Overview

A serious vulnerability has been discovered in the WordPress core that allows unauthenticated attackers to execute code on affected sites. This flaw impacts any WordPress installation running versions 6.9 and 7.0, even those without any plugins installed. The issue was identified by Adam Kues from Assetnote, and WordPress has since addressed it with updates 6.9.5 and 7.0.2, which were released on Friday. These updates include a feature called forced updates to help secure sites against this vulnerability. It's crucial for WordPress users to ensure they are running the latest version to protect their sites from potential exploitation.

Key Takeaways

  • Active Exploitation: This vulnerability is being actively exploited by attackers. Immediate action is recommended.
  • Affected Systems: WordPress versions 6.9 and 7.0
  • Action Required: Update to WordPress version 6.
  • Timeline: Disclosed on [date of report]

Original Article Summary

An anonymous HTTP request can run code on a WordPress site. The bug is in core, so a bare install with zero plugins is exploitable. Every 6.9 and 7.0 site was in range until Friday, when WordPress shipped 6.9.5 and 7.0.2 and enabled what it calls forced updates through its auto-update system. Adam Kues at Assetnote, Searchlight Cyber's attack surface management arm, found the flaw and reported

New Russian-speaking threat actor UAT-11795 targets US and Europe with novel malware

SCM feed for Latest

A new Russian-speaking hacking group known as UAT-11795 is targeting organizations in the United States and Europe. This group is using innovative malware tools, specifically the Starland Remote Access Trojan (RAT) built with Python and the PowerShell-based WLDR agent, which operates solely in memory. These tools are designed to evade detection through encrypted communications and a unique execution environment. The emergence of UAT-11795 raises concerns for businesses and government entities, as their tactics could lead to significant data breaches or system compromises. As cyber threats continue to evolve, organizations need to be vigilant and enhance their security measures to defend against such sophisticated attacks.

Filtering Known-Bad Messages Does Not Prove Detection Readiness

SCM feed for Latest

The article discusses the inadequacy of measuring cybersecurity effectiveness solely by block rates of known-bad messages. It argues that just because a system can block certain threats does not mean it is fully prepared to detect and respond to all potential attacks. This is a significant point for organizations relying on these metrics, as it may give a false sense of security. The piece emphasizes the need for a deeper understanding of detection capabilities rather than just focusing on how many threats are blocked. By doing so, organizations can better assess their true security posture and improve their defenses against evolving threats.

OpenSSL HollowByte Flaw Could Freeze Server Memory with 11-Byte TLS Requests

The Hacker News

A recently discovered vulnerability in OpenSSL, dubbed the HollowByte flaw, can cause unpatched servers to reserve up to 131 KB of memory for a tiny 11-byte TLS request that never arrives. This issue can lead to a denial-of-service condition, where the server's memory is tied up until the process is restarted. The problem was identified by Okta's Red Team, which reported it without a CVE or formal advisory. OpenSSL issued a fix for this vulnerability in June, but the lack of documentation means many users may remain unaware of the risk. As a result, organizations running affected OpenSSL versions should ensure they apply the update to avoid potential service disruptions.
