What is CVE-2021-47985?

The SAPSprint service in Brother's SAPSprint 7.60 product is susceptible to an unquoted service path vulnerability, which permits local attackers to gain elevated privileges. By placing a malicious executable within the Program Files directory, attackers can have this executable run with LocalSystem privileges once the SAPSprint service starts automatically. This can lead to unauthorized control over the system.

Affected Version(s)

SAPSprint 7.60

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
