Description from the CNA

SODOLA SL902-SWTGW124AS firmware before 200.2.12 contains a buffer overflow vulnerability that allows unauthenticated remote attackers to cause a denial of service by sending an oversized boundary value in the Content-Type header of a crafted POST request. Attackers can exploit the embedded HTTP server's multipart/form-data boundary parser to cause the device to become fully unresponsive — dropping all management access and traffic forwarding during its self-recovery cycle.
