commonly 'uname -a' or 'vers' depending on UNICOS release)
    Affected if The system is running Cray UNICOS version 9.0.2.2 exactly
  2. Locate the ftp binary
    Verify the presence of /bin/ftp using 'ls -la /bin/ftp' or equivalent file system query
    Affected if The /bin/ftp binary exists on the system
  3. Check ftp binary permissions
    Run 'ls -la /bin/ftp' to inspect file permissions, specifically looking for the setuid bit
    Affected if The binary has setuid permissions (the vulnerability is more severe if setuid, but even without it local users can exploit the format string flaw)
  4. Test quote command behavior (optional for confirmation)
    Access the ftp client locally and use the 'quote' command with arbitrary input to observe how the application handles the argument
    Affected if The ftp client processes format string specifiers through the quote command without sanitization

A system is affected if it runs Cray UNICOS version 9.0.2.2 and contains the /bin/ftp binary with the vulnerable quote command handler.
