CVE-2017-18026

HIGH 8.8EPSS 2.83%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.83%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Redmine before 3.2.9, 3.3.x before 3.3.6, and 3.4.x before 3.4.4 does not block the --config and --debugger flags to the Mercurial hg program, which allows remote attackers to execute arbitrary commands (through the Mercurial adapter) via vectors involving a branch whose name begins with a --config= or --debugger= substring, a related issue to CVE-2017-17536.
