Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple directory traversal vulnerabilities in the (1) twikidraw (action/twikidraw.py) and (2) anywikidraw (action/anywikidraw.py) actions in MoinMoin 1.9 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.
CWE-22 - Path Traversal
Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
