[原文]Cross-site scripting (XSS) vulnerability in index.php for Ledscripts.com LedForums Beta 1 allows remote attackers to inject arbitrary web script or HTML via the (1) top_message parameter or (2) topic field of a new thread.
It has been reported that LedForums is prone to a HTML injection vulnerability that may allow an attacker to execute HTML code in a user's browser. The issue is reported to be present in the 'top_message' and 'topic' fields. This problem is due to insufficient sanitization of user-supplied input.
Successful exploitation of this vulnerability may allow an attacker to steal cookie-based authentication credentials. Other attacks are also possible.
LedForums Beta 1 has been reported to be vulnerable to this issue.
LedForums contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the "top_message" variable upon submission to the index.php script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
