Other vectors for SA-CORE-2014-005?

Heine —Fri, 2014/10/31 - 21:57

This is intended a comment on Acquia's Learning from hackers a week after the Drupal SQL Injection announcement, but mollom prevents me from posting it there. In it, scor asks:

An open question is whether the SQL injection vulnerability was exploitable via some vector other than via the user login form.

Lazy loading: hook_hook_info is for hook owners only.

Heine —Tue, 2013/07/30 - 22:38

I've recently seen some recommendations to use hook_hook_info to provide "groups" to core-provided hooks so you can move your module's implementations of those hooks to $module.$group.inc. A poor-mans autoloader if you will.

Doing this can lead to unexpected results.

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.

Solving getting bogus dates via MSSQL_QUERY

Heine —Thu, 2012/11/29 - 19:24

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

Heine —Wed, 2012/10/24 - 11:24

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.
