CVE-2022-31161 Scanner

Roxy-WI is an interface for managing the HAProxy, Nginx, and Keepalived services. Used by network administrators and DevOps engineers, it allows for efficient and reliable deployment and management of network services. The system supports scalability and automation, serving enterprises that require robust network management solutions. Roxy-WI is valued for its intuitive UI, enhanced monitoring capabilities, and accessibility over web browsers. It enables teams to configure, monitor, and manage network infrastructure remotely and efficiently. As a widely used tool, maintaining its security becomes paramount to prevent unauthorized access and exploitation.

The Remote Code Execution (RCE) vulnerability in Roxy-WI allows attackers to execute arbitrary code on the affected system. It arises due to insufficient input validation in the application's codebase. Attackers can inject arbitrary OS commands through the delcert parameter without proper input checks. This form of exploitation represents a severe threat as it potentially compromises system integrity. If successfully exploited, attackers can gain remote control over the server, leading to unauthorized data access or disruptions in service. Given its critical nature, immediate remediation is essential to safeguard affected systems.

This vulnerability is located in the /app/options.py file and involves the delcert parameter. Attackers can exploit this endpoint using specially crafted requests to inject arbitrary commands. Without proper validation and sanitation of input parameters, this becomes a gateway for executing harmful commands on the system. The attack payload typically involves modifying HTTP requests to include the injected code within legal parameters. Detection requires scrutinizing HTTP interactions and analyzing anomalous requests containing suspicious command patterns. The risk is exacerbated in environments where Roxy-WI spans multiple critical network services.

The potential effects of exploiting this RCE vulnerability are profound and damaging. An attacker who successfully exploits the vulnerability could execute any command on the server, leading to unauthorized data breaches. Furthermore, it offers the ability to install malware, modify or delete data, and possibly escalate privileges for further exploitation. The breach of Roxy-WI can result in service downtime and consequential financial and reputational damage. It poses a threat to the confidentiality, integrity, and availability of the systems it manages. Organizations using Roxy-WI must urgently apply security patches to mitigate these threats.
