CVE-2025-41031 Overview
CVE-2025-41031 is a missing authorization vulnerability [CWE-863] affecting Deporsite by T-INNOVA, a sports facility management platform. The flaw allows an unauthenticated attacker to modify other users' profile pictures by sending a crafted POST request to the /ajax/TInnova_c/FotoUsuario/llamadaAjax/uploadImage endpoint. The request abuses the IdPersona and Foto parameters to bypass access controls that should restrict image modifications to the account owner. INCIBE CERT published the coordinated advisory covering multiple vulnerabilities in the product.
Critical Impact
Unauthenticated attackers can overwrite any user's profile picture over the network without user interaction, enabling account defacement and potential reputational or social-engineering abuse.

Technical Details for CVE-2025-41031
Vulnerability Analysis
The vulnerability resides in the uploadImage handler exposed at /ajax/TInnova_c/FotoUsuario/llamadaAjax/uploadImage. The endpoint accepts a user identifier (IdPersona) and an image payload (Foto) but does not verify that the caller is authenticated or authorized to modify the specified user record. As a result, any remote actor can substitute any valid IdPersona value and replace the target user's profile picture. The issue maps to CWE-863 (Incorrect Authorization) because access control logic exists elsewhere in the application but is not enforced on this specific AJAX route.
While the confidentiality and integrity impact is limited to profile imagery, attackers can weaponize this for defacement campaigns, targeted harassment, or trust-building steps in social engineering against staff and members of sports facilities.
Root Cause
The root cause is a missing authorization check on a state-changing AJAX endpoint. The server trusts the client-supplied IdPersona parameter to identify the target account instead of deriving the identifier from an authenticated session context.
Attack Vector
The attack is delivered over the network with low complexity and requires no privileges or user interaction. An attacker crafts a single POST request containing an arbitrary IdPersona value and an image file in the Foto parameter, then submits it directly to the vulnerable AJAX route. Successful requests silently replace the target user's profile image.
No verified proof-of-concept code is published. See the INCIBE CERT Vulnerability Notice for the coordinated disclosure details.
Detection Methods for CVE-2025-41031
Indicators of Compromise
- Unauthenticated POST requests to /ajax/TInnova_c/FotoUsuario/llamadaAjax/uploadImage in web server access logs.
- Multiple uploadImage requests iterating across sequential IdPersona values from the same source IP.
- Unexpected profile picture changes reported by users who did not initiate an upload.
Detection Strategies
- Correlate web access logs for the FotoUsuario/llamadaAjax/uploadImage path against authenticated session identifiers, and flag any requests lacking a valid session cookie or bearer token.
- Alert when a single client submits uploadImage requests referencing more than one distinct IdPersona value within a short window.
- Compare uploaded file hashes against known-benign baselines to identify bulk overwrite activity.
Monitoring Recommendations
- Enable verbose logging on the Deporsite web application server, including request bodies for the /ajax/TInnova_c/FotoUsuario/ routes.
- Forward web server and WAF telemetry to a central analytics platform for retroactive hunting and correlation with user complaints.
- Track profile image change events in the application audit log and reconcile them with authenticated user activity.
How to Mitigate CVE-2025-41031
Immediate Actions Required
- Contact T-INNOVA to obtain a fixed release or hotfix for Deporsite and apply it as soon as available.
- Restrict access to the /ajax/TInnova_c/FotoUsuario/llamadaAjax/uploadImage endpoint at the web server or reverse proxy tier until a patch is deployed.
- Audit stored profile images for unauthorized changes since the application was first exposed.
Patch Information
No vendor patch URL or fixed version is listed in the NVD entry at the time of writing. Refer to the INCIBE CERT Vulnerability Notice for coordination status and contact T-INNOVA directly for remediation guidance.
Workarounds
- Enforce authentication at the reverse proxy or web application firewall for all /ajax/TInnova_c/FotoUsuario/ paths, rejecting requests without a valid session cookie.
- Add a WAF rule that blocks POST requests to uploadImage where the IdPersona value does not match the authenticated user's identifier.
- Rate-limit requests to the uploadImage endpoint to slow enumeration attempts against multiple accounts.
