Advisory Details:
High-Tech Bridge SA Security Research Lab has discovered vulnerability in Collabtive, which can be exploited to gain complete control over the application. 1) Improper Access Control in Collabtive: CVE-2013-5027 The vulnerability exists due to improper access restrictions to the third installation step after successfully installing the application. A remote attacker can send a specially crafted HTTP POST request to the "/install.php" script and create a new user with administrative privileges.
