CVE-2017-9736

Published: 17 June 2017

SPIP 3.1.x before 3.1.6 and 3.2.x before Beta 3 does not remove shell metacharacters from the host field, allowing a remote attacker to cause remote code execution.

Notes

AuthorNote
seth-arnold
The patches look like this is a simple black-list functionality
but doesn't black-list $() or `` or <() or any other number of shell
metacharacters. I expect this is still broken and should use a whitelist
of a-z0-9_-.
