CVE-2017-5638
Description
The Jakarta Multipart parser in Apache Struts 2 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1 has incorrect exception handling and error-message generation during file-upload attempts, which allows remote attackers to execute arbitrary commands via a crafted Content-Type, Content-Disposition, or Content-Length HTTP header, as exploited in the wild in March 2017 with a Content-Type header containing a #cmd= string.
MergeBase Comment

The famous Struts CVE! It's not every day that an open source library leads to a 96 page congressional report!

We suspect more than a few cyber security startups launched in the wake of this incredible bug - and MergeBase is one of them.

The bug itself is incredible - a work of true genius - and we encourage all software engineers to study it (especially those comfortable with Java). The contortions required by the first attacker to exploit this are unbelievable, but the payoff was devastating: full remote-code-execution.
