1. EXECUTIVE SUMMARY

  • CVSS v4 9.3
  • ATTENTION: Exploitable remotely/low attack complexity
  • Vendor: Tigo Energy
  • Equipment: Cloud Connect Advanced
  • Vulnerabilities: Use of Hard-coded Credentials, Command Injection, Predictable Seed in Pseudo-Random Number Generator (PRNG).

2. RISK EVALUATION

Successful exploitation of these vulnerabilities could allow attackers to gain unauthorized administrative access using hard-coded credentials, escalate privileges to take full control of the device, modify system settings, disrupt solar energy production, interfere with safety mechanisms, execute arbitrary commands via command injection, cause service disruptions, expose sensitive data, and recreate valid session IDs to access sensitive device functions on connected solar inverter systems due to insecure session ID generation.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following versions of Cloud Connect Advanced are affected:

  • Cloud Connect Advanced: Versions 4.0.1 and prior

3.2 VULNERABILITY OVERVIEW

3.2.1 Use of Hard-coded Credentials CWE-798

Tigo Energy’s Cloud Connect Advanced (CCA) device contains hard-coded credentials that allow unauthorized users to gain administrative access. This vulnerability enables attackers to escalate privileges and take full control of the device, potentially modifying system settings, disrupting solar energy production, and interfering with safety mechanisms.

CVE-2025-7768 has been assigned to this vulnerability. A CVSS v3.1 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2025-7768. A base score of 9.3 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

3.2.2 Improper Neutralization of Special Elements used in a Command (‘Command Injection’) CWE-77

Tigo Energy’s CCA is vulnerable to a command injection vulnerability in the /cgi-bin/mobile_api endpoint when the DEVICE_PING command is called, allowing remote code execution due to improper handling of user input. When used with default credentials, this enables attackers to execute arbitrary commands on the device that could cause potential unauthorized access, service disruption, and data exposure.

CVE-2025-7769 has been assigned to this vulnerability. A CVSS v3.1 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2025-7769. A base score of 8.7 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

3.2.3 Predictable Seed in Pseudo-Random Number Generator (PRNG) CWE-337

Tigo Energy’s CCA device is vulnerable to insecure session ID generation in their remote API. The session IDs are generated using a predictable method based on the current timestamp, allowing attackers to recreate valid session IDs. When combined with the ability to circumvent session ID requirements for certain commands, this enables unauthorized access to sensitive device functions on connected solar optimization systems.

CVE-2025-7770 has been assigned to this vulnerability. A CVSS v3.1 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2025-7770. A base score of 8.7 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, 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.

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.

1. EXECUTIVE SUMMARY

  • CVSS v4 4.1
  • ATTENTION: Low attack complexity
  • Vendor: Mitsubishi Electric Iconics Digital Solutions, Mitsubishi Electric
  • Equipment: ICONICS Product Suite and Mitsubishi Electric MC Works64

3.2 VULNERABILITY OVERVIEW

3.2.1 Windows Shortcut Following (.LNK) CWE-64

An information tampering vulnerability due to Windows Shortcut Following exists in multiple processes in GENESIS64, MC Works64, and GENESIS. An attacker must first obtain the ability to execute low-privileged code on the target system to exploit this vulnerability. By creating a symbolic link, an attacker can cause the processes to make unauthorized writes to arbitrary files on the file system in any location that is accessible to the user under which the elevated processes are running, resulting in a denial-of-service (DoS) condition on the PC if the modified file is necessary for the operation of the PC.

CVE-2025-7376 has been assigned to this vulnerability. A CVSS v3.1 base score of 5.9 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:L/UI:R/S:C/C:N/I:H/A:N).

A CVSS v4 score has also been calculated for CVE-2025-7376. A base score of 4.1 has been calculated; the CVSS vector string is (AV:L/AC:L/AT:P/PR:L/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N).
