1. EXECUTIVE SUMMARY CVSS v4 9.4 ATTENTION: Exploitable from an adjacent network/low attack complexity Vendor: SunPower Equipment: PVS6 Vulnerability: Use of Hard-Coded Credentials
2. RISK EVALUATION Successful exploitation of this vulnerability could allow attackers to gain full access to the device, enabling them to replace firmware, modify settings, disable the device, create SSH tunnels, and manipulate attached devices.
3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of SunPower PVS6 are affected: PVS6: Versions 2025.06 build 61839 and prior 3.2 VULNERABILITY OVERVIEW 3.2.1 USE OF HARD-CODED CREDENTIALS CWE-798 The SunPower PVS6’s BluetoothLE interface is vulnerable due to its use of hardcoded encryption parameters and publicly accessible protocol details. An attacker within Bluetooth range could exploit this vulnerability to gain full access to the device’s servicing interface. This access allows the attacker to perform actions such as firmware replacement, disabling power production, modifying grid settings, creating SSH tunnels, altering firewall settings, and manipulating connected devices. CVE-2025-9696 has been assigned to this vulnerability. A CVSS v3.1 base score of 9.6 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). A CVSS v4 score has also been calculated for CVE-2025-9696. A base score of 9.4 has been calculated; the CVSS vector string is (AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H). 3.3 BACKGROUND CRITICAL INFRASTRUCTURE SECTORS: Energy COUNTRIES/AREAS DEPLOYED: Worldwide COMPANY HEADQUARTERS LOCATION: United States 3.4 RESEARCHER Dagan Henderson reported this vulnerability to CISA.
4. MITIGATIONS SunPower did not respond to CISA’s attempt to coordinate these vulnerabilities. Users should contact SunPower for more information. CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as: Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks. No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time. This vulnerability is not exploitable remotely.
