VMware Operations Manager Remote Code Execution Scanner

vRealize Operations Manager is a management software used by IT administrators and professionals aimed at optimizing, managing, and monitoring the data center and cloud infrastructure. It provides functionalities such as performance monitoring, capacity management, and troubleshooting capabilities. Organizations rely on it to increase effectiveness and deliver operational insights across multiple platforms. The software is integrated into VMware environments, allowing for comprehensive oversight and improved operational efficiencies. It is utilized across industries to support virtual environments, reducing downtime and improving performance metrics. vRealize Operations Manager supports the optimization of resources and simplifies management efforts in complex IT infrastructures.

The Remote Code Execution (RCE) vulnerability allows an attacker to execute arbitrary code on a vulnerable system. This issue arises from weaknesses in the Apache Log4j framework used by VMware Operations Manager. Exploiting this vulnerability does not require valid user credentials, making it particularly dangerous. An attacker can leverage the vulnerability to inject and run malicious scripts remotely. The exploitation might lead to unauthorized access, data compromise, and an overall system breach. The Apache Log4j issue (CVE-2021-44228) is a critical threat affecting millions globally, spurring widespread alerts and patches since discovery.

The vulnerability is rooted in the way vRealize Operations Manager processes specific log requests via Apache Log4j. Attackers can exploit this by submitting crafted input that triggers code execution through JNDI (Java Naming and Directory Interface). The vulnerability is particularly prominent in the login action, where a malicious payload can be inserted. This crafted payload may reach the vulnerable code path, executing code without authorization or user interaction. The flaw demonstrates a significant security gap due to insufficient input validation. Systems susceptible to this flaw must treat Log4j log messages with caution to prevent exploitation.

Exploitation of this vulnerability can have severe consequences, leading to unauthorized access and complete control over the affected system. Systems compromised through RCE may become conduits for further intrusion and pivot attacks. Attackers could install backdoors, exfiltrate sensitive data, disrupt services, and cause operational downtime. The breach poses a major risk to business continuity and data integrity. Additionally, the compromise can also impact regulatory compliance, as sensitive data may be exposed or altered.
