Summary

ZTE Z80 Ultra, in the GEN_ZTE_PQ85A01V1.0.0B27 and prior released versions, has a permission verification defect in a system interface. The interface lacks necessary access control, so an attacker can read relevant information by reflectively invoking it. Exploitation requires user interaction and an adjacent network position, and the impact is limited to confidentiality. The weakness is CWE-269, Improper Privilege Management.
