Title: IPMenu Log File Symbolic Link Vulnerability
Severity: MODERATE
Description:
ipmenu is a terminal based interface for Netfilter, iptables and linux policy routing or traffic control. It is freely available for Unix and Unix variants.
It has been reported that ipmenu is affected by a symbolic link vulnerability. This issue is due to a design error that allows for the creation of temporary files in an insecure fashion, facilitating symbolic links attacks.
The problem presents itself when the application creates the 'ipmenu.log' file in the '/tmp/' directory. It would be possible for a malicious user to construct a symbolic link named after the offending log file, which would lead to the application overwriting the target of the link file with root privileges.
This issue may be leveraged to create a system wide denial of service condition. This issue may also be leveraged to escalate privileges on the affected system, although this is currently unverified.
