CVE-2007-3942
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 · uneditedDirectory traversal vulnerability in index.php in Simple Machines Forum (SMF) 1.1.3 allows remote attackers to include local files via unspecified vectors related to the sourcedir parameter or the actionArray hash. NOTE: CVE and multiple third parties dispute this vulnerability because both sourcedir and actionArray are defined before use
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 · low confidenceClaimed directory traversal/file inclusion in SMF 1.1.3 index.php involving the sourcedir parameter and actionArray hash. However, the CVE and third parties dispute this vulnerability, noting that both parameters are defined before use, which would prevent typical PHP local file inclusion exploitation.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify SMF installation versionLocate the SMF installation directory and check the version. Common locations: look for 'index.php', 'Settings.php', or a 'version' file in the forum root directory. The version is often hardcoded in index.php or a version info file.Affected if The installed version is exactly 1.1.3
-
Verify index.php existsConfirm that index.php exists in the SMF web root directory.Affected if The index.php file from SMF 1.1.3 is present in the web-accessible directory
-
Examine sourcedir parameter handlingInspect the index.php file for how the 'sourcedir' parameter is processed. Look for the code section where sourcedir is defined or assigned before any include/require statements use it.Affected if The sourcedir parameter is defined and used in include/require statements in index.php (indicating potential LFI vector if improperly handled, though disputed)
-
Review actionArray hash implementationSearch the index.php file for 'actionArray' and verify how this array is constructed and used, particularly in relation to the 'action' parameter processing.Affected if The actionArray hash is used to map action parameters to files without proper validation (the disputed exploitation condition)
A user is affected only if they run SMF version 1.1.3 AND the index.php contains the disputed sourcedir/actionArray handling that could allow file inclusion when the parameters are manipulated, though the vulnerability validity is contested.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataGiven the dispute over this vulnerability's validity, verify the actual code behavior in the specific SMF version; if concerned, upgrade to a supported SMF release as 1.1.3 is legacy software.
