Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple directory traversal vulnerabilities in TikiWiki 126.96.36.199 and earlier allow remote attackers to include and execute arbitrary files via an absolute pathname in (1) error_handler_file and (2) local_php parameters to (a) tiki-index.php, or (3) encoded "..%2F" sequences in the imp_language parameter to tiki-imexport_languages.php.
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.
