Cross-site scripting (XSS) vulnerability in NetWin Surgemail before 4.3g allows remote attackers to inject arbitrary web script or HTML via the username_ex parameter to the surgeweb program.
NetWin (1) SurgeMail before 2.0c and (2) WebMail allow remote attackers to obtain sensitive information via HTTP requests that (a) specify the / URI, (b) specify the /scripts/ URI, or (c) specify a non-existent file, which reveal the path in an error message.
