CVE-2021-46811Network attack vector

CPLC disclosure via improper HwSEServiceAPP permissions

Published Jun 13, 2022 · Updated Aug 4, 2024

Improper permission management in Huawei HwSEServiceAPP allows attackers to read CPLC information via unspecified vectors. The service applies permissions incorrectly when mediating access to Card Production Life Cycle data, but Huawei has not disclosed the affected interface or permission check. Published records provide no exploit precondition beyond affected device software; the reported consequence is limited to CPLC information disclosure.
