CVE-2025-69986 is a critical buffer overflow vulnerability identified in the ONVIF GetStreamUri function of LSC Indoor Camera firmware version 7.6.32. The vulnerability stems from the failure of the application to properly validate the length of the Protocol parameter inside the Transport element of a SOAP request. ONVIF (Open Network Video Interface Forum) is a standard protocol widely used for IP-based security cameras to communicate streaming information. By sending a specially crafted SOAP request containing an excessively long protocol string, an attacker can overflow the stack buffer and overwrite the return instruction pointer (RIP). This memory corruption can cause the device to crash, resulting in Denial of Service (DoS), or potentially allow the attacker to execute arbitrary code remotely with the privileges of the ONVIF service. The vulnerability is exploitable remotely without authentication, as ONVIF services are often exposed on local networks or sometimes on the internet. No official patch or version information beyond 7.6.32 is provided, and no known exploits have been reported in the wild as of the publication date. The lack of a CVSS score requires an assessment based on the technical details, which indicate a high-severity risk due to the potential for RCE and device disruption. This vulnerability highlights the risks of insufficient input validation in network-facing IoT devices, especially those used in security-critical environments.

The impact of CVE-2025-69986 is significant for organizations deploying LSC Indoor Cameras, particularly in security, surveillance, and critical infrastructure monitoring. Successful exploitation can lead to device crashes causing Denial of Service, disrupting video surveillance and potentially creating blind spots in security coverage. More critically, Remote Code Execution allows attackers to gain control over the affected camera, which could be leveraged to pivot into broader network environments, exfiltrate sensitive video feeds, or deploy malware. Given that ONVIF is a common protocol in IP cameras, the vulnerability could be exploited remotely without authentication if the ONVIF service is exposed, increasing the attack surface. This poses risks to enterprises, government agencies, and critical infrastructure operators relying on these cameras for physical security. The inability to detect or prevent such attacks could lead to operational disruptions, privacy violations, and increased risk of further network compromise.

To mitigate CVE-2025-69986, organizations should first verify if their LSC Indoor Cameras are running the vulnerable firmware version 7.6.32 and restrict network access to ONVIF services. Network segmentation should be implemented to isolate camera devices from critical network segments and limit exposure to untrusted networks, including the internet. Deploy firewall rules to block unauthorized access to ONVIF ports (typically TCP 80, 443, or 8899) from outside trusted networks. Monitor network traffic for anomalous SOAP requests with unusually long Protocol parameters or malformed ONVIF messages. Engage with the vendor to obtain firmware updates or patches addressing this vulnerability. If patches are unavailable, consider disabling ONVIF services if not required or replacing affected devices with more secure alternatives. Additionally, implement intrusion detection systems (IDS) capable of detecting buffer overflow attempts targeting ONVIF services. Regularly audit device configurations and maintain an inventory of IoT devices to ensure timely response to emerging vulnerabilities.
