CVE-2026-9717: OS Command Injection in Schneider Electric PowerLogic P7

Technical summary

This is a CWE-78 OS command injection vulnerability in Schneider Electric PowerLogic P7 and its firmware. The affected service does not adequately neutralize special shell metacharacters in user-supplied input before passing it to a system command interpreter. An attacker with privileged authentication credentials can inject OS commands that execute with elevated privileges, circumventing normal security controls. The vulnerability is network-accessible, has low attack complexity, and requires high-privilege credentials but no additional user interaction to trigger.

Business impact

Exploitation could result in complete compromise of PowerLogic P7 devices. An attacker gaining command execution with elevated privileges can exfiltrate sensitive operational data (monitoring and control information), modify system configuration, disable monitoring and alerting, or cause denial of service. For organizations relying on PowerLogic P7 for energy management and power quality analysis, this poses significant operational risk and potential regulatory compliance impact if availability or data integrity is compromised.

Affected systems

Schneider Electric PowerLogic P7 and its associated firmware versions are affected. Organizations using PowerLogic P7 for power monitoring and analytics in industrial, commercial, or critical infrastructure environments should verify their specific firmware versions against Schneider Electric's advisory to determine exposure. The vulnerability requires network access to the device and valid privileged credentials.

Exploitability

While this vulnerability requires an authenticated user with high-privilege access (CVSS PR:H), the network attack vector and low attack complexity mean exploitation is straightforward once an attacker obtains or compromises privileged credentials. The lack of KEV designation suggests this has not yet been publicly exploited, but the attack surface—network exposure combined with common credential compromise scenarios—makes it a reasonable concern for organizations with internet-facing or untrusted-network-adjacent PowerLogic P7 devices.

Remediation

Schneider Electric has released patches to address this vulnerability. Organizations should apply the patched firmware versions to all affected PowerLogic P7 devices. Verify the specific firmware version on each device and cross-reference it against Schneider Electric's security advisory to confirm the appropriate patched version. Interim mitigations include restricting network access to PowerLogic P7 devices via firewall rules, limiting privilege levels for user accounts, and disabling remote access if operationally feasible.

Patch guidance

Contact Schneider Electric or consult their security advisory for the specific patched firmware versions applicable to your PowerLogic P7 devices. Firmware updates should be tested in a non-production environment first to ensure compatibility with existing monitoring and control workflows. Schedule patching during a maintenance window to minimize operational disruption. After patching, verify that all functionality has been restored and that no legacy accounts with unnecessary privilege levels remain active.

Detection guidance

Monitor PowerLogic P7 logs for unusual command execution, particularly commands with shell metacharacters (pipes, semicolons, backticks) originating from authenticated sessions. Review access logs to identify which accounts have accessed the device and when. Network-based detection could flag attempts to inject command metacharacters in requests to the PowerLogic P7 service. Maintain baseline inventory of legitimate administrative access patterns and alert on deviations.

Why prioritize this

Despite not being in the KEV catalog, this vulnerability warrants priority attention because it combines network accessibility, elevated-privilege command execution, and complete system compromise potential (high CVSS score of 7.2). While exploitation requires high-privilege credentials, compromised admin accounts are common attack outcomes. PowerLogic P7 devices are often part of critical operational infrastructure, making availability and integrity failures particularly impactful.

Risk score, explained

The CVSS 3.1 score of 7.2 (HIGH) reflects: (1) network attack vector—no physical proximity required; (2) low attack complexity—straightforward exploitation once authenticated; (3) high privilege requirement—partially mitigating factor; (4) high impact to confidentiality, integrity, and availability—complete system compromise possible. The lack of user interaction (UI:N) means no social engineering is needed. The score is high but not critical because authentication is required, yet organizations should treat it as urgent given the control and monitoring nature of affected devices.
