    Active Exploitation

    TRC analysis shows Microsoft initially misclassified CVE-2024-38094 as a spoofing vulnerability (CVSS 6.5) when it actually enables authenticated remote code execution (CVSS 8.8). Attackers bypass SafeControls validation to deploy in-memory webshells in SharePoint environments. This misclassification may have led organizations to deprioritize critical patches. #CloudSecurity #Vulnerability 🔗 Full breakdown: https://aviatrix.ai/threat-research-center/sharepoint-cve-2026-65660-rce-vulnerability-microsoft-classification-error

    Post summary

    Microsoft misclassified CVE-2024-38094 as spoofing (CVSS 6.5) when it is actually authenticated RCE (CVSS 8.8); attackers are actively exploiting it via SafeControls bypass to deploy webshells in SharePoint, and organizations deprioritized patching due to the misclassification.

    TRC analysis shows attackers chaining CVE-2024-38094 and CVE-2024-38093 to bypass SharePoint JWT authentication and achieve remote code execution. Over 8,700 exposed instances face immediate risk as exploit chains enable lateral movement across SharePoint farms. Runtime segmentation helps limit blast radius in post-compromise scenarios. #CloudSecurity 🔗 Full TRC analysis: https://aviatrix.ai/threat-research-center/microsoft-sharepoint-rce-chain-cve-2026-55040-63520-exploit

    Post summary

    The analysis confirms that attackers are actively chaining CVE-2024-38094 and CVE-2024-38093 to bypass SharePoint authentication and achieve remote code execution across more than 8,700 exposed instances.
