Description
Lantronix SLC8000 before firmware v9.7.0.3, 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.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`). Because exploitation targets the running service rather than your application code, O3 also flags the exploit behaviour from runtime telemetry and egress traffic.
Remediation status
No fixed release is recorded for CVE-2026-80149 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Reduce reachability while you patch: restrict network access to the service to trusted sources, disable or gate the affected component where your deployment allows it, and add a WAF/IPS signature if one exists for CVE-2026-80149. O3's runtime protection blocks the server-side request forgery (ssrf) flaw at execution, which holds the line on hosts you cannot patch immediately.
How O3 protects you
O3 detects and blocks CVE-2026-80149 exploitation at runtime with eBPF exploit-chain detection, plus L7 egress monitoring that catches a post-exploitation callback and cuts the attacker's outbound channel.
Tailored to CVE-2026-80149. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
