CVE-2020-9253Network attack vector

Service interruption via crafted-packet stack overflow

Published Dec 27, 2024 · Updated Dec 27, 2024

Stack-based buffer overflow in Huawei Lion-AL00C before 10.1.0.150(C00E136R5P3) allows remote attackers to interrupt service. Insufficient packet verification permits a crafted packet to overflow the stack, but Huawei does not identify the affected component or field. Exploitation requires tricking a user into clicking a website; the vendor reports information tampering and availability impact.
