Title: DeleGate Cross-Site Scripting Vulnerability
Severity: HIGH
Description:
DeleGate is a proxy server which runs on Linux , Unix, Microsoft Windows and OS/2 platforms. It is capable of translating a number of protocols(HTTP, FTP, NNTP, POP, Telnet, etc.) between client and server.
DeleGate is prone to cross-site scripting attacks.
HTML tags are not filtered from links to error pages. For example, a page that displays a 403 error message or a custom error page created by the administrator and displayed using DeleGate's MOUNT option.
As a result, it is possible for an attacker to insert malicious script code into a link to a site running DeleGate. When a web user clicks the link an error page will be displayed and the script code will be executed on the web user in the context of the site running DeleGate.
Such an attack may be used to steal a legitimate user's cookie-based authentication credentials.
Affected Products:
- DeleGate DeleGate 7.7.0 .0
- DeleGate DeleGate 7.7.1
