Vulnerability title: Insecure Sudo Configuration in Symmetricom s350i
|Reported by:||Mike Emery|
It was discovered that the sudo rules configured allowed root access without a password prompt.
- The nobody user (used by the web server) was able to run all commands as root without providing a password
- The USERS group (to which shell users are added) was able to run a limited number of commands as root without providing a password
In the latter case, the USERS group is granted access to both:
/bin/ln /usr/bin/*ifaces.pl /usr/bin/*daemons.pl /etc/init.d/*
The use of these commands combine to allow any user with a shell root access.
Where password prompting is not enabled there is a chance that an attacker could access a compromised program to gain further privileges. Alternatively, an unattended SSH session could be abused if physical access to a workstation was possible.
