Exploitbox: WordPress Unauthorized Password Reset Vulnerability
May 05, 2017 @ 11:14:48

On the DotDev.co site Eric Barnes has written up a post talking about a recently announced vulnerability (and 0-day exploit) for WordPress allowing for password reset emails to be delivered to a user-specified address instead of the correct one on the account:

On the Exploitbox site Dawid Golunski shares a 0 day vulnerability in the WordPress core affecting all versions:

The vulnerability stems from WordPress using untrusted data by default when creating a password reset e-mail that is supposed to be delivered only to the e-mail associated with the owner’s account.

The post includes a snippet of code from the WordPress core where the issue lies, relying on the value from PHP's $_SERVER['SERVER_NAME'] variable for the domain in the address the reset email is sent to. Unfortunately this value is pulled from the Host header in the request and is user-controllable. There's a solution offered using an Apache setting and it's noted that this exploit only seems to work against the default VirtualHost as it will act as a fallback if the Host does not reference a configured domain.

Month of PHP Bugs
Feb 07, 2007 @ 07:43:00

Ilia Alshanetsky posts today about the proposed "Month of PHP bugs" that Stefan Esser is proposing:

It would be interesting to see what issues he discovers, hopefully most of them have already been reported to the PHP Security Team, in which case the upcoming 5.2.1 release will provide a resolution path for affected users.

Hopefully, as Ilia states, the bugs will not turn out to be zero-day vulnerabilities and will instead be smaller issues. Either way, a bug-fix patch will probably soon follow.

Either way, I have to look at this as a free security audit of PHP by someone with a clue about security and ultimately, in the long run it will only make PHP better, even if March is going to be rather busy.
