CVE-2026-1419 is a command injection vulnerability identified in the D-Link DCS700l IP camera firmware version 1.03.09. The vulnerability resides in the Web Form Handler component, specifically in the /setDayNightMode endpoint, where the LightSensorControl parameter is improperly sanitized. An attacker can remotely manipulate this argument to inject arbitrary commands into the underlying operating system, potentially gaining control over the device. The vulnerability does not require authentication or user interaction, making it remotely exploitable over the network. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no authentication required (AT:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently active in the wild, the public availability of exploit code increases the risk of future attacks. The device’s role as an IP camera means exploitation could lead to unauthorized surveillance, device manipulation, or pivoting into internal networks. No official patches or vendor advisories have been published yet, increasing the urgency for organizations to apply compensating controls.

For European organizations, exploitation of this vulnerability could lead to unauthorized remote control of D-Link DCS700l cameras, resulting in privacy breaches through unauthorized video access or manipulation. Attackers could disrupt camera functionality, impacting physical security monitoring and surveillance operations. Compromise of these devices could also serve as a foothold for lateral movement within corporate or critical infrastructure networks, potentially leading to broader network compromise. Given the widespread use of IP cameras in sectors such as government, transportation, healthcare, and manufacturing across Europe, the impact could be significant. The partial impact on confidentiality, integrity, and availability means sensitive visual data could be exposed or altered, and device availability could be disrupted, affecting security operations. The medium severity rating suggests a moderate but tangible risk, especially if exploited in targeted attacks against high-value assets or critical infrastructure.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include disabling remote access to the DCS700l cameras from untrusted networks and restricting management interfaces to trusted internal networks only. Network segmentation should be enforced to isolate IP cameras from critical systems and sensitive data environments. Employ strict firewall rules to limit inbound and outbound traffic to the devices. Monitor network traffic and device logs for unusual commands or behavior indicative of exploitation attempts. Consider replacing affected devices with updated models or firmware once patches are released. Additionally, implement strong physical security controls to prevent unauthorized device tampering. Regularly review and update device configurations to minimize exposed attack surfaces. Finally, maintain awareness of vendor advisories for timely patch deployment.
