[GLSA-200609-10] DokuWiki: Arbitrary command execution |
||
DokuWiki: Arbitrary command execution Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200609-10 (DokuWiki: Arbitrary command execution) "rgod" discovered that DokuWiki doesn't sanitize the X-FORWARDED-FOR HTTP header, permiting the injection of arbitrary contents - such as PHP commands - into a file. Additionally, the accessory scripts installed in the "bin" DokuWiki directory are vulnerable to directory traversal attacks, permiting to copy and execute the previously injected code. Impact A remote attacker may execute arbitrary PHP (and thus probably system) commands with the permissions of the user running the process serving DokuWiki pages. Workaround Disable remote access to the "bin" subdirectory of the DokuWiki installation. Remove the directory if you don't use the scripts in there.
