Cisco has released software updates to address a critical security flaw impacting Meeting Management that could permit a remote, authenticated attacker to gain administrator privileges on susceptible instances. The vulnerability, tracked as CVE-2025-20156, carries a CVSS score of 9.9 out 10.0. It has been described as a privilege escalation flaw in the REST API of Cisco Meeting Management. "This vulnerability exists because proper authorization is not enforced upon REST API users," the company said in a Wednesday advisory. "An attacker could exploit this vulnerability by sending API requests to a specific endpoint." "A successful exploit could allow the attacker to gain administrator-level control over edge nodes that are managed by Cisco Meeting Management." The networking equipment major credited Ben Leonard-Lagarde of Modux for reporting the security shortcoming. It affects the following versions of the product irrespective of device configuratio...

If you use Linux on your company's desktop or server computers, you're likely familiar with the security advantages the open-source operating system offers over Windows and Mac. What many people don't realize, however, is that Linux can also rescue a computer crippled by malware. Malware is a frequent issue in the Windows world, and it can be devastating. When a Windows virus strikes, it can become difficult or even impossible to continue using the affected machine. Moreover, prolonged use can further the infection. Here's how Linux can help you recover from such a situation without ever installing it permanently on your PC. Step 1: Get a LiveCD or Live USB LiveCDs and USBs are great because they let you boot a machine directly from the CD or USB stick without accessing the computer's boot records. They allow you to test Linux and can be used when Windows fails. The fastest way to get a LiveCD or USB is to download the .iso file of the Linux distribution you wan...

In cybersecurity, confidence is a double-edged sword. Organizations often operate under a false sense of security , believing that patched vulnerabilities, up-to-date tools, polished dashboards, and glowing risk scores guarantee safety. The reality is a bit of a different story. In the real world, checking the right boxes doesn't equal being secure. As Sun Tzu warned, "Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat." Two and a half millennia later, the concept still holds: your organization's cybersecurity defenses must be strategically validated under real-world conditions to ensure your business's very survival. Today, more than ever, you need Adversarial Exposure Validation (AEV) , the essential strategy that's still missing from most security frameworks. The Danger of False Confidence Conventional wisdom suggests that if you've patched known bugs, deployed a stack of well-regarded security tools, and passed the nec...
