CVE-2017-18123
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.60%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
