Denver SHO-110 - Unauthenticated Snapshot Access via Secondary HTTP Service

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2021-4469. PoCs published by Ivan Nikolsky.

AI-analyzed exploit summary This exploit demonstrates an unauthenticated snapshot retrieval vulnerability in Denver SHO-110 IP Camera via an exposed endpoint on port 8001. The backdoor allows attackers to bypass authentication and capture snapshots, potentially reconstructing the camera stream.

Description

Denver SHO-110 IP cameras expose a secondary HTTP service on TCP port 8001 that provides access to a '/snapshot' endpoint without authentication. While the primary web interface on port 80 enforces authentication, the backdoor service allows any remote attacker to retrieve image snapshots by directly requesting the 'snapshot' endpoint. An attacker can repeatedly collect snapshots and reconstruct the camera stream, compromising the confidentiality of the monitored environment.
