Vulnerability Assessment Details
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.
A remote attacker may execute arbitrary PHP (and thus probably system)
commands with the permissions of the user running the process serving
Disable remote access to the "bin" subdirectory of the DokuWiki
installation. Remove the directory if you don't use the scripts in
All DokuWiki users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/dokuwiki-20060309d"
