Summary description

Lantronix EDS5000 contains a code injection vulnerability that could allow attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges.

Required action

Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

Technical description

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.

———Wheels CLI 4.0.0 through 4.1.1 insufficiently validates or escapes caller-supplied values and package contents. Deploy release/version/rollback values can execute shell commands on deploy hosts as the SSH user and on the CI runner during builds. Package removal and destroy paths can delete unintended files; package extraction can overwrite other vendor files; generator names can write outside the project or inject executable CFML into generated code. Inputs may originate from CI variables, branch names, packages or an AI agent using the CLI's MCP tools. Also relevant are unencoded display properties in generated scaffold show views since 4.1.0 and in generated admin views, permitting stored XSS, and stale process-ID handling in RustCFML server commands that can terminate an unrelated process. This is fixed in 4.1.2; existing affected generated views also require the documented edit.10h CVE-2026-1112297.2 HIG

——0pfSense CE 2.7.0 through 2.9.0 contains a command injection vulnerability in services_captiveportal_hasync.php that allows users with only the Captive Portal HA privilege to execute commands as root. Attackers can set backwardsyncip to a malicious XMLRPC server returning connected_users with shell metacharacters in ip or mac fields, which captiveportal_load_pfctl passes unescaped to a pfctl shell command.18h CVE-2026-1112267.2 HIG

——0pfSense CE 2.4.5 through 2.9.0 contains an OS command injection vulnerability that allows authenticated WebGUI users with Advanced Admin Access privilege to execute commands as root via Login Protection settings. Attackers can submit sshguard threshold, block time, or detection time values containing newlines or $(...) that are written unvalidated to sshguard.conf and sourced as root on restart.18h CVE-2026-1112255.0 MED

——0Netgate pfSense CE 2.5.0 through 2.9.0 contains an OS command injection vulnerability in openvpn.learn-address.sh that allows authenticated VPN clients to execute commands as the unbound user. Attackers can embed shell metacharacters in the certificate common name or username, which is interpolated unquoted into su -c strings, when DNS Resolver client registration is enabled.18h CVE-2026-1112247.5 HIG

—

——0pfSense CE through 2.9.0 contains an OS command injection vulnerability in the OpenVPN openvpn.connect_async.sh script that allows authenticated VPN users to execute commands as root via crafted usernames. Attackers authenticated through RADIUS or LDAP can use usernames containing single quotes and shell metacharacters to break out of the eval'd pfctl anchor name on connect or disconnect.18h CVE-2026-1112187.2 HIG

——0Netgate pfSense CE 2.7.0 through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with Traffic Shaper Limiters privileges to execute root commands by tampering with the limiter number field. Attackers can submit a malicious hidden 'number' value when editing a limiter, then delete it so delete_queue() passes the unquoted value to dnctl via /bin/sh as root.18h
