CVE-2019-25412 in Comodo Dome Firewall
Summary
by MITRE • 02/19/2026
Comodo Dome Firewall 2.7.0 contains a reflected cross-site scripting vulnerability that allows attackers to inject malicious scripts by submitting unsanitized input through the NTP_SERVER_LIST parameter. Attackers can send POST requests to the /korugan/time endpoint with script payloads in the NTP_SERVER_LIST parameter to execute arbitrary JavaScript in users' browsers.

The vulnerability identified as CVE-2019-25412 resides within Comodo Dome Firewall version 2.7.0, a network security solution designed to protect enterprise environments from various cyber threats. This particular flaw represents a critical security weakness that undermines the integrity of the application's input validation mechanisms, creating an avenue for malicious actors to compromise user sessions and execute unauthorized code within the context of affected browsers. The vulnerability specifically targets the application's handling of user-supplied data through the NTP_SERVER_LIST parameter, which is processed by the /korugan/time endpoint. This endpoint serves as a communication channel for time synchronization configuration within the firewall management interface, making it a legitimate and frequently accessed component of the system's operational functionality.
The technical implementation of this reflected cross-site scripting vulnerability stems from insufficient input sanitization and output encoding within the web application's backend processing logic. When the application receives a POST request containing the NTP_SERVER_LIST parameter, it fails to properly validate or sanitize the input data before incorporating it into the HTTP response sent back to the user's browser. This omission creates a scenario where malicious payloads can be injected directly into the web page's HTML output, resulting in the execution of arbitrary JavaScript code within the victim's browser context. The reflected nature of this vulnerability means that the malicious script is not stored on the server but rather injected through a crafted request that is immediately reflected back to the user, making it particularly dangerous as it can be delivered through various attack vectors including phishing emails, malicious links, or compromised websites that redirect users to the vulnerable endpoint.
The operational impact of this vulnerability extends beyond simple script execution, potentially enabling attackers to perform a wide range of malicious activities within the compromised browser sessions. Security researchers have classified this vulnerability under CWE-79, which specifically addresses Cross-site Scripting flaws in web applications, and it aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments or links. Attackers can leverage this vulnerability to steal session cookies, perform unauthorized administrative actions, redirect users to malicious websites, or even establish persistent backdoors within the browser environment. The implications are particularly severe given that Comodo Dome Firewall is typically deployed in enterprise environments where users may have elevated privileges or access to sensitive network resources, potentially allowing attackers to escalate their privileges and gain unauthorized access to critical infrastructure components.
Mitigation strategies for this vulnerability require immediate attention from system administrators and security teams responsible for maintaining the Comodo Dome Firewall environment. The primary remediation approach involves implementing proper input validation and output encoding mechanisms throughout the application's codebase, specifically targeting the NTP_SERVER_LIST parameter handling within the /korugan/time endpoint. Organizations should prioritize updating to the latest available version of Comodo Dome Firewall that contains the patched implementation, as the vendor has likely released a security update addressing this specific flaw. Additionally, network administrators should implement web application firewalls or security controls that can detect and block malicious payloads attempting to exploit this vulnerability, while also conducting thorough penetration testing and vulnerability assessments to identify any similar weaknesses in the broader network infrastructure. Security monitoring should be enhanced to detect anomalous traffic patterns associated with exploitation attempts, and user education programs should be implemented to raise awareness about the risks of clicking suspicious links or downloading untrusted content that could potentially trigger this vulnerability.
