Official Description

Login.aspx in the SmarterTools SmarterStats 6.0 web server supports URLs containing txtUser and txtPass parameters in the query string, which makes it easier for context-dependent attackers to discover credentials by reading (1) web-server access logs, (2) web-server Referer logs, or (3) the browser history, related to a "cross-domain Referer leakage" issue.

Technical Analysis

CVE-2011-2153 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
