Comprehensive Technical Analysis of EUVD-2024-35292

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2024-35292 involves a hardcoded cryptographic key stored in the firmware of certain Anpviz IP camera models. This issue affects a wide range of devices, including but not limited to IPC-D250, IPC-D260, IPC-B850, IPC-D850, IPC-D350, IPC-D3150, IPC-D4250, IPC-D380, IPC-D880, IPC-D280, IPC-D3180, MC800N, YM500L, YM800N_N2, YMF50B, YM800SV2, YM500L8, and YM200E10. The affected firmware versions are v3.2.2.2 and lower.

Severity Evaluation:

• Base Score: 9.9 (Critical)
• Base Score Version: CVSS:3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

The high base score of 9.9 indicates a critical vulnerability. The CVSS vector breakdown shows that the vulnerability can be exploited over the network (AV:N), requires low complexity (AC:L), and low privileges (PR:L). It does not require user interaction (UI:N), affects the confidentiality, integrity, and availability of the system (C:H/I:H/A:H), and has a high impact on the scope (S:C).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Remote Exploitation: An attacker can exploit this vulnerability over the network, making it accessible from anywhere with network access.
2. Firmware Extraction: The hardcoded cryptographic key can be extracted from the firmware, allowing attackers to decrypt communications and potentially gain unauthorized access.
3. Man-in-the-Middle (MitM) Attacks: With the cryptographic key compromised, attackers can intercept and manipulate data transmitted between the IP camera and its management systems.

Exploitation Methods:

1. Firmware Analysis: Attackers can analyze the firmware to extract the hardcoded key.
2. Network Sniffing: Using the extracted key, attackers can decrypt network traffic to and from the IP camera.
3. Unauthorized Access: With the key, attackers can gain administrative access to the device, leading to further exploitation.

3. Affected Systems and Software Versions

Affected Systems:

• Anpviz IP camera models: IPC-D250, IPC-D260, IPC-B850, IPC-D850, IPC-D350, IPC-D3150, IPC-D4250, IPC-D380, IPC-D880, IPC-D280, IPC-D3180, MC800N, YM500L, YM800N_N2, YMF50B, YM800SV2, YM500L8, and YM200E10.
• Firmware versions: v3.2.2.2 and lower.

Potentially Affected Systems:

• Other vendors/models of IP cameras that may use similar firmware or have similar vulnerabilities.
