CVE-2020-9076Network attack vector

Malicious URL access via unverified message sender

Published Jun 15, 2020 · Updated Aug 4, 2024

Improper authentication in Huawei P30, P30 Pro, and Tony-AL00B firmware allows man-in-the-middle attackers to induce malicious URL access. The message-processing path does not properly verify the sender's identity before using the message to induce access to its URL. Exploitation requires device-network access and user interaction; affected builds precede 10.1.0.135(C00E135R2P11) on P30, 10.1.0.135(C00E135R2P8) or 10.1.0.135(C01E135R2P8) on P30 Pro, and 10.1.0.137(C00E137R2P11) on Tony-AL00B.
