CVE-2025-5875Public exploitNetwork attack vector

Memory corruption via oversized text argument

Published Jun 9, 2025 · Updated Jun 12, 2025

Buffer overflow in /bin/main in TP-LINK TL-IPC544EP-W4 1.0.9 Build 240428 Rel 69493n allows remote authenticated users to corrupt memory. The sub_69064 routine fails to constrain attacker-controlled text to its destination buffer before processing it. Low-privilege network access is required; successful exploitation exposes camera data and operation to unauthorized access, alteration, or interruption.
