Security readout for executives and security teams
Plain-English summary
This issue affects the Tenda AC23 firmware build V16.03.07.45_cn named in the CVE. A network attacker may be able to trigger a stack overflow in wireless repeater settings handling, potentially compromising the router. The sources do not confirm a vendor fix or active exploitation.
Executive priority
Prioritize validation for any exposed Tenda AC23 routers. There is no cited active exploitation, but the severity is critical because the reported condition is unauthenticated, network-reachable, and could fully compromise device confidentiality, integrity, and availability.
Technical view
CVE-2022-43104 is a CWE-787 out-of-bounds write in Tenda AC23 V16.03.07.45_cn. The flaw is reported in fromSetWirelessRepeat, involving the wpapsk_crypto parameter. CVSS 3.1 is 9.8: network-accessible, low complexity, no privileges, no user interaction, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely where Tenda AC23 devices run firmware V16.03.07.45_cn. Risk increases if device management or wireless repeater configuration paths are reachable from untrusted networks. The source bundle does not identify other affected versions or products.
Exploitation context
The bundle does not show CISA KEV inclusion, and no cited source states active exploitation. The CVSS vector indicates unauthenticated network exploitation may be possible if the affected interface is reachable, but the provided evidence is limited to the public CVE metadata and research reference.
Researcher notes
Evidence is sparse. The public record names Tenda AC23 V16.03.07.45_cn, wpapsk_crypto, and fromSetWirelessRepeat. Do not assume other firmware builds are affected without vendor or researcher confirmation. No patch details are present in the provided sources.
Mitigation direction
- Inventory Tenda AC23 devices and identify firmware versions.
- Check Tenda guidance for fixed firmware or official mitigations.
- Restrict router management access to trusted networks only.
- Disable unnecessary remote administration exposure where present.
- Replace or isolate affected devices if no supported fix exists.
Validation and detection
- Confirm whether any Tenda AC23 runs V16.03.07.45_cn.
- Review management-plane exposure from internet and guest networks.
- Check firewall rules limiting access to router administration interfaces.
- Look for vendor advisories or firmware release notes addressing CVE-2022-43104.
- Monitor router logs for crashes or unexpected configuration changes.
