CVE-2025-52600 is a vulnerability identified in the Hanwha Vision QNV-C8012 camera video analytics product, stemming from improper input validation (CWE-20). This flaw allows an attacker to craft malicious inputs that the system fails to properly sanitize or verify, leading to the potential execution of specific commands on the host PC where the analytics software runs. The vulnerability affects firmware versions prior to 2.22.05. Exploitation requires the attacker to have high privileges (PR:H) and partial user interaction (UI:P), indicating that some level of authentication and user involvement is necessary. The CVSS 4.0 base score of 5.2 reflects a medium severity, with network attack vector (AV:N), low attack complexity (AC:L), and no impact on confidentiality, integrity, or availability (C:N, I:N, A:N). The scope is high (S:H), meaning the vulnerability affects components beyond the initially vulnerable component, and the security requirements for confidentiality, integrity, and availability are high (SC:H, SI:H, SA:H). No known exploits have been reported in the wild, but the vendor has released firmware patches to remediate the issue. The vulnerability is particularly relevant for Industrial Control Systems (ICS) and OT/IoT environments where these cameras are deployed for video analytics, as unauthorized command execution could lead to operational disruptions or lateral movement within networks.

For European organizations, especially those in critical infrastructure sectors such as manufacturing, energy, transportation, and public safety, this vulnerability poses a risk of unauthorized command execution on host systems running the vulnerable Hanwha Vision QNV-C8012 cameras. While the direct impact on confidentiality, integrity, and availability is rated as none, the ability to execute commands could enable attackers to pivot within networks, disrupt video analytics operations, or interfere with monitoring capabilities. This could degrade situational awareness and response times in security-sensitive environments. Given the reliance on video analytics in many European industrial and public safety contexts, exploitation could have cascading effects on operational technology environments. The requirement for high privileges and user interaction reduces the likelihood of widespread exploitation but does not eliminate the risk, particularly from insider threats or targeted attacks. The absence of known exploits in the wild provides a window for proactive mitigation before active exploitation occurs.

European organizations should immediately verify the firmware version of all Hanwha Vision QNV-C8012 devices and upgrade to version 2.22.05 or later as provided by the vendor. Network segmentation should be enforced to isolate camera systems from critical IT and OT networks, limiting the potential for lateral movement if exploitation occurs. Access controls must be tightened to ensure that only authorized personnel have high-level privileges required to exploit this vulnerability. Multi-factor authentication (MFA) should be implemented for all administrative access to camera management interfaces. Monitoring and logging of command execution and user interactions on host PCs running the analytics software should be enhanced to detect any anomalous activities. Organizations should also conduct regular vulnerability assessments and penetration testing focused on ICS/OT environments to identify and remediate similar input validation issues. Finally, incident response plans should be updated to include scenarios involving video analytics system compromise.
