The vulnerability identified as CVE-2024-0054 affects AXIS network video cameras and security devices running AXIS OS firmware, specifically targeting three VAPIX API endpoints including local_list.cgi, create_overlay.cgi, and irissetup.cgi. This flaw represents a significant security weakness that could be exploited to perform resource exhaustion attacks against affected devices. The vulnerability stems from improper input validation within these API endpoints, allowing malicious actors to manipulate file globbing operations that process user-supplied parameters without adequate sanitization.
The technical implementation of this vulnerability demonstrates a classic case of improper input validation and insufficient parameter handling within web application interfaces. When these API endpoints receive requests containing specially crafted file globbing patterns, the system processes these patterns without proper bounds checking or sanitization mechanisms. This creates an opportunity for attackers to submit malicious input that causes the system to perform excessive file system operations or consume disproportionate computational resources. The vulnerability operates at the application layer and specifically impacts the device's ability to handle file system operations through the VAPIX API interface, making it particularly dangerous for networked security devices that must maintain consistent availability.
From an operational impact perspective, this vulnerability poses a substantial risk to security infrastructure deployments where AXIS cameras are used for surveillance and monitoring purposes. The resource exhaustion attack vector could potentially render affected devices unavailable for legitimate operations, creating denial of service conditions that compromise security monitoring capabilities. Attackers could exploit this vulnerability to repeatedly submit malicious file globbing patterns that cause the device to consume excessive CPU cycles, memory, or disk I/O resources, ultimately leading to system instability or complete device unavailability. This risk is particularly concerning for critical infrastructure deployments where continuous monitoring is essential for security operations.
The mitigation strategy for CVE-2024-0054 involves immediate deployment of patched AXIS OS firmware versions released by the vendor to address the specific file globbing vulnerabilities in the affected VAPIX API endpoints. Organizations should conduct comprehensive inventory assessments to identify all affected AXIS devices within their network infrastructure and prioritize patching activities based on risk assessment. Network segmentation and access controls should be implemented to limit exposure of these devices to untrusted networks, while monitoring systems should be deployed to detect anomalous API access patterns that might indicate exploitation attempts. The vulnerability aligns with CWE-94, which describes improper validation of a file path or name, and represents a potential pathway for attackers to execute resource exhaustion attacks through the MITRE ATT&CK framework's resource exhaustion techniques. Regular security assessments and vulnerability scanning should be conducted to ensure ongoing protection against similar vulnerabilities in networked security devices.
