#vulnerability

### Impact For users who deploy Hubble UI using either Cilium CLI or via the Cilium Helm chart, an insecure default `Access-Control-Allow-Origin` header value could lead to sensitive data exposure. A user with access to a Hubble UI instance affected by this issue could leak configuration details about the Kubernetes cluster which Hubble UI is monitoring, including node names, IP addresses, and other metadata about workloads and the cluster networking configuration. In order for this vulnerability to be exploited, a victim would have to first visit a malicious page. ### Patches This issue was patched in https://github.com/cilium/cilium/commit/a3489f190ba6e87b5336ee685fb6c80b1270d06d This issue affects: - Cilium between v1.14.0 and v1.14.18 inclusive - Cilium between v1.15.0 and v1.15.12 inclusive - Cilium between v1.16.0 and v1.16.5 inclusive This issue is patched in: - Cilium v1.14.19 - Cilium v1.15.13 - Cilium v1.16.6 ### Workarounds Users who deploy Hubble UI using the Ciliu...

### Impact In a Kubernetes cluster where Cilium is configured to proxy DNS traffic, an attacker can crash Cilium agents by sending a crafted DNS response to workloads from outside the cluster. For traffic that is allowed but without using DNS-based policy, the dataplane will continue to pass traffic as configured at the time of the DoS. For workloads that have DNS-based policy configured, existing connections may continue to operate, and new connections made without relying on DNS resolution may continue to be established, but new connections which rely on DNS resolution may be disrupted. Any configuration changes that affect the impacted agent may not be applied until the agent is able to restart. ### Patches This issue affects: - Cilium v1.14 between v1.14.0 and v1.14.17 inclusive - Cilium v1.15 between v1.15.0 and v1.15.11 inclusive - Cilium v1.16 between v1.16.0 and v1.16.4 inclusive This issue is fixed in: - Cilium v1.14.18 - Cilium v1.15.12 - Cilium v1.16.5 ### Workaroun...

A flaw was found in Keycloak. When an Active Directory user resets their password, the system updates it without performing an LDAP bind to validate the new credentials against AD. This vulnerability allows users whose AD accounts are expired or disabled to regain access in Keycloak, bypassing AD restrictions. The issue enables authentication bypass and could allow unauthorized access under certain conditions.

The flurry of non-human identity attacks at the end of 2024 demonstrates extremely strong momentum heading into the new year. That does not bode well.

Threat actors are exploiting an unspecified zero-day vulnerability in Cambium Networks cnPilot routers to deploy a variant of the AISURU botnet called AIRASHI to carry out distributed denial-of-service (DDoS) attacks. According to QiAnXin XLab, the attacks have leveraged the security flaw since June 2024. Additional details about the shortcomings have been withheld to prevent further abuse. Some

A vulnerability in 7-Zip that could allow attackers to bypass the MotW security feature in Windows has been patched.

As GenAI tools and SaaS platforms become a staple component in the employee toolkit, the risks associated with data exposure, identity vulnerabilities, and unmonitored browsing behavior have skyrocketed. Forward-thinking security teams are looking for security controls and strategies to address these risks, but they do not always know which risks to prioritize. In some cases, they might have

Oracle is urging customers to apply its January 2025 Critical Patch Update (CPU) to address 318 new security vulnerabilities spanning its products and services. The most severe of the flaws is a bug in the Oracle Agile Product Lifecycle Management (PLM) Framework (CVE-2025-21556, CVSS score: 9.9) that could allow an attacker to seize control of susceptible instances. "Easily exploitable

Despite lagging in technology adoption, African and Middle Eastern organizations are catching up, driven by smartphone acceptance and national identity systems.
