CVE-2024-52544Public exploitNetwork attack vector

Unauthenticated code execution via unchecked login fields

Published Dec 3, 2024 · Updated Sep 5, 2025

Stack-based buffer overflow in Lorex 2K Indoor Wi-Fi Security Camera before 2.800.0000000.8.R.20241111 allows remote attackers to execute code. The unauthenticated DP Service login handler copies double-ampersand-delimited username and password values into separate 128-byte stack buffers with memcpy without checking either length. Network access to the custom DP protocol on TCP port 3500 is sufficient to overwrite a saved return address and redirect execution.
