(Copy of the Vendor Homepage: http://www.squirrelcart.com ) Abstract: ========= Vulnerability Laboratory Research Team discovered multiple persistent web vulnerabilities in Squirrelcarts Shopping Content Management System v3.3.4. Report-Timeline: ================ 2012-06-04: Public or Non-Public Disclosure Status: ======== Published Exploitation-Technique: ======================= Remote Severity: ========= Medium Details: ======== Multiple persistent input validation vulnerabilities are detected in Squirrelcart Shopping v3.3.4 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 & privileged user account. The persistent vulnerabilities are located in the Discount Image > Document Edit Name module exception handling & the Location Hours of Operations day listing. When a customer includes the malicious script code to the profile configuration settings the code is getting executed out of the web application context when an administrator is processing to watch the listings. Vulnerable Module(s): [+] Group > Add Group or Customer > Detail > Image > Discount Image > Document Edit Name [+] Location > Warehouse > Listing > Hours of Operation Picture(s): ../1.png ../2.png Proof of Concept: ================= The persistent input validation vulnerabilities can be exploited by remote attacker or privileged user account with low required user inter action.
