CVE-2012-6495· NVD / CVE Program· CNA mitre

Multiple directory traversal vulnerabilities in the (1) twikidraw (action/twikidraw.py) and (2) anywikidraw (action/anywikidraw.py) actions

Multiple directory traversal 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 overwrite arbitrary files via unspecified vectors. NOTE: this can be leveraged with CVE-2012-6081 to execute arbitrary code.

    Root cause

    A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
