West Houston, TX – In light of Microsoft’s latest Patch Tuesday rollout, Impress IT Solutions is advising businesses across West Houston to act quickly and update their systems. The tech giant has released fixes for 125 security vulnerabilities, including a critical Windows zero-day flaw that is actively being exploited by ransomware groups.
“This kind of vulnerability is exactly what ransomware operators wait for,” said the cybersecurity team at Impress IT Solutions. “When Microsoft confirms real-world attacks are already underway, it’s a sign for every business to patch fast.”
The Most Concerning Threat: CLFS Elevation of Privilege Bug (CVE-2025-29824)
At the center of the warning is CVE-2025-29824, a flaw in the Windows Common Log File System (CLFS). This vulnerability allows attackers with local access to gain SYSTEM-level privileges—effectively full control of the system—without requiring admin credentials.
Microsoft confirmed that this flaw has already been used in ransomware attacks and has added it to its Known Exploited Vulnerabilities (KEV) list.
“Attackers are using this to escalate access and deploy ransomware after the initial compromise,” said Impress IT. “Businesses that don’t patch quickly are playing with fire.”
