A critical Remote Code Execution (RCE) vulnerability in Microsoft SharePoint is currently being exploited to infiltrate corporate networks. Identified as CVE-2024-38094, this vulnerability allows attackers to run malicious code within SharePoint environments which seamlessly connect to Microsoft 365 apps. Through this exploit, attackers can gain unauthorized access to corporate data, manipulate files, and potentially gain control over network systems. This exploit is particularly concerning as it could be leveraged to escalate privileges, affecting broader systems within the network and compromising sensitive information. CISA added CVE-2024-38094 to the Known Exploitable Vulnerability (KEV) catalog indicating the vulnerability presents risk to Federal agencies and mandating its patching.
What You Can Do
IT administrators should urgently apply Microsoft's latest security patches for SharePoint to mitigate the risk of RCE attacks. Additionally, enabling multi-factor authentication (MFA), restricting administrative permissions, and conducting regular vulnerability assessments across all SharePoint instances can provide added layers of defense. Implementing strong network segmentation can also help limit exposure if a breach does occur, containing any potential damage to only the affected segment of the network.
