Teaming and conferencing offers a number of solutions to improve productivity for enterprises, with web conferencing just one of those solutions. [source: http://www.novell.com/products/teaming/] Vulnerability overview: ----------------------- Multiple vulnerabilities have been identified in Novell Teaming. These include enumeration of usernames, information disclosure, and cross site scripting flaws. An attacker could leverage these vulnerabilities to collect information about the system and its users and conduct effective (XSS supported) hybrid phishing attacks. Vulnerability description: ------------------------- 1. Username enumeration: User authentication takes place via a login form at: https://teaming.example.com/c/portal/login The web application reacts differently for valid and invalid usernames ("Please enter a valid login" / "Auhtentication failed"). This allows an attacker to deduce wether a spedific username exists. The attacker could use this flaw to generate a list of usernames for dictionary- or bruteforce-attacks. 2. Cross site scripting: The parameters p_p_state and p_p_mode are not validated or escaped by the web application. Script code can be injected into these parameters, allowing for cross site scripting attacks. Example: https://teaming.example.com/web/guest/home?p_p_id=82&p_p_action=1&p_p_st ate=%3Cscript%3Ealert('xss+vulnerability')%3C/script%3E&p_p_mode=view&p_ p_col_id=column-2&p_p_col_pos=1&p_p_col_count=2&_82_struts_action=%2Flan guage%2Fview&_82_languageId=de_DE 3.
