CVE-2017-18123 (opens in a new tab)How to fix?
Upgrade Debian:11 dokuwiki to version 0.0.20160626.a-2.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream dokuwiki package and not the dokuwiki package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
The call parameter of /lib/exe/ajax.php in DokuWiki through 2017-02-19e does not properly encode user input, which leads to a reflected file download vulnerability, and allows remote attackers to run arbitrary programs.
