CVE-2024-11120 is an OS Command Injection vulnerability identified in certain end-of-life GeoVision GV-VS12 devices. The root cause is improper neutralization of special elements in operating system commands (CWE-78), which allows unauthenticated remote attackers to inject and execute arbitrary system commands on the affected device. This vulnerability does not require any authentication or user interaction, making it highly exploitable over the network. The CVSS v3.1 base score is 9.8, indicating critical severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vulnerability affects the confidentiality, integrity, and availability of the device, potentially allowing attackers to take full control, disrupt services, or pivot into internal networks. Although the devices are end-of-life and no patches have been released, reports indicate that exploitation attempts have been observed in the wild. The affected product, GeoVision GV-VS12, is typically used in video surveillance and security monitoring, making the impact significant for organizations relying on these systems for physical security. The lack of patches and the critical nature of the flaw necessitate immediate mitigation steps to prevent compromise.

For European organizations, the exploitation of CVE-2024-11120 could lead to severe consequences including unauthorized access to surveillance systems, manipulation or deletion of video feeds, disruption of security monitoring, and potential lateral movement into corporate networks. This could compromise physical security, expose sensitive video data, and disrupt operational continuity. Organizations in sectors such as critical infrastructure, government, transportation, and large enterprises that rely on GeoVision GV-VS12 devices for surveillance are particularly vulnerable. The critical severity and ease of exploitation increase the risk of widespread attacks, potentially leading to data breaches, espionage, or sabotage. The unavailability of patches exacerbates the risk, forcing organizations to rely on compensating controls. The impact extends beyond the device itself, as compromised surveillance systems can serve as entry points for broader network intrusions.

Given the absence of official patches, European organizations should immediately implement network segmentation to isolate GeoVision GV-VS12 devices from critical networks and sensitive data. Disable all remote access interfaces to these devices, especially those exposed to the internet. Employ strict firewall rules to restrict inbound and outbound traffic to only trusted sources. Monitor network traffic for unusual command execution patterns or unexpected connections originating from these devices. Consider replacing end-of-life GV-VS12 devices with supported, patched alternatives as a long-term solution. If replacement is not immediately feasible, deploy intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting OS command injection patterns. Maintain up-to-date asset inventories to identify all affected devices. Conduct regular security audits and penetration tests focusing on surveillance infrastructure. Finally, educate security teams about this vulnerability to ensure rapid incident response if exploitation is detected.
