Description

Intellian Aptus Web 1.24 allows remote attackers to execute arbitrary OS commands via the Q field within JSON data to the cgi-bin/libagent.cgi URI. NOTE: a valid sid cookie for a login to the intellian default account might be needed.

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 18 September 2026. Confidence: high.

critical priorityCVSS 9.8 with public exploit code and very high EPSS makes remote compromise likely for any internet-exposed instance.

What it is

Impact

An attacker can run arbitrary operating system commands on the device, gaining full control of the appliance and any data or network access it holds.

Attack surface

Reachable over the network via HTTP requests to cgi-bin/libagent.cgi; the CVSS vector shows no privileges or user interaction required, though the description notes a valid sid cookie from the default Intellian account might be needed.

Exploitation

Not listed in CISA KEV, but EPSS is 0.825 (99.6th percentile) and multiple references are tagged Exploit, indicating public exploit code is available.

What to do

Patch or upgrade Intellian Aptus Web beyond 1.24 per vendor guidance; if no fix exists, isolate the device.
Change the default Intellian account credentials and enforce strong unique passwords.
Block or restrict external access to cgi-bin/libagent.cgi and the web interface using firewall rules or a reverse proxy.
Place the device on a segmented management network with no outbound internet access.

Detection

Monitor HTTP requests to cgi-bin/libagent.cgi for JSON payloads with suspicious Q field values containing shell metacharacters.
Alert on unexpected child processes or shell execution spawned by the web server process.
Review authentication logs for logins using the default Intellian account or anomalous sid cookie use.
