CVE-2025-15398 identifies a security vulnerability in the Uasoft badaso product, specifically versions 2.9.0 through 2.9.7. The vulnerability is located in the forgetPassword function of the BadasoAuthController.php file, part of the Token Handler component. This function is responsible for handling password recovery requests. Due to improper implementation, the password recovery process is weak and can be manipulated remotely by attackers to bypass intended security controls. The attack vector is network-based (AV:N), requiring no privileges (PR:N), no user interaction (UI:N), and no authentication, but the attack complexity is high (AC:H), indicating that exploitation requires significant effort or specific conditions. The vulnerability impacts the confidentiality of user accounts by enabling unauthorized password resets, but it does not affect integrity or availability directly. The CVSS 4.0 score of 6.3 reflects a medium severity level, with partial impact on confidentiality and no impact on integrity or availability. The vendor was notified but has not responded or issued a patch, and no known exploits have been reported in the wild yet. The public disclosure of the vulnerability increases the risk of exploitation over time. The lack of vendor response and patch availability necessitates proactive mitigation by users of the affected software. The vulnerability is particularly relevant for organizations relying on badaso for authentication and user management in their web applications.

For European organizations using Uasoft badaso versions up to 2.9.7, this vulnerability poses a risk of unauthorized account access through weak password recovery processes. Attackers exploiting this flaw could reset passwords without proper authorization, potentially leading to account takeover, data exposure, and further lateral movement within affected systems. This could compromise sensitive personal data, intellectual property, or critical business functions depending on the application context. The medium severity and high attack complexity somewhat limit immediate widespread exploitation, but the public disclosure and lack of vendor patch increase long-term risk. Organizations in sectors with strict data protection requirements, such as finance, healthcare, and government, may face regulatory and reputational consequences if exploited. Additionally, the vulnerability could be leveraged as an initial access vector in multi-stage attacks targeting European enterprises. The impact is amplified in environments where badaso is integrated with other critical systems or where password recovery is a primary means of account access restoration.

Given the absence of an official patch, European organizations should implement several specific mitigations: 1) Restrict access to the forgetPassword endpoint by IP whitelisting or network segmentation to limit exposure. 2) Introduce multi-factor authentication (MFA) on password recovery workflows to add an additional verification layer. 3) Implement rate limiting and anomaly detection on password reset requests to identify and block suspicious activity. 4) Review and harden the password recovery logic by customizing or overriding the vulnerable function if possible. 5) Monitor logs for unusual password reset attempts and investigate promptly. 6) Educate users about phishing risks related to password resets. 7) Consider temporary disabling of the password recovery feature if feasible until a patch is available. 8) Engage with Uasoft or community forums for updates or unofficial patches. 9) Conduct penetration testing focused on authentication mechanisms to identify related weaknesses. These targeted actions go beyond generic advice and address the specific nature of the vulnerability and its exploitation complexity.
