Executive Summary

CVE-2019-25424 is a reflected cross-site scripting (XSS) vulnerability in Comodo Dome Firewall version 2.7.0. It occurs because the firewall does not properly sanitize input submitted to the EXCEPTIONSITELIST parameter. Attackers can send specially crafted POST requests to the https_exceptions endpoint containing malicious script payloads. When these scripts are executed in the browsers of users who interact with the vulnerable endpoint, attackers can run arbitrary JavaScript code.

Impact Analysis

This vulnerability can allow attackers to execute arbitrary JavaScript in the context of a user's browser session. This can lead to theft of session data, which may include authentication tokens or other sensitive information. As a result, attackers could impersonate users, gain unauthorized access, or perform actions on behalf of the user without their consent.
