A security issue was discovered in Ingress-NGINX where the `mirror-target` and `mirror-host` Ingress annotations can be used to inject arbitrary configuration into NGINX. This vulnerability allows for arbitrary code execution in the context of the Ingress-NGINX controller, and disclosure of Secrets accessible to the controller. Organizations should prioritize patching immediately.
The CVSS score for this vulnerability is 8.8, indicating a high severity level. The potential risks include unauthorized access to sensitive data and the compromise of the application environment. It is crucial for organizations to address this vulnerability promptly to protect their systems.
Currently, exploitation status shows that there are known exploits available for this vulnerability. Organizations must remain vigilant and implement necessary mitigations to prevent potential breaches.
Given the high severity and exploitability of this vulnerability, organizations should take immediate action to patch affected systems and ensure that configurations are secure.
Vulnerability Details
The vulnerability, identified as CVE-2025-1098, relates to the Ingress-NGINX controller. The official description states that the `mirror-target` and `mirror-host` annotations are not properly sanitized, leading to potential configuration injection. This can result in arbitrary code execution and unintended access to Secrets.
The CVSS score of 8.8 reflects high severity, with confidentiality, integrity, and availability impacts rated as high. The attack vector is network-based, requiring low privileges and no user interaction.
The vulnerability was published on March 25, 2025, and is categorized under CWE-20.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user-supplied data within the Ingress annotations. Attackers may leverage this vulnerability by crafting malicious ingress configurations that inject arbitrary code into the NGINX runtime.
The attack vector is through the network, and the complexity is low since it requires only low privileges to execute. No user interaction is necessary, making it easier for attackers to exploit.
The potential impact on confidentiality, integrity, and availability is significant, as attackers can execute code and manipulate sensitive configurations.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to Secrets, potential data breaches, and disruption of services. The blast radius could extend to any service interacting with the Ingress-NGINX controller.
Given the active exploitation status and the high CVSS score, organizations should prioritize remediation efforts in their patch cycles. The urgency of addressing this vulnerability cannot be understated.
Organizations must ensure that their deployment of NGINX is secure and configured properly to prevent this vulnerability from being exploited.
