Title: PSCS VPOP3 Email Server WebAdmin Cross-Site Scripting Vulnerability

Severity: MODERATE

Description:

PSCS VPOP3 Email Server is an e-mail server and gateway.

A cross-site scripting vulnerability has been reported to exist in PSCS VPOP3.

The problem has been reported to exist in the WebAdmin utility of the software. The issue presents itself due to improper handling of user-supplied data in certain parameters, which will permit remote attackers to embed HTML and script code in links. HTML and script code could then be rendered in the browser of the user visiting the link. This attack would occur in the security context of the vulnerable site.

Successful exploitation of this attack may allow an attacker to steal cookie-based authentication information. Since the issue affects the WebAdmin utility, it is likely that a successful attack of this nature would permit an attacker to hijack an administrative account.

PSCS VPOP3 versions 2.0.0e and 2.0.0f have been reported to be prone to this vulnerability, however other versions may be affected as well.

Affected Products:

  • PSCS VPOP3 2.0.0e
  • PSCS VPOP3 2.0.0f
