Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2021-25743)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-2431)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists in Kubelet that allows pods to bypass the seccomp profile enforcement. Pods that use localhost type for seccomp profile but specify an empty profile field, are affected by this issue. In this scenario, this vulnerability allows the pod to run in unconfined (seccomp disabled) mode


3) Improper locking (CVE-ID: CVE-2024-0793)

The vulnerability allows a local user to perform a denial of service attack (DoS).

The vulnerability exists due to improper locking when handling a malformed HPA v1 manifest in kube-controller-manager. A local user can perform a denial of service (DoS) attack.


4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-3177)

The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due to improper access restrictions. A remote user can launch containers that bypass the mountable secrets policy enforced by the ServiceAccount admission plugin when using containers, init containers, and ephemeral containers with the envFrom field populated.

Kubernetes clusters are only affected if the ServiceAccount admission plugin and the kubernetes.io/enforce-mountable-secrets annotation are used together with containers, init containers, and ephemeral containers with the envFrom field populated.


5) Input validation error (CVE-ID: CVE-2025-22872)

The vulnerability allows a remote attacker to perform code injection attacks.

The vulnerability exists due to insufficient validation of tags with unquoted attribute values that end with a solidus character (/). The tokenizer can interpret such tags as self-closing, leading to content following such tags as being placed in the wrong scope during DOM construction.
