CVE-2019-25426 is a reflected cross-site scripting (XSS) vulnerability in Comodo Dome Firewall version 2.7.0. It allows attackers to inject malicious scripts by sending specially crafted input to the dnsmasq endpoint. Specifically, attackers can send POST requests containing script payloads in the TRANSPARENT_SOURCE_BYPASS or TRANSPARENT_DESTINATION_BYPASS parameters, which results in the execution of arbitrary JavaScript code in the browsers of users who access the vulnerable endpoint.
How can this vulnerability impact me? :
This vulnerability can impact you by allowing attackers to execute arbitrary JavaScript in your users' browsers. This can lead to a variety of malicious outcomes such as stealing session cookies, redirecting users to malicious websites, performing actions on behalf of the user without their consent, or delivering malware. Since the attack requires user interaction (UI:R), it may be triggered when a user visits a crafted page or interacts with the vulnerable service.
