AI risk analysis
- Summary
- This vulnerability allows unauthenticated attackers to establish SSH connections to arbitrary endpoints, potentially exposing internal network resources to external access.
- Exploitability
- Exploitation is relatively straightforward as it requires modifying the rooturl parameter, which can be done through web connections. Precondition is that the WebSSH/WebTelnet listener is enabled.
- Blast radius
- If exploited, attackers can gain access to internal network resources, leading to potential data exfiltration or control of internal systems.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to firmware v9.7.0.3 or later for SLC8000, v9.7.0.2 or later for SLC9000, v9.7.0.1 or later for EMG8500/EMG7500, or disable the WebSSH/WebTelnet listener feature.

NVD description
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 contain a server-side request forgery vulnerability in the WebSSH/WebTelnet listener that allows unauthenticated attackers to cause the affected device to establish SSH connections to attacker-controlled endpoints. 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 SSH 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.
