Message-ID: <20150629100539.GL13114@tortuga> Date: Mon, 29 Jun 2015 12:05:39 +0200 From: Oliver-Tobias Ripka <otr@...kcay.de> To: fulldisclosure@...lists.org Subject: [FD] CollabNet Subversion Edge weak password storage mechanism # Vuln Title: The CollabNet Subversion Edge stores passwords as unsalted MD5 hashes # Date: 28.06.2015 # Author: otr # Software Link: https://www.open.collab.net/downloads/svnedge # Vendor: CollabNet # Version: 4.0.11 # Tested on: Fedora Linux # Type: Insecure password storage # Risk: Medium # Status: public/fixed # Fixed version: 5.0 Timeline: 2014-10-09 Flaw Discovered 2014-10-20 Vendor contacted 2014-10-21 Vendor response 2014-12-08 Vendor fix proposal 2014-12-08 Extension of embargo to 19.4.2015 2015-05-04 Extension of embargo until release of version 5.0 2015-05-18 Release of version 5.0 and public disclosure Summary: The CollabNet Subversion Edge Management stores passwords as unsalted MD5 hashes. Unsalted MD5 hashes can easily be cracked by brute forcing the password. Fix proposal: Use a strong password storage algorithm like scrypt or PBKDF2. Vendor fix: We opted to go with bcrypt. It has more usage than scrypt and does not have any known vulnerabilities; it is also more easily supported with the subversion server, not just the Edge admin console. The strength factor is configurable. _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
