CVE-2022-31137 Scanner

The Roxy-WI software is a popular web-based interface used by system administrators and IT professionals for managing and configuring HAProxy, Nginx, and Keepalived servers. This tool is widely deployed in data centers and critical infrastructure environments to facilitate the management of server load balancing and high availability configurations. Organizations rely on Roxy-WI's comprehensive features to streamline server management tasks and improve operational efficiency. Due to its extensive features, Roxy-WI is used in various industries, including telecommunications, finance, and healthcare. Being an open-source solution, it allows for cost-effective server management without the need for expensive proprietary software solutions. Regular updates and community contributions help maintain its relevance and security through active development.

Remote Code Execution (RCE) refers to a vulnerability that allows an attacker to execute arbitrary or malicious code on a target system remotely. This particular vulnerability in Roxy-WI arises from insufficient input validation in the subprocess_execute function within the application's backend code. RCE vulnerabilities can lead to unauthorized access, data breaches, and full system compromise if not addressed promptly. Such vulnerabilities pose significant security risks, particularly in environments like Roxy-WI, which are responsible for maintaining the availability and performance of multiple critical server applications. Attackers exploiting RCE vulnerabilities can bypass security measures, escalate privileges, and potentially take control of affected systems. Proper mitigation strategies, such as regular updates and input validation improvements, are essential to prevent exploitation.

The Roxy-WI vulnerability involves the subprocess_execute function, which fails to properly sanitize user inputs in the /app/options.py file. The vulnerable endpoint allows attackers to inject and execute arbitrary system commands by manipulating the input data sent to the server. This flaw is critical as it enables attackers to access sensitive files, modify system settings, or introduce malicious software without authentication. The specific HTTP request utilized in exploiting this vulnerability includes payloads that target the command injection flaw to execute commands like 'cat /etc/passwd,' providing unauthorized access to sensitive information. The combination of technical oversight and the critical nature of the Roxy-WI deployment environment underscores the urgency of addressing this vulnerability.

Exploitation of this vulnerability can have severe repercussions, including unauthorized access to sensitive data, disruption of server operations, and potential footholds for further attacks on the internal network. Successfully executed attacks can result in severe financial and reputational damage for the affected organizations. Moreover, since Roxy-WI configurations often interact with multiple critical server systems, the threat vector of a compromised environment could extend beyond the initial target. In the worst-case scenario, attackers can use compromised servers as launchpads for more extensive, network-wide cyberattacks, including data exfiltration or ransomware deployments.
