ipc-d250_firmware: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2024-35343 is a critical-severity exposure of sensitive information to an unauthorized actor vulnerability in ipc-d250_firmware from Anpviz, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected ipc-d250_firmware versions: 3.2.2.2 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.47% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of ipc-d250_firmware you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Certain Anpviz products allow unauthenticated users to download arbitrary files from the device's filesystem via a HTTP GET request to the /playback/ URI. This affects 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 (IP Cameras) firmware v3.2.2.2 and lower and possibly more vendors/models of IP camera.

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.
