Description

Multiple unrestricted file upload vulnerabilities in the (1) twikidraw (action/twikidraw.py) and (2) anywikidraw (action/anywikidraw.py) actions in MoinMoin before 1.9.6 allow remote authenticated users with write permissions to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in an unspecified directory, as exploited in the wild in July 2012.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for moin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update moin to 1.9.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2012-6081 is resolved across your whole dependency graph.

  3. Workarounds

    Treat uploaded files as untrusted until proven otherwise: validate the actual content type rather than the supplied extension, store uploads outside the web root on a volume mounted without execute permission, and rename them to server-generated identifiers so an attacker cannot choose the path a request will later resolve.
