CVE-2025-53702 in VS-IPC1002
Summary
by MITRE • 10/23/2025
Vilar VS-IPC1002 IP cameras are vulnerable to DoS (Denial-of-Service) attacks. An unauthenticated attacker on the same local network might send a crafted request to /cgi-bin/action endpoint and render the device completely unresponsive. A manual restart of the device is required. The vendor did not respond in any way. Only version 1.1.0.18 was tested, other versions might be vulnerable as well.

The Vilar VS-IPC1002 IP camera represents a critical security vulnerability that exposes devices to unauthorized denial-of-service attacks within local network environments. This vulnerability specifically targets the device's /cgi-bin/action endpoint, which serves as a communication interface for handling various camera functions and configurations. The flaw allows unauthenticated attackers to exploit the device's processing logic through carefully crafted requests that trigger system instability. The vulnerability is particularly concerning because it operates entirely within the local network boundary, meaning attackers do not require external network access or complex reconnaissance to exploit the weakness. The device's response to malicious input results in complete system unresponsiveness, effectively rendering the camera inoperable until manual intervention occurs through physical device restart procedures.
The technical nature of this vulnerability aligns with common software design flaws that lack proper input validation and error handling mechanisms. When the /cgi-bin/action endpoint receives malformed or unexpected request parameters, the system fails to properly sanitize or reject these inputs, leading to a complete system crash or hang condition. This behavior indicates insufficient defensive programming practices and suggests that the device's web server implementation does not adequately protect against malformed HTTP requests or buffer overflows that could occur during request processing. The vulnerability's classification as a denial-of-service condition reflects the system's inability to maintain operational continuity under malicious input conditions, which represents a fundamental failure in system resilience and fault tolerance design principles.
From an operational perspective, this vulnerability creates significant risk for organizations deploying Vilar VS-IPC1002 cameras in security-critical environments where continuous monitoring is essential. The requirement for manual device restart following exploitation creates a potential window of security coverage loss that attackers can exploit strategically. Network administrators face the challenge of maintaining camera availability without immediate remote recovery mechanisms, potentially leaving surveillance gaps during critical periods. The local network attack vector means that any device connected to the same network segment could potentially exploit this vulnerability, including compromised endpoints, insider threats, or attackers who have gained local network access through other means. This exposure level makes the vulnerability particularly dangerous in enterprise environments where network segmentation may not be comprehensive enough to isolate all camera devices.
The vulnerability's impact extends beyond simple service disruption to potentially compromise overall security infrastructure integrity. When cameras become unresponsive, the organization loses real-time visual monitoring capabilities, creating blind spots in their security posture that attackers can exploit. The lack of vendor response to this vulnerability indicates a potential gap in the device's security support lifecycle, leaving users without official patches or mitigation guidance. This situation is particularly concerning given that the vulnerability affects a specific firmware version 1.1.0.18, suggesting that the issue may be present in other versions as well, though untested. Organizations should consider implementing network-based access controls to limit exposure and potentially disable the affected endpoint until a security patch is available. The vulnerability also demonstrates the importance of proper input validation and robust error handling in embedded systems, as outlined in security standards such as those referenced in the CWE (Common Weakness Enumeration) catalog for improper input validation and resource management failures. From an attack framework perspective, this vulnerability could be categorized under ATT&CK techniques related to service stoppage and system resource exhaustion, potentially enabling attackers to achieve broader operational disruption goals.
