The remote host is running a version of MaxWebPortal that is prone to multiple input validation vulnerabilities:
Multiple SQL Injection Vulnerabilities An attacker can inject SQL statements via various scripts to manipulate database queries.
A Cross-Site Scripting Vulnerability An attacker can pass arbitrary HTML and script code via the ‘banner’ parameter of the ‘links_add_form.asp’ script to be executed by a user’s browser in the context of the affected website whenever he views the malicious link.
