 CVE: CVE-2014-3225

 Vendor: Cobbler

 Product: Cobbler

 Affected version: <=2.6.0

 Fixed version: N/A

 Reported by: Dolev Farhi






----------------------------

VULNERABILITY Details:

----------------------------

In all Cobbler versions (<= 2.6.0) an arbitrary system files read
vulnerability is possible via the cobbler profile creation page.

Cobbler does not validate the file is a .ks file nor does it restrict the
user to a certain path.

Cobbler runs under the root user privileges, which allows read access to
all system files.

This issue exposes all files to any attacker attempting to provide full
file path to crucial system files such as /etc/passwd or /etc/shadow in the
Kickstart path.

Create a regular cobbler profile, assign a distribution to it.

In kickstart value, provide /etc/shadow or any other file.

Save -> navigate to “View kickstart” -> file is shown.
