Analysis Summary

Ivanti has disclosed that active exploitation of a recently patched security vulnerability in their Cloud Service Appliance (CSA) has occurred in the wild. CVE-2024-8190 (CVSS score: 7.2) is the high-severity vulnerability in question that, in certain situations, permits remote code execution.

Ivanti Cloud Services Appliance versions 4.6 Patch 518 and earlier have an OS command injection vulnerability that makes it possible for a remote, authorized attacker to execute code remotely. To take advantage of this vulnerability, the attacker has to have administrator-level access. Ivanti CSA 4.6, which is currently end-of-life due to a fault, means that clients will need to switch to a supported version going forward. Having stated that, CSA 4.6 Patch 519 addresses it.

This is the final patch that Ivanti will backport for this version due to its end-of-life status. For ongoing support, users must upgrade to Ivanti CSA 5.0. The only version that is supported and does not have this vulnerability is CSA 5.0. Clients who are currently using Ivanti CSA 5.0 don't need to do anything further. Ivanti modified its advisory on Friday, stating that it had seen verified exploits of the vulnerability in the wild, which were directed at a restricted group of clients.

It did not disclose any more information about the attacks or the identity of the threat actors using it as a weapon; yet, China-affiliated cyber espionage groups have leveraged several other vulnerabilities in Ivanti products as zero-day exploits. The development has compelled federal entities to implement the remedies by October 4, 2024, as per the U.S. Cybersecurity and Infrastructure Security Agency's (CISA) addition of the vulnerability to its Known Exploited Vulnerabilities (KEV) database.
