CVE-2025-41069 is an authorization bypass vulnerability classified under CWE-639 (Authorization Bypass Through User-Controlled Key) affecting T-Innova's DeporSite DSuite 2025, specifically version v02.14.1115. The vulnerability arises from an Insecure Direct Object Reference (IDOR) flaw in the endpoint '/ajax/TInnova_v2/Formulario_Consentimiento/llamadaAjax/obtenerDatosConsentimientos', where the 'idUsuario' parameter is user-controlled and insufficiently validated. This allows an attacker to craft requests with arbitrary 'idUsuario' values to retrieve or modify consent data belonging to other users without proper authorization. The vulnerability does not require user interaction or authentication, making it remotely exploitable over the network with low complexity. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L, meaning limited privileges but no full authentication), no user interaction (UI:N), and limited impact on confidentiality (VC:N), integrity (VI:L), and no impact on availability (VA:N). Although no known exploits are currently reported in the wild, the flaw poses a risk of unauthorized data exposure or modification, potentially violating data protection regulations. The lack of published patches necessitates immediate mitigation through configuration or compensating controls. The vulnerability was assigned and published by INCIBE, reflecting its recognition by a European cybersecurity authority.

For European organizations, the impact of CVE-2025-41069 can be significant, particularly for those handling sensitive personal data such as user consents related to health, sports, or other regulated sectors. Unauthorized access or modification of consent data can lead to breaches of confidentiality and integrity, undermining user trust and potentially violating GDPR and other data protection laws. This could result in regulatory fines, reputational damage, and legal liabilities. Since the vulnerability allows attackers to bypass authorization controls without authentication, it increases the risk of insider threats or external attackers exploiting the system remotely. Organizations relying on T-Innova DeporSite DSuite 2025 for managing user consents or related data must consider the risk of data leakage or unauthorized data manipulation, which could affect operational integrity and compliance posture. The medium severity rating suggests moderate but non-negligible risk, warranting prompt remediation to avoid escalation or exploitation in targeted attacks.

To mitigate CVE-2025-41069 effectively, European organizations should implement the following specific measures: 1) Immediately audit all endpoints handling user-controlled parameters, especially 'idUsuario', to ensure strict server-side authorization checks are in place verifying that the requesting user is permitted to access or modify the specified resource. 2) Employ parameter validation and access control mechanisms that bind user identity to resource access, preventing horizontal privilege escalation. 3) Monitor and log access to sensitive endpoints to detect anomalous or unauthorized requests targeting user identifiers. 4) If patching is not yet available, consider deploying Web Application Firewalls (WAFs) with custom rules to block suspicious requests manipulating 'idUsuario' parameters. 5) Conduct internal penetration testing focusing on IDOR vulnerabilities to identify similar weaknesses. 6) Educate developers and administrators on secure coding practices related to authorization and input validation. 7) Prepare incident response plans to address potential data exposure incidents stemming from this vulnerability. 8) Engage with T-Innova for updates on patches or official remediation guidance and apply them promptly once released.
