Azure Kubernetes Service
Monthly
Privilege elevation in Microsoft Azure Kubernetes Service (AKS) lets a network-based, unauthenticated attacker gain elevated privileges by reaching a critical function that lacks an authentication check (CWE-306). Microsoft rates it 9.4 (Critical) with an AV:N/AC:L/PR:N/UI:N vector, indicating trivial remote reachability and no user interaction, though scope is unchanged. There is no public exploit identified at time of analysis and it is not on CISA KEV, but the missing-auth root cause and high confidentiality/integrity impact make it a high-priority cloud-platform issue.
Complete cluster compromise via missing authentication in Microsoft Azure Kubernetes Service allows any unauthenticated remote attacker to gain administrative privileges over the network. No user interaction is required, and the vulnerability is automatable, enabling full cluster takeover with potential cross-tenant impact. No public exploit code or active exploitation has been reported, and a vendor patch is available.
Local privilege escalation and code execution in Microsoft Azure Kubernetes Service (AKS) is possible via a path traversal flaw (CWE-22) that allows an authorized attacker on the local system to break out of restricted directory boundaries and execute code with elevated privileges. The CVSS 3.1 score of 8.8 reflects the scope change (S:C) where exploitation impacts resources beyond the vulnerable component, enabling full confidentiality, integrity, and availability compromise. No public exploit identified at time of analysis.
Microsoft Azure Kubernetes Service (AKS) contains an improper authorization vulnerability enabling unauthenticated remote attackers to elevate privileges over a network with critical impact across confidentiality, integrity, and availability. The CVSS 10.0 critical rating reflects network-accessible exploitation requiring no authentication, low complexity, and scope change allowing compromise beyond the vulnerable component. No public exploit identified at time of analysis, though the authentication bypass nature and maximum severity warrant immediate priority.
Denial of service against HTTP/2 server implementations allows remote unauthenticated attackers to exhaust server resources by rapidly opening and immediately canceling (RST_STREAM) large numbers of streams over a single connection, a technique dubbed the 'Rapid Reset' attack. The flaw is confirmed actively exploited (CISA KEV) following large-scale weaponization observed August through October 2023, with publicly available exploit code and an EPSS score of 94.45% placing it in the 100th percentile for likelihood of exploitation. Virtually every major HTTP/2 stack - including nghttp2, Netty, Envoy, and Eclipse Jetty - is affected.
