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
SquirrelMail 1.4.11 and 1.4.12, as distributed on sourceforge.net before 20071213, has been externally modified to create a Trojan Horse that introduces a PHP remote file inclusion vulnerability, which allows remote attackers to execute arbitrary code.

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 · high confidence

SquirrelMail versions 1.4.11 and 1.4.12 distributed via SourceForge before December 13, 2007 were trojanized by attackers. The downloaded packages contained a PHP remote file inclusion vulnerability that was externally introduced, allowing remote attackers to execute arbitrary code by including malicious remote files.

MitigationVerify any historical installations of SquirrelMail 1.4.11/1.4.12 were obtained after 20071213; replace with clean versions from trusted sources and audit for unauthorized include() or require() statements pointing to remote resources.

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 installed SquirrelMail version
    Locate the version file or index.php and read the version string (typically shows '1.4.11' or '1.4.12')
    Affected if Version is 1.4.11 or 1.4.12
  2. Determine source acquisition date
    Check file timestamps, download logs, or archive metadata for when the SquirrelMail package was obtained
    Affected if Package was downloaded before December 13, 2007 from the compromised SourceForge distribution
  3. Inspect PHP files for remote include statements
    Search all .php files for include(), require(), include_once(), or require_once() calls with http:// or https:// URLs as parameters
    Affected if Any PHP file contains remote URL includes pointing to external domains
  4. Check for suspicious encoded strings
    Search PHP source for base64_decode(), eval(), or similar code execution functions in combination with variable strings that appear obfuscated
    Affected if Suspicious encoded payloads or dynamic code execution patterns are found in PHP files

A user is affected if they have SquirrelMail version 1.4.11 or 1.4.12 that was obtained from SourceForge before December 13, 2007, or if their installation contains remote file inclusion code in PHP files.
