Detailsinfo

A vulnerability, which was classified as problematic, has been found in Naxclow Smart Doorbell X3, X Smart Home, V720 and ix cam (version now known). Affected by this issue is some unknown processing of the component Setting Handler. The manipulation with an unknown input leads to a file information disclosure vulnerability. Using CWE to declare the problem leads to CWE-538. The product places sensitive information into files or directories that are accessible to actors who are allowed to have access to the files, but not to the sensitive information. Impacted is confidentiality. CVE summarizes:

During WiFi association, Naxclow device firmware prints the host network’s SSID, PSK, and negotiated WPA keys in cleartext to an exposed UART console on production hardware. The UART pads are labeled, run with default serial settings, and drop to an interactive RT-Thread shell that permits arbitrary memory reads, enabling full firmware extraction. An attacker with brief physical access, common for outdoor-mounted devices, can therefore recover WiFi credentials and bootstrap firmware-side attacks.

The weakness was disclosed by Temuri Takalandze as icsa-26-162-02. The advisory is shared for download at cisa.gov. This vulnerability is handled as CVE-2026-50099 since 06/08/2026. The exploitation is known to be easy. The attack needs to be approached locally. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1083.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
