A stored Cross-site Scripting (XSS) vulnerability exists in the MGate 5121/5122/5123 Series firmware version v1.0. This vulnerability is due to insufficient sanitization and encoding of user input in the "Login Message" functionality. An authenticated attacker with administrative access can exploit this vulnerability to inject malicious scripts that are continuously stored on the device. These scripts are executed when other users access the login page, potentially resulting in unauthorized actions or other impacts, depending on the user's privileges.
The severity level of this vulnerability is classified as medium, with a CVSS score of 5.2. It is crucial for organizations to understand the real-world implications of this vulnerability, as it may allow attackers to perform unauthorized actions, leading to potential data breaches or other significant impacts.
As of now, the exploitation status of this vulnerability is deferred, indicating that it has not been actively exploited in the wild. However, organizations should not dismiss its risk. Continuous monitoring for updates and vulnerabilities in their systems is essential.
Organizations should prioritize patching immediately. Early detection and remediation can significantly reduce the risk posed by such vulnerabilities.
Vulnerability Details
The official description outlines that a stored Cross-site Scripting (XSS) vulnerability exists in the MGate 5121/5122/5123 Series firmware version v1.0. The vulnerability arises from improper sanitization and encoding of user input in the "Login Message" feature. CVE-2025-0193 is classified under CWE-79, which pertains to improper neutralization of input during web page generation ('Cross-site Scripting').
The CVSS score of 5.2 indicates a medium severity, with the attack vector being network-based. Attack complexity is rated as high, requiring an attacker to have administrative privileges and a degree of user interaction, as they need to be authenticated before exploiting this vulnerability.
The vulnerability was published on January 15, 2025. Given the potential for significant impacts, organizations must ensure that they are aware of this vulnerability in their systems.
Technical Analysis
The root cause of this vulnerability lies in insufficient input validation and encoding practices. This flaw allows an attacker with administrative access to store scripts that are executed when other users visit the login page.
The attack vector is network-based, meaning that the attacker can exploit this vulnerability remotely. The complexity is considered high, as administrative access is required to inject the malicious scripts. User interaction is passive, as users will execute the malicious scripts without any additional actions.
The impacts of this vulnerability include high confidentiality, integrity, and availability impacts on the affected system. Organizations must be aware of the potential consequences of such vulnerabilities and take necessary precautions.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-0193 includes the potential for unauthorized access and actions performed by attackers. Given that administrative privileges are required for exploitation, organizations must ensure that proper access controls and monitoring mechanisms are in place to mitigate this risk.
This vulnerability could lead to a significant blast radius if exploited, as it affects multiple users accessing the login page. Organizations should prioritize this vulnerability in their risk assessment processes.
Based on its CVSS score, organizations should address this vulnerability in their priority patch cycle. Continuous monitoring for updates and potential exploits is critical for maintaining a robust security posture.

Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected product is MGate 5121/5122/5123 Series firmware version v1.0. As the version information is limited, organizations should consider all versions prior to vendor patch.
Mitigation & Remediation
Organizations should prioritize patching immediately. Ensure to upgrade to the latest firmware version provided by the vendor. If a patch is unavailable, consider implementing workarounds such as restricting administrative access and strengthening input validation measures in the application.
Network controls should be enforced to limit access to the management interface. Additionally, monitoring should be put in place to detect anomalous behavior that could indicate an exploitation attempt.
For further security enhancements, organizations may consider engaging in penetration testing to ensure overall system security.
Detection Guidance
Organizations should monitor logs for indicators of unauthorized access attempts or unusual script executions on the login page. Behavioral anomalies, such as unexpected changes in user roles or privileges, should also be flagged for further investigation.
Network signatures should be developed to identify any malicious requests targeting the login functionality. System changes that deviate from normal operations should be closely monitored.
AppSecure Threat Intelligence Insight
