Summary

A command injection vulnerability has been discovered in the web components of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure (9.x, 22.x) that allows an authenticated administrator to send specially crafted requests and execute arbitrary commands on the appliance. Mandiant has identified zero-day exploitation of these vulnerabilities in the wild by a suspected espionage threat actor. Several custom malware families, including web shells and a credential harvester, have been associated with the exploitation, indicating the threat actor's intent to maintain a presence on compromised targets. Ivanti has issued mitigations and is developing patches, with a significant increase in threat actor activity targeting the vulnerabilities since they were disclosed. More than 1,700 devices have been exploited worldwide, with global government and military departments, national telecommunications companies, and defense contractors among the victims. It is suspected that additional threat actors beyond the initial exploitation group may also have access to the exploit. Organizations are urged to implement mitigations immediately and apply patches as they are released to avoid potential exploitation.
