Report-Timeline: ================ 2012-04-26: Public or Non-Public Disclosure Status: ======== Published Exploitation-Technique: ======================= Remote Severity: ========= Medium Details: ======== Multiple persistent input validation vulnerabilities are detected in the Croogo v1.3.4 Content Management System. The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) context manipulation. Exploitation requires low user inter action. Attackers can inject malicious strings as username to execute them when a admin is processing to view, review or list username or names. The bug is located on application side & the execution is persistent out of the web application context. Vulnerable Module(s): [+] User Listing - Username & Name [+] Role Listing - Name & Alias Picture(s): ../1.png ../2.png ../3.png Proof of Concept: ================= The vulnerability can be exploited by remote attackers with low required user inter action.
