Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in receiveshortmessage.jsp where message bodies are rendered without HTML encoding via the filterMessageBody property. The ToolsUtil.convertURL() function passes user-supplied message content through unchanged, and the JSP uses bean:write with filter="false" to output the message body directly to the HTML response. An authenticated attacker can send a short message containing script tags, which will execute in the recipient's browser when the message is opened.
