From bug to exploit - Bakery SSO
Heine Mon, 2013/02/18 - 12:59
I recently evaluated the Bakery Single Sign-On System aka Bakery SSO aka Bakery on behalf of clients. This article describes how I moved from finding a small weakness in version 2.x-alpha-3 to an exploit.
If you haven't updated all your sites to Bakery 2.0-alpha4 (6.x, 7.x), go and do so now.

If you get bogus dates back from MSSQL, make sure PHP is compiled against the FreeTDS libary that's currently in use. If not, recompile PHP.
Explaining the Drupal < 7.16 Installer vulnerability

SA-CORE-2012-003 fixes an issue in the Drupal installer that enables an attacker to cause the site to use a different attacker-controlled database.
The installer vulnerability was found while preparing my DrupalJam presentation (NL) on security audits and reported via the (awesome!) SecuriTeam Secure Disclosure program. As promised on IRC & Reddit, here's some additional information on the root cause(s).
Bounties: What to do with a high impact Drupal vulnerability?
Heine Mon, 2012/06/11 - 10:31
The security landscape is changing. There's been on and off talk about bounties for security vulnerabilities and some firms already buy vulnerabilities (SecuriTeam, ZDI). This also causes me to re-evaluate the value of a vulnerability.
Suppose I've recently found an arbitrary code execution vulnerability that could very likely be exploited on a large fraction of 400K+ Drupal sites.
What do you think I should do with it?
For the comments: What's your opinion on a security vulnerability bounty program?
Update: I've reported the vulnerability via SecuriTeam. It has been fixed with the release of Drupal 7.16. See SA-CORE-2012-003 for details.
