CVE-2025-36758 is a medium-severity vulnerability identified in the SolaX Power SolaX Cloud platform, specifically affecting versions released before June 27, 2025. The vulnerability is classified under CWE-307, which pertains to improper restriction of excessive authentication attempts. The core issue arises from the ability to bypass the intended limit on authentication attempts by exploiting the 'Forgot Password' functionality as an oracle. This means that an attacker can use this feature to repeatedly test or guess credentials or tokens without triggering the usual lockout or throttling mechanisms designed to prevent brute-force attacks. The CVSS 4.0 base score of 6.3 reflects a network attack vector with low attack complexity, no privileges required, and no user interaction needed. The vulnerability impacts confidentiality and integrity to a limited extent, as it allows an attacker to potentially enumerate valid accounts or reset passwords by circumventing rate-limiting controls. However, there is no indication that availability is affected. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability was reserved in April 2025 and published in September 2025, indicating recent discovery and disclosure. The SolaX Cloud platform is used for managing solar power systems, implying that exploitation could lead to unauthorized access to energy management systems or user accounts, potentially impacting operational control or data privacy.

For European organizations, particularly those involved in renewable energy management or utilizing SolaX Power's solar energy solutions, this vulnerability poses a risk of unauthorized account access. Exploitation could allow attackers to bypass authentication attempt limits, facilitating brute-force or credential-stuffing attacks via the 'Forgot Password' feature. This could lead to unauthorized control or monitoring of solar power installations, potentially disrupting energy management or exposing sensitive operational data. While the direct impact on physical infrastructure is limited by the scope of the cloud platform's controls, compromised accounts could be leveraged for further attacks or data exfiltration. Given Europe's strong emphasis on renewable energy and smart grid technologies, such vulnerabilities could undermine trust in energy providers and complicate compliance with data protection regulations like GDPR if personal or operational data is exposed. The medium severity suggests a moderate risk that requires timely mitigation to prevent escalation or chaining with other vulnerabilities.

European organizations using SolaX Cloud should implement the following specific mitigations: 1) Immediately verify if their SolaX Cloud instances are running affected versions and prioritize upgrading to patched versions once available. 2) Until patches are released, restrict access to the 'Forgot Password' functionality through additional controls such as CAPTCHA, IP rate limiting, or multi-factor authentication (MFA) on password reset requests to reduce abuse potential. 3) Monitor authentication logs for unusual patterns indicative of brute-force or enumeration attempts via the password reset feature. 4) Educate users on recognizing phishing attempts that could exploit this vulnerability. 5) Implement compensating controls such as account lockouts or alerts triggered by suspicious password reset activity. 6) Coordinate with SolaX Power for timely updates and advisories. 7) Consider network-level protections like Web Application Firewalls (WAFs) configured to detect and block excessive password reset requests. These measures go beyond generic advice by focusing on the specific bypass vector and the operational context of the vulnerability.
