Date: Wed, 14 May 2014 09:39:05 +0300 From: Dolev Farhi <dolevf87@...il.com> To: fulldisclosure@...lists.org Subject: [FD] Cobbler Arbitrary File Read CVE-2014-3225 Vulnerability title: Arbitrary file read 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. https://github.com/cobbler/cobbler/issues/939 -------------------- Proof of concept -------------------- 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. ------------------------------ PROOF OF CONCEPT vid ------------------------------ https://www.youtube.com/watch?v=vuBaoQUFEYQ _______________________________________________ Sent through the Full Disclosure mailing list http://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
