CVE-2017-15325 — Huawei Prague-Al00A Firmware security vulnerability

High CVSS 9.3

The Bdat driver of Prague smart phones with software versions earlier than Prague-AL00AC00B211, versions earlier than Prague-AL00BC00B211, versions earlier than Prague-AL00CC00B211, versions earlier than Prague-TL00AC01B211, versions earlier than Prague-TL10AC01B211 has integer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP and execute it as a specific privilege; the APP can then send a specific parameter to the driver of the smart phone, causing arbitrary code execution.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
