VMware vRealize Log RCE Exploit Release: Horizon3s Attack Team PoC Exploit Code

Researchers from the Horizon3s Attack Team have released PoC exploit code for remote code execution in VMware vRealize Log. This code triggers a series of flaws in the product to achieve remote code execution on vulnerable installs. VMware Aria Operations for Logs is a log collection and analytics virtual appliance that enables administrators to collect, view, manage and analyze syslog data. Log Insight provides real-time monitoring of application logs, network traces, configuration files, messages and performance data. The availability of an exploit like the one announced by the Horizon3s Attack Team is a bad news for organizations, as a threat actor can develop its own version to gain initial access to targets networks and perform a broad range of malicious activities. This vulnerability is easy to exploit however, it requires the attacker to have some infrastructure setup to serve malicious payloads. Additionally, since this product is unlikely to be exposed to the internet, the attacker likely has already established a foothold somewhere else on the network. This vulnerability allows for remote code execution as root, essentially giving an attacker complete control over the system. This week VMware addressed multiple vulnerabilities, tracked as CVE-2022-31706, CVE-2022-31704, CVE-2022-31710, and CVE-2022-31711, in its vRealize Log Insight appliance. The most severe flaws impacting the product are a Directory Traversal Vulnerability tracked as CVE-2022-31706, and a broken access control vulnerability tracked as CVE-2022-31704. An unauthenticated, attacker can exploit one of the two flaws to inject files into the operating system of an impacted appliance which can result in remote code execution. The post published by the Horizon3s Attack Team researchers also includes a list of indicators of compromise that can be used to detect exploitation attempts for the above issues. Gaining access to the Log Insight host provides some interesting possibilities to an attacker depending on the type of applications that are integrated with it. Often logs ingested may contain sensitive data from other services and may allow an attack to gather session tokens, API keys, and PII. Those keys and sessions may allow the attacker to pivot to other systems and further compromise the environment. The experts used the Shodan search engine and discovered only 45 VMware vRealize Log Insight appliances that are exposed online.
