Soumettre #902770: Fast FAC1900R 20190827_2.0.2 Stack-based Buffer Overflowinformation

TitreFast FAC1900R 20190827_2.0.2 Stack-based Buffer Overflow
DescriptionA stack-based buffer overflow vulnerability exists in the get_alias_name function within the firmware's uhttpd service (at offset 0x4049C9A8). The function copies the cloud_config.info.alias (device alias) field from an HTTP JSON request into a stack buffer using memcpy, but fails to perform an upper-bound check on the user-controllable string length. A specially crafted HTTP POST request can trigger this vulnerability.
