Date: Mon, 29 Jun 2015 12:04:25 +0200 From: Oliver-Tobias Ripka <otr@...kcay.de> To: fulldisclosure@...lists.org Subject: [FD] CollabNet Subversion Edge insecure password change # Vuln Title: The CollabNet Subversion Edge management frontend does not require # current password upon password change # # 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 change # 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 management frontend does not require the old password for changing the password to a new one. An authenticated attacker may perform password setting attacks via XSRF without knowing the current password. An attacker that stole a Session ID (cookie) is able to gain persistent access by changing the password. Fix proposal: A password change should require the old password to be provided. Vendor fix: When a user is changing their password, they are now required to enter their current password. _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
