Roxy-WI is a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. A command injection vulnerability exists in the log viewing functionality prior to version 8.2.8.2, which allows authenticated users to execute arbitrary system commands. The vulnerability is located in app/modules/roxywi/logs.py on line 87, where the grep parameter is used twice—once sanitized and once raw. This vulnerability is fixed in version 8.2.8.2.
The CVSS score for this vulnerability is 7.5, classified as high severity. This high score indicates a significant risk to organizations, particularly due to the potential for unauthorized command execution by authenticated users. Organizations should prioritize patching immediately.
The risk to organizations includes potential unauthorized access and control over affected servers, leading to significant operational disruptions. The exploitation of this vulnerability could have severe consequences, particularly in environments where Roxy-WI is deployed to manage critical services.
As of now, there are no known public exploits or proof-of-concept code available for this vulnerability. However, the nature of the vulnerability suggests that it could be a target for attackers, particularly in environments where Roxy-WI is widely used.
Given the high severity and potential impact, organizations utilizing Roxy-WI should take immediate steps to apply the necessary updates to mitigate this vulnerability.
Vulnerability Details
The vulnerability allows for command injection, classified under CWE-78. The CVSS v3.1 vector string is CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, reflecting an attack vector of network, high attack complexity, and low privileges required. User interaction is not needed, but the impact on confidentiality, integrity, and availability is high.
Technical Analysis
The root cause of this vulnerability lies in improper input sanitization in the log viewing functionality of Roxy-WI. The grep parameter's dual usage—once with sanitization and once raw—creates a pathway for command injection, enabling authenticated users to execute arbitrary commands on the server.
Attackers may leverage this vulnerability via the network, exploiting the high complexity of the attack to execute commands without requiring elevated privileges. No user interaction is needed, increasing the risk of exploitation.
The confidentiality, integrity, and availability impacts are all classified as high, indicating that successful exploitation could compromise sensitive information, alter critical operations, and disrupt service availability.
Risk & Impact Analysis
Organizations that deploy Roxy-WI face significant risks due to this vulnerability. The potential for command injection means that an attacker could gain unauthorized access to critical systems, leading to data breaches and operational disruptions.
The blast radius for this vulnerability is substantial, especially in environments where Roxy-WI is integrated into essential infrastructure. Consequently, organizations must assess their exposure and prioritize mitigation efforts.
With a CVSS score of 7.5, the urgency for remediation is high. Organizations should address this vulnerability in their priority patch cycle to prevent potential exploitation.
