CVE-2023-0011: U-Blox Toby-l200 Firmware

Medium severity, CVSS 6.8. EPSS: 0.5% chance of exploitation in the next 30 days.

A flaw in the input validation in TOBY-L2 allows a user to execute arbitrary operating system commands using specifically crafted AT commands. This vulnerability requires physical access to the serial interface of the module or the ability to modify the system or software which uses its serial interface to send malicious AT commands. Exploitation of the vulnerability gives full administrative (root) privileges to the attacker to execute any operating system command on TOBY-L2 which can lead to modification of the behavior of the module itself as well as the components connected with it (depending on its rights on other connected systems). It can further provide the ability to read system level files and hamper the availability of the module as well.. This issue affects TOBY-L2 series: TOBY-L200, TOBY-L201, TOBY-L210, TOBY-L220, TOBY-L280.
