CVE-2020-1880

Device abnormality via insufficiently validated file field

Published Apr 27, 2020 · Updated Aug 4, 2024

Denial of service in Huawei Lion-AL00C before 10.0.0.205(C00E202R7P2) allows attackers to cause abnormal device operation via a crafted file. The file-execution path insufficiently validates an unspecified field in the crafted file before using its value; Huawei has not identified the field or parser. Exploitation requires an attacker to trick a user into executing the file, and the documented consequence is limited to abnormal device operation.
