Naxclow IoT Platform Insertion of sensitive information into Externally-Accessible file or directory

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.

Cisco IOS XE ROM Monitor Software for Catalyst Switches Information Disclosure Vulnerability

A vulnerability in the password-recovery disable feature of Cisco IOS XE ROM Monitor (ROMMON) Software for Cisco Catalyst Switches could allow an unauthenticated, local attacker to recover the configuration or reset the enable password. This vulnerability is due to a problem with the file and boot variable permissions in ROMMON. An attacker could exploit this vulnerability by rebooting the switch into ROMMON and entering specific commands through the console. A successful exploit could allow the attacker to read any file or reset the enable password.
