Unauthorized friend addition via undisclosed logic flaw
Published Aug 23, 2021 · Updated Aug 3, 2024
Logic flaw in Huawei Honor Little K 2 1.0.0.608 allows remote attackers on the device network to add friends without device prompts. Huawei identifies insufficient security design and unspecified operations, but does not disclose the request path, handler, or failed authorization check. Exploitation requires access to the target device network and changes its social relationships without approval; the Chinese advisory also reports that users can be trapped in groups.
