Why, hello there.
it appears to be a result of a vulnerability - or at the very least
weakness - in the implementation of libcurl; in particular, weak randomness in generating the form boundary. Is the boundary value generation required to be cryptographically strong? It does not come as a requirement as far as I know. The application itself has to perform proper input sanitation on ALL of its inputs coming from outside. For some reason, it is always libraries that are blamed for application flaws. 2013/6/24 Sven Slootweg <admin () cryto net>
Ran across a new post on a blog I frequently visit: http://localhost.re/p/solusvm-whmcs-module-316-vulnerability It describes a privilege escalation vulnerability in the WHMCS module for SolusVM that basically lets you do anything, but if I'm reading it correctly, it appears to be a result of a vulnerability - or at the very least weakness - in the implementation of libcurl; in particular, weak randomness in generating the form boundary. Thoughts? Note: I'm not the author of this exploit (it's actually quite a bit beyond my capabilities), I just ran across it and decided to post here since it doesn't seem to be discussed anywhere. Just to avoid people making incorrect assumptions... again :) - Sven Slootweg _______________________________________________ Full-Disclosure - We believe in it.
