Summary
by MITRE • 06/28/2024
A vulnerability regarding improper neutralization of special elements used in an OS command ('OS Command Injection') is found in the IP block functionality. This allows remote authenticated users with administrator privileges to execute arbitrary commands via unspecified vectors. The following models with Synology Camera Firmware versions before 1.0.7-0298 may be affected: BC500 and TC500.

This vulnerability represents a critical operating system command injection flaw that specifically targets the IP block functionality within Synology Camera firmware versions prior to 1.0.7-0298. The issue stems from inadequate sanitization of user-supplied input that flows into operating system commands, creating a pathway for malicious execution. The vulnerability classification aligns with CWE-77 and CWE-88, which detail improper neutralization of special elements in command contexts and the improper neutralization of special elements used in command injection attacks respectively. Attackers exploiting this weakness can leverage the OS command injection vector to execute arbitrary code on the affected devices.
The technical implementation of this vulnerability occurs within the IP block functionality of the camera systems, where user-provided parameters are not properly validated or escaped before being incorporated into system commands. This allows authenticated administrators with appropriate privileges to inject malicious commands that bypass normal security controls. The attack surface is particularly concerning because it requires only administrative access, which is often obtained through legitimate administrative functions. The exploitation process typically involves crafting specially formatted input that gets processed by the vulnerable command execution mechanism, ultimately leading to arbitrary code execution on the target device.
From an operational perspective, this vulnerability poses significant risks to network security infrastructure, particularly in environments where Synology cameras are deployed for surveillance and monitoring purposes. The affected BC500 and TC500 models represent a substantial portion of the installed base that requires immediate attention. The potential impact includes complete system compromise, data exfiltration, lateral movement within the network, and disruption of security monitoring capabilities. This vulnerability directly maps to ATT&CK technique T1059.001 for command and scripting interpreter and T1068 for exploit for privilege escalation, making it a critical concern for security operations teams.
Organizations should prioritize immediate firmware updates to version 1.0.7-0298 or later to remediate this vulnerability. Network segmentation and access controls should be implemented to limit administrative access to these devices, while monitoring systems should be configured to detect unusual command execution patterns. Regular security assessments of networked camera systems are essential to identify similar vulnerabilities in other networked devices. Additionally, implementing proper input validation mechanisms and adopting defense-in-depth strategies will help mitigate the risk of similar command injection vulnerabilities in the broader network infrastructure. The vulnerability demonstrates the critical importance of secure coding practices and proper input sanitization in embedded systems and IoT devices.
