Description:

The multicluster engine for Kubernetes operator 2.1.9 images

The multicluster engine for Kubernetes operator provides the foundational components that are necessary for the centralized management of multiple  
Kubernetes-based clusters across data centers, public clouds, and private  
clouds.

You can use the engine to create new Red Hat OpenShift Container Platform  
clusters or to bring existing Kubernetes-based clusters under management by  
importing them. After the clusters are managed, you can use the APIs that  
are provided by the engine to distribute configuration based on placement  
policy.

Red Hat Security Advisory 2023-6200-01

F5 has warned customers about a critical vulnerability impacting BIG-IP that could result in unauthenticated remote code execution.

Tech company F5 has warned customers about a critical authentication bypass vulnerability impacting its BIG-IP product line that could result in unauthenticated remote code execution.

F5 provides services focused on security, reliability, and performance. BIG-IP is a collection of hardware platforms and software solutions that provides a wide range of services, including load balancing, web application firewall, access control, and DDoS protection.

Two security researchers found a critical vulnerability in the configuration utility of several versions of BIG-IP:

*   17.1.0 (Fixed in 17.1.0.3 + Hotfix-BIGIP-17.1.0.3.0.75.4-ENG)
*   16.1.0 – 16.1.4 (Fixed in 16.1.4.1 + Hotfix-BIGIP-16.1.4.1.0.50.5-ENG)
*   15.1.0 – 15.1.10 (Fixed in 15.1.10.2 + Hotfix-BIGIP-15.1.10.2.0.44.2-ENG)
*   14.1.0 – 14.1.5 (Fixed in 14.1.5.6 + Hotfix-BIGIP-14.1.5.6.0.10.6-ENG)
*   13.1.0 – 13.1.5 (Fixed in 13.1.5.1 + Hotfix-BIGIP-13.1.5.1.0.20.2-ENG)

In a post, F5 said:

> “This vulnerability may allow an unauthenticated attacker with network access to the BIG-IP system through the management port and/or self IP addresses to execute arbitrary system commands.”

F5 also said customers can also use iHealth to check if they are vulnerable.

The Common Vulnerabilities and Exposures (CVE) database lists publicly disclosed computer security flaws. This CVEs is listed as:

CVE-2023-46747 (CVSS score 9.8 out of 10): Undisclosed requests may bypass configuration utility authentication, allowing an attacker with network access to the BIG-IP system through the management port and/or self IP addresses to execute arbitrary system commands.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

BIG-IP defines a self IP address as an IP address on the BIG-IP system that you associate with a virtual local area network (VLAN), to access hosts in that VLAN. A  customer normally assigns self IP addresses to a VLAN when they initially run the Setup utility on a BIG-IP system.

An authentication bypass happens when someone claims to have a given identity, but the software does not prove or insufficiently proves that the claim is correct.

Remote code execution (RCE) is when an attacker accesses a target computing device and makes changes remotely, no matter where the device is located.

In general you can say that if the BIG-IP Traffic Management User Interface is exposed to the internet, then the system in question is impacted. It’s estimated that there are over 6,000 external-facing instances of the application.

The researchers say exploitation of the vulnerability could lead to a total compromise of the F5 system by executing arbitrary commands as root on the target system.

> “A seemingly low impact request smuggling bug can become a serious issue when two different services offload authentication responsibilities onto each other.”

**Actions**

If you are running a vulnerable version, F5 has a list of updates here.

If you can’t install a fixed version for any reason, then F5 advises you can block Configuration utility access through self IP addresses or block Configuration utility access through the management interface.

**We don’t just report on vulnerabilities—we identify them, and prioritize action.**

Cybersecurity risks should never spread beyond a headline. Keep vulnerabilities in tow by using Malwarebytes Vulnerability and Patch Management.

 Patch now! BIG-IP Configuration utility is vulnerable for an authentication bypass

Red Hat Security Advisory 2023-6021-01

Groups have fallen silent after bold claims of action at the start of the conflict.

Hacktivist cyber activities around the Israel-Hamas conflict have significantly slowed, with some groups no longer plotting such attacks and others focusing on targets outside Israel.

Research of Dark Web discussions released this month by Security Scorecard found several hacktivist groups had made plans to conduct attacks or identified targets to be attacked, but many groups have since fallen silent or resorted to selling attack services.

A pro-Palestinian group, Dark Storm Team, posted claims in August 2023 on Dark Web forums that it would "attack Israel infrastructure," and in early October, claimed to be preparing attacks against Israel's European allies. However, as of Oct. 20, it had reverted to promoting its DDoS-as-a-service options.

Many hacktivist groups threatened to launch disruptive attacks against Israel and Palestine, while the hacktivist group SiegedSec claimed responsibility for a series of attacks against Israeli infrastructure and industrial control systems.

In addition, the Persian language-speaking, pro-Palestinian hacktivist channel Solomon's Ring has not claimed an attack since Oct. 8. Despite being active since October 2022 and its claims of hacking and stealing data from an Israeli data center, there is no evidence of this nor of any leaks of that data.

KillNet Palestine (potentially a division of the Russian hacktivist group KillNet), meanwhile, has not posted any new content since a message announcing its formation on Oct 13.

Description:

Multicluster Engine for Kubernetes 2.2.9 images

Multicluster engine for Kubernetes provides the foundational components  
that are necessary for the centralized management of multiple  
Kubernetes-based clusters across data centers, public clouds, and private  
clouds.

You can use the engine to create new Red Hat OpenShift Container Platform  
clusters or to bring existing Kubernetes-based clusters under management by  
importing them. After the clusters are managed, you can use the APIs that  
are provided by the engine to distribute configuration based on placement  
policy.
