CVE-2022-40183 in VIDEOJET multi 4000
Summary
by MITRE • 10/27/2022
An error in the URL handler of the VIDEOJET multi 4000 may lead to a reflected cross site scripting (XSS) in the web-based interface. An attacker with knowledge of the encoder address can send a crafted link to a user, which will execute JavaScript code in the context of the user.

The vulnerability identified as CVE-2022-40183 resides within the VIDEOJET multi 4000 device family, specifically affecting its web-based interface through a flawed URL handling mechanism. This issue represents a classic reflected cross site scripting vulnerability that exploits how the system processes and renders user-supplied input from URLs. The VIDEOJET multi 4000 is a professional video encoding solution commonly deployed in broadcast and media production environments where secure handling of web interfaces is paramount for operational continuity and data protection.
The technical flaw manifests when the web interface fails to properly sanitize or encode user input received through URL parameters before rendering them in the browser context. This allows malicious actors to inject arbitrary JavaScript code that gets executed in the victim's browser when they click on a crafted link. The vulnerability specifically impacts the URL handler component, which processes incoming requests without adequate input validation or output encoding measures. According to CWE-79, this vulnerability maps directly to the classic reflected cross site scripting weakness where attacker-controlled data flows from a web server to a user's browser without proper sanitization, creating a persistent security risk for all users interacting with the affected web interface.
The operational impact of this vulnerability extends beyond simple script execution as it fundamentally compromises the security posture of the VIDEOJET multi 4000 system. An attacker who discovers the encoder address can craft malicious URLs that, when clicked by an authenticated user, execute arbitrary JavaScript code within the user's browser session. This opens the door to session hijacking, credential theft, data exfiltration, and potential lateral movement within the network environment. The attack vector is particularly concerning because it requires minimal reconnaissance - knowledge of the encoder's address is sufficient to craft effective malicious payloads, making it accessible to attackers with basic network discovery capabilities.
Mitigation strategies for this vulnerability should focus on immediate input validation and output encoding measures within the web application layer. The most effective approach involves implementing comprehensive parameter sanitization for all URL inputs, ensuring that any user-supplied data is properly encoded before being rendered in the browser context. Organizations should also consider implementing Content Security Policy headers to limit script execution capabilities and establish proper access controls to restrict unauthorized access to the web interface. Additionally, network segmentation and firewall rules should be configured to limit exposure of the VIDEOJET multi 4000 web interface to trusted internal networks only. This vulnerability aligns with ATT&CK technique T1566.001, which covers the use of spearphishing attachments and links, making it particularly dangerous in enterprise environments where users may be targeted through social engineering campaigns. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other networked devices and ensure comprehensive protection across the organization's attack surface.
