A low-privileged remote attacker can exploit a command injection vulnerability in the /index.php/ajax/get_iodd_port_info endpoint using user or operator credentials allowing execution of commands with root privileges on the device.
AnalysisAI
Command injection in Pepperl+Fuchs ICE2/ICE3 IO-Link Master devices and OEM equivalents allows a low-privileged authenticated attacker to execute arbitrary OS commands as root via the /index.php/ajax/get_iodd_port_info PHP endpoint. Affected hardware spans multiple ICE2 and ICE3 form factors (G65L, K45P, K45S housings) as well as Phoenix Contact IOL MA8 and additional OEM-branded variants sharing the same firmware. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires (1) network access to the HTTP/HTTPS management interface of the affected IO-Link Master device, and (2) valid user or operator credentials - the CVSS PR:L metric confirms that low-privileged accounts (not just administrator) are sufficient to reach the vulnerable endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 vector (AV:N/AC:L/PR:L/UI:N) accurately characterizes the core risk: the vulnerability is network-reachable, requires no special configuration to trigger, and demands only low-privileged credentials that are likely widely held in operational environments where multiple operators share device access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult CERTVDE advisories VDE-2026-014 (https://www.certvde.com/en/advisories/VDE-2026-014/), VDE-2026-027 (https://www.certvde.com/en/advisories/VDE-2026-027/), and VDE-2026-028 (https://www.certvde.com/en/advisories/VDE-2026-028/) for vendor-released firmware updates and exact patched versions; no specific fixed firmware version number was independently confirmed in available data at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Pepperl+Fuchs ICE2/ICE3 and Phoenix Contact IOL MA8 devices deployed in your network, determine current firmware versions, and assess network accessibility to the management interface (/index.php/ajax/get_iodd_port_info). …
