Unauthenticated Command Injection in ZyXEL P660HN-T1A ViewLog.asp Remote System Log
CVE-2017-18368 is a command injection vulnerability in the ZyXEL P660HN-T1A v1 router running TCLinux firmware $7.3.15.0 v001 / 3.40(ULM.0)b31, as distributed by TrueOnline. The flaw is present in the Remote System Log forwarding functionality exposed through the ViewLog.asp page.

The issue is explicitly described as reachable by an unauthenticated user.
