Summary
CVE-2026-56718 is a path traversal vulnerability (CWE-22) in the jdbhttpd web service embedded in AJCloud AJY IPC firmware. It allows unauthenticated remote attackers to read arbitrary files from the device filesystem with root privileges by sending crafted HTTP requests to the device’s web server on port 80. Exploitation can expose RTSP stream credentials, Wi-Fi SSID/PSK, device serial numbers, and cloud binding parameters, making it a high-severity information disclosure issue (CVSS 8.7) affecting internet-exposed IP cameras.
Technical details
- Root cause: The
jdbhttpdweb service fails to properly sanitize file paths supplied in HTTP request URIs, allowing directory traversal sequences to escape the intended web root. - Trigger conditions: An attacker sends a specially crafted HTTP request containing path traversal sequences to the device’s web service on TCP port 80.
- Attack vector: Network — no authentication and no user interaction is required to exploit the vulnerability.
- Impact: Arbitrary file read with root-level filesystem access, enabling disclosure of RTSP credentials (in plaintext), Wi-Fi credentials, device serial numbers, and cloud binding parameters — information that can facilitate further compromise of the device, the local network, or the associated cloud account.
Affected software
- AJCloud AJY IPC Firmware — all versions prior to 01.10715.11.37
Severity
- CVSS v3.1 Base Score: 7.5 (High) — Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N - CVSS v4.0 Score: 8.7 (High) — Vector:
CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
Mitigation and recommended actions
- Immediate: Upgrade affected AJY IPC devices to firmware version 01.10715.11.37 or later, where the path traversal issue in
jdbhttpdis addressed. - If patching is not immediately possible:
- Do not expose the device’s web service (port 80) directly to the internet; restrict access to trusted internal networks only.
- Place affected cameras behind a firewall or VPN and block inbound access to port 80 from untrusted sources.
- Change default RTSP and Wi-Fi credentials, and monitor for unusual access to the device’s HTTP service.
- Inventory internet-facing IP camera deployments to identify devices running vulnerable AJCloud AJY firmware.
