GoCD has released a security update to address a critical authentication vulnerability in GoCD versions 20.6.0 through 21.2.0. GoCD is an open-source Continuous Integration and Continuous Delivery system. A remote attacker could exploit this vulnerability to obtain sensitive information.

CISA encourages users and administrators to update to GoCD 21.3.0 or apply the necessary workarounds.

For more information, see Agent 007: Pre-Auth Takeover of Build Pipelines in GoCD.

The National Security Agency (NSA) and CISA have published the first of a four-part series, Security Guidance for 5G Cloud Infrastructures. Security Guidance for 5G Cloud Infrastructures – Part I: Prevent and Detect Lateral Movement provides recommendations for mitigating lateral movement attempts by threat actors who have gained initial access to cloud infrastructures. 

This guidance has been created by the Critical Infrastructure Partnership Advisory Council (CIPAC) Cross Sector Enduring Security Framework Working Group—a public-private working group that provides cybersecurity guidance addressing high-priority cyber threats to the nation’s critical infrastructure. 

CISA encourages 5G providers, integrators, and network operators to review the guidance and consider the recommendations.

The Homeland Security Systems Engineering and Development Institute, sponsored by the Department of Homeland Security and operated by MITRE, has released the 2021 Common Weakness Enumeration (CWE) Most Important Hardware Weaknesses List. The 2021 Hardware List is a compilation of the most frequent and critical errors that can lead to serious vulnerabilities in hardware. An attacker can often exploit these vulnerabilities to take control of an affected system, obtain sensitive information, or cause a denial-of-service condition.
 
CISA encourages users and administrators to review the Hardware Weaknesses List and evaluate recommended mitigations to determine those most suitable to adopt.

Defending against ransomware will take a move to zero-trust, argues Daniel Spicer, CSO, Ivanti.

The flaw, found in the Hashthemes Demo Importer plugin, allows any authenticated user to exsanguinate a vulnerable site, deleting nearly all database content and uploaded media.

Out of 92 security vulnerabilities, 66 are rated critical in severity, mostly allowing code execution. The most severe can lead to information disclosure.

A researcher was able to crack 70 percent of the gathered hashes in an experiment in a residential neighborhood.

The Federal Bureau of Investigation (FBI) has released a Flash report detailing indicators of compromise (IOCs) associated with attacks using Ranzy Locker, a ransomware variant first identified targeting victims in the United States in late 2020.

CISA encourages users and administrators to review the IOCs and technical details in FBI Flash CU-000153-MW and apply the recommend mitigations.

Researchers found that one critical flaw in question is exploitable from the browser, allowing watering-hole attacks.

Much is made of shared responsibility for cloud security. But Oliver Tavakoli, CTO at Vectra AI, notes there’s no guarantee that Azure or AWS are delivering services in a hardened and secure manner.
