I just patched the board with the security update recently released at IPS. This security fix fixes some exploits that have been brought up . Here is the official post:
Enjoy .This post outlines the steps required to update your IPB 2.0.x or IPB 2.1.x for this security update.
If you've downloaded IPB 2.1.6 since the time of this post, there is no need to update your installation as the main download has been updated.
It has come to our attention that Invision Power Board 2.0.x and Invision Power Board 2.1.x contains two areas where malicious code could be executed. One area requires moderator access and other other requires a carefully crafted POST or GET request. Even though we've not been successful in expoiting IPB 2.1.6 using these methods in our own trials, we felt it best to strengthen security in these areas.
This discovery is based on research from Gulftech.org, a leading security company, and as such has not had full public disclosure.
This security update has a full version number of: 21012.60516.s.
Please read our KB article on how to locate your full version number.
If you find any problems, please let me know and i will try to fix them immediately .
