Check_MK Agent for Linux 1.2.3i < 1.2.5i3 Arbitrary File Disclosure

medium Nessus Plugin ID 101088

Language:

Synopsis

An IT monitoring application running on the remote host is affected by an arbitrary file disclosure vulnerability.

Description

The version of Check_MK running on the remote web server is 1.2.3i prior to 1.2.5i3. It is, therefore, affected by a flaw due to the /var/lib/check_mk_agent/job directory creating temporary files with insufficiently secure permissions. A local attacker can exploit this issue by creating a symbolic link in the directory so that it points to a file the attacker normally would not have access to (e.g., /etc/shadow). Since the agent expects output from jobs using the mk-job Tool in that directory, it will output the content of all files in the directory on TCP port 6556 by default.

Solution

Upgrade to Check_MK version 1.2.5i3 or later.
