luny has reported some vulnerabilities in V3 Chat Instant Messenger, which can be exploited by malicious users to conduct SQL injection attacks, script insertion attacks, and bypass certain security restrictions, and by malicious people to conduct cross-site scripting attacks and SQL injection attacks.
1) Input passed to the "id" parameter in mail/index.php and to the "membername" parameter in members/online.php is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
2) Input passed to the "login_id" parameter in members/is_online.php and to the "membername" parameter in members/profileview.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
3) Input passed to the "aboutme" and "hobbies" form field parameters when editing a user's profile is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when a malicious profile is viewed.
4) Due to insecure authentication and session management it is possible for an attacker with a valid account to manipulate other user's profiles or to perform actions with the identity of another user by changing the "membername" parameter in the URL.
Solution: #1 and #3 are reportedly fixed in the latest version (2006-06-23).
