CVE-2017-17459
http_transport.c in Fossil before 2.4, when the SSH sync protocol is used, allows user-assisted remote attackers to execute arbitrary commands via an ssh URL with an initial dash character in the hostname, a related issue to CVE-2017-9800,…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.80%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
