improper pid file handling of webgui
Closed, ResolvedPublicBUG
Actions

Description

since the webgui is suid root, any unprivileged user (however they might get onto the system) might arbitrarily overwrite any file:

frr@fw0:~$ /usr/lib/cgi-bin-webgui -i /etc/resolv.conf
^C
frr@fw0:~$ cat /etc/resolv.conf
5947
frr@fw0:~$

don't know if that could be exploited to gain admin rights, but at least could hose the system.
