CVE-2011-4449: n/a vulnerability

CVE-2011-4449: actions/files/files.php in WikkaWiki 1.3.1 and 1.3.2, when INTRANET_MODE is enabled, supports file uploads...

actions/files/files.php in WikkaWiki 1.3.1 and 1.3.2, when INTRANET_MODE is enabled, supports file uploads for file extensions that are typically absent from an Apache HTTP Server TypesConfig file, which makes it easier for remote attackers to execute arbitrary PHP code by placing this code in a file whose name has multiple extensions, as demonstrated by a (1) .mm or (2) .vpp file.

Security readout for executives and security teams

This issue affects WikkaWiki 1.3.1 and 1.3.2 only when INTRANET_MODE is enabled. The upload feature can allow files with uncommon extensions that may still contain PHP code, creating a path to server-side code execution if the web server handles the file unsafely. Exposure is likely limited to legacy WikkaWiki 1.3.1 or 1.3.2 deployments with INTRANET_MODE enabled and web-accessible file uploads. Internet-facing instances are more urgent, but intranet-only systems still matter if untrusted users can upload files. Treat this as high priority for any remaining legacy WikkaWiki deployment. The business risk is server compromise through an upload feature, but urgency depends on whether the old versions and INTRANET_MODE are actually present. Mitigation focus: Check WikkaWiki guidance, ticket 1097, and changeset 1822 for the intended fix.; Upgrade or apply the vendor change if running WikkaWiki 1.3.1 or 1.3.2.; Disable INTRANET_MODE or file uploads if they are not operationally required..
