CVE-2026-109439

Lantronix XPress-DR 8.1.0.0 Unauthenticated Configuration Write via UDP 30718

Lantronix XPress-DR and XPress-DR-I (CoBos-family) firmware through 8.1.0.0 contains a missing authentication vulnerability that allows remote attackers to read and persistently overwrite device configuration by sending crafted frames to the unauthenticated UDP configuration protocol on port 30718. Attackers can send a type 0xF8 query to read live configuration data and a type 0xFD frame with exactly 0x78 body bytes to rewrite the device IP address and serial-channel forwarding records, causing changes to commit to EEPROM and persist across reboots. The XPress-DR product series reached end-of-life/end-of-support in February 2025.

CVE-2026-84409

Lantronix G520 Series Cellular Gateway Cross-site Scripting

The device's update mechanism retrieves metadata for software updates over an unencrypted HTTP connection and stores portions of that metadata for later use. A management interface subsequently returns this stored value in a JSON response, and the web interface responsible for displaying update information inserts that value directly into the page as HTML. This behavior allows attacker‑controlled metadata to be interpreted as script content. In addition, the same authenticated origin provides an interface capable of executing system‑level commands with root privileges. An attacker able to influence update metadata could exploit these conditions to execute arbitrary code within the administrative context of the device.

CVE-2026-91191

Lantronix G520 Series Cellular Gateway Improper Verification of Cryptographic Signature

The device's update mechanism includes conditions that allow unauthorized software packages to be accepted as authentic. During the boot process, the stock done function disables signature verification in the OPKG configuration before restoring optional packages from a writable, unsigned feed. Separately, the publicly distributed SDK contains the production private key whose corresponding public key is trusted by both stable and beta firmware builds. Either issue undermines package authenticity, and together they allow an attacker to provide packages that appear valid to the system. Even if signature enforcement is restored, the exposed production key enables an attacker to generate signatures that the device will continue to trust. An attacker who can supply a malicious package may be able to execute arbitrary code with root privileges during installation.

CVE-2026-80151

Lantronix Autonomous Out-of-Band Devices OS Command Injection via set nfs download

Lantronix SLC8000 before firmware v9.7.0.3, 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 command injection vulnerability that allows authenticated attackers with the services permission to execute arbitrary shell commands as root by exploiting the set nfs download command that passes unsanitized user input to a system() call. Attackers with the services permission can authenticate to the terminal or CLI interface and inject malicious commands through the unsanitized parameter to achieve complete loss of confidentiality, integrity, and availability on the affected device and potentially impact downstream serial-attached devices.

Attackers can authenticate as any user to the terminal or CLI interface and supply an oversized input to trigger the overflow, potentially achieving complete loss of confidentiality, integrity, and availability on the affected device and impacting downstream serial-attached devices.

CVE-2026-80156

Lantronix Autonomous Out-of-Band Devices Arbitrary File Write via Upload Filename Validation Bypass

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.

Lantronix Autonomous Out-of-Band Devices Unauthenticated Authentication Bypass via snprintf Path Truncation

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 an authentication bypass vulnerability in the web management portal upload endpoint that allows unauthenticated attackers to read sensitive configuration files and upload files to arbitrary filesystem locations, leading to remote code execution. The web configuration server constructs the session cookie file path using snprintf with a fixed-size buffer; by supplying a cookie value of a specific length an attacker causes the path to truncate at the required delimiter and leverages path traversal to redirect authentication validation to an arbitrary on-disk file such as the local user database, bypassing all session checks. 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.

CVE-2026-80154

Lantronix Autonomous Out-of-Band Devices Predictable Session Token with Validation Bypass

All firmware versions of Lantronix SLC8000, SLC9000, EMG8500, EMG7500, SLB882, SLCx-03, and SLCx-02 contain an authentication bypass vulnerability in the web management portal that allows unauthenticated attackers to derive valid session tokens of logged-in users and bypass source IP and User-Agent validation. Session tokens are generated deterministically from the device model and the current time at one-second resolution, resulting in a small enumerable set of possible active tokens. Attackers can construct a crafted URI that exploits file extension handling in the web server path routing to bypass per-session source-address validation, then use a derived token from a different source address to gain elevated privileges on the affected device and potentially impact downstream serial-attached devices.

The custom shellinaboxd uses the rooturl parameter from the web connection to determine its own IP address; by modifying this parameter an attacker redirects the Telnet terminal connection to an arbitrary host or IP. Attackers can use this capability to enumerate or communicate with internal network endpoints that would otherwise be inaccessible.

Lantronix EDS5000, G520, and X300 OS Command Injection

An issue was discovered in Lantronix EDS5000 2.1.0.0R3. The HTTP RPC module executes a shell command to write logs when user's authentication fails. The username is directly concatenated with the command without any sanitization. This allow attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges.
