L-Soft LISTSERV 16.5 Reflected Cross-Site Scripting
The REPORT parameter used by the wa.exe component of LISTSERV 16.5 is vulnerable to reflected Cross-Site Scripting due to improper sanitization of user input. By closing the HTML tag after the z parameter (as shown below), JavaScript can be injected into the URL before the a parameter.
note versions prior to 16.5 may also be affected but have not been tested.
