CP-VNR-3104, CP-VNR-3108, CP-VNR-3208: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2023-3705 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in CP-VNR-3104, CP-VNR-3108, CP-VNR-3208 from Aditya Infotech Limited, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version B3223P22C02424 as the first without the flaw, so updating CP-VNR-3104, CP-VNR-3108, CP-VNR-3208 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.12% chance of exploitation within 30 days, higher than 67% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update CP-VNR-3104, CP-VNR-3108, CP-VNR-3208 to B3223P22C02424 or a later version.
- Update cp-vnr-3104 to b3223P22C02424 or a later version.
- Update cp-vnr-3108 to b3223P22C02424 or a later version.

Official description
The vulnerability exists in CP-Plus NVR due to an improper input handling at the web-based management interface of the affected product. An unauthenticated remote attacker could exploit this vulnerability by sending specially crafted HTTP requests to the vulnerable device. Successful exploitation of this vulnerability could allow the remote attacker to obtain sensitive information on the targeted device.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
