A Use After Free vulnerability on UniFi Protect Cameras could allow a Remote Code Execution (RCE) by a malicious actor with access to UniFi Protect Cameras management network.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
