CyberRota Analysis
AI-GeneratedThe web management portal of Lantronix SLC8000, EMG8500/EMG7500, and SLB882/SLCx-03/SLCx-02 devices prior to specified firmware versions is vulnerable to a path traversal flaw that allows authenticated attackers to write arbitrary data to any location on the device's filesystem, resulting in remote code execution. This critical vulnerability can lead to a complete loss of confidentiality, integrity, and availability, potentially affecting downstream connected devices. Organizations using these products should prioritize patching to mitigate the risk of exploitation.

Original NVD Description
Lantronix SLC8000 before firmware v9.7.0.5, SLC9000 before firmware v9.7.0.2, EMG8500/EMG7500 before firmware v9.7.0.1, and all firmware versions of SLB882/SLCx-03/SLCx-02 contain a path traversal vulnerability in the web management portal upload endpoint that allows authenticated attackers to write arbitrary data to any location on the device's filesystem, leading to remote code execution. The upload filename validation strips backslash characters but does not subsequently check for forward slashes when a backslash is detected; by supplying a filename containing both characters an attacker writes outside the intended upload directory to any writable path. Attackers can use this vulnerability to achieve complete loss of confidentiality, integrity, and availability on the affected device and potentially impact downstream serial-connected devices.
