The NGINX Ingress Controller is vulnerable due to an injection flaw in its configuration generator, allowing authenticated attackers with write access to Ingress annotations to inject arbitrary NGINX configuration directives. This could lead to unauthorized file manipulation, service disruption, or other control plane compromises. Organizations using NGINX Ingress Controller within Kubernetes environments should prioritize patching this vulnerability to mitigate potential risks.

Original NVD Description

When NGINX Ingress Controller is configured with Ingress annotations, an injection vulnerability exists in the configuration generator of NGINX Ingress Controller. Multiple user-controllable fields are written into the generated NGINX configuration without sanitization. An authenticated attacker with permission to create or modify these annotations may craft values that inject arbitrary NGINX configuration directives. Impact: An authenticated attacker granted write access to NGINX Ingress Controller Ingress annotations through the Kubernetes API may be able to inject arbitrary NGINX configuration directives, create or delete files, or disable services. There is no data plane exposure; this is a control plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
