Remote code execution via mimes deserialization
Published Nov 13, 2024 · Updated Nov 13, 2024
Deserialization in Backpack for Laravel FileManager before 3.0.9 allows remote attackers to execute code via a crafted mimes parameter. The inherited elFinder popup handler unserializes the request-controlled mimes value; the replacement controller first decrypts it and rejects tampering before serialization. Exploitation requires user interaction with a crafted popup request, and successful object injection executes code in the Laravel application context.
