CVE-2024-6235 Scanner

NetScaler Console is a widely used solution for managing and monitoring network resources, employed in various sectors from corporate IT departments to service providers. It is developed by Citrix and is intended for optimizing, monitoring, and troubleshooting application performance in network environments. Its core functionality involves connecting and controlling applications and resources to secure and optimize network traffic. IT administrators utilize it to organize and secure application delivery, thus ensuring seamless access to critical applications. The software is pivotal in settings where high availability and real-time access to applications are essential. Its role expands across various networks to provide enhanced control over application delivery and security.

The vulnerability in question leads to sensitive information disclosure within the NetScaler Console environment. By exploiting this flaw, an attacker could potentially access confidential information without proper authorization. It arises when certain configurations or default settings allow access to sensitive data endpoints. Such vulnerabilities are often serious as they can expose critical data like authentication credentials or configuration secrets. Unauthorized information access can lead to broader security breaches due to the sensitive nature of exposed data. Mitigating this vulnerability is crucial to maintaining the integrity and confidentiality of network operations managed by the NetScaler Console.

The technical details reveal that the vulnerability exploits a specific endpoint within the NetScaler Console's configuration management system. The vulnerable endpoint can be accessed using a specially crafted HTTP GET request, targeting secret configuration data. Additionally, specific HTTP headers are used, including 'AD_SESSIONID' and 'mps_secret', indicating an unauthorized yet possible information extraction from affected systems. The matcher conditions such as checking status 200 and specific JSON elements reflect how an attack could be confirmed. The exposure depends on inadequate security measures or default configurations not being altered by the administrator.

When exploited by malicious actors, this vulnerability could lead to severe consequences such as unauthorized access to sensitive administrative functions and leakage of confidential information. Attackers might use the disclosed information to further compromise the network, potentially leading to larger security breaches. The trustworthiness of the application delivery mechanism could be undermined, potentially leading to denial of service situations or degraded performance due to tampered configurations. Additionally, the organization might face operational, reputational, and financial damages as a result of such exposure.
