CVE-2023-6260

Physical-security bypass via Web UI command injection

Published Feb 19, 2024 · Updated Aug 2, 2024

OS command injection in Brivo ACS100 and ACS300 firmware before 6.2.4.3 allows attackers to read sensitive device data through the web UI. The advisory identifies the Web UI as the injection surface but does not disclose the affected request, parameter, or command-building operation. Exploitation requires authenticated adjacent-network access to an ACS100 or authenticated physical access to an ACS300, and command execution can bypass physical-security functions.
