Service disruption via JSON parser out-of-bounds read
Published Mar 12, 2020 · Updated Aug 4, 2024
Out-of-bounds read in the JSON parser of Huawei USG6000V allows remote attackers with network access to interrupt service. A logic error makes the parser read beyond a buffer boundary while processing untrusted JSON, but Huawei has not disclosed the specific request field or function. Exploitation requires no authentication or user interaction, but the target must be reachable on the affected product's network; the documented consequence is service disruption only.
