Intelligence Summary
CISA says ransomware groups are actively exploiting a high-severity Microsoft SharePoint remote code execution flaw. The vulnerability has been under active exploitation since early July, according to the agency. Successful exploitation can allow attackers to run code on affected SharePoint deployments. This increases the likelihood of follow-on ransomware deployment and wider compromise. Organizations using SharePoint should review CISA guidance, ensure patches are applied, and check for signs of exploitation.
Recommended Action
Prioritize immediate review, validate exposure, and patch or mitigate affected systems.
