CVE-2023-37238Network attack vector

Wireless projection alteration via incomplete permission checks

Published Jul 6, 2023 · Updated Nov 19, 2024

Authorization flaw in Huawei HarmonyOS 3.0.0 and 3.1.0 and EMUI 13.0.0 allows attackers to alter wireless projection via API access. The wireless projection module incompletely verifies an app's permission before allowing access to a restricted API. Exploitation requires an app to invoke the API, and Huawei limits the disclosed consequence to unspecified changes in wireless projection features.
