CVE-2025-10992: Roncoo Pay Authentication Bypass Flaw

CVE-2025-10992 Overview

CVE-2025-10992 is an improper authorization vulnerability [CWE-266] in the roncoo-pay open-source payment platform. The flaw resides in an unknown function of the /user/info/lookupList endpoint. Remote attackers can manipulate requests to this endpoint to bypass authorization controls and access user information data that should be restricted. The exploit has been publicly disclosed. The affected commit is identified as 9428382af21cd5568319eae7429b7e1d0332ff40, though roncoo-pay uses a rolling release model without discrete version identifiers. The vendor was contacted about this disclosure but did not respond.

Critical Impact
Remote unauthenticated attackers can exploit improper authorization in the /user/info/lookupList endpoint to access restricted user information without credentials or user interaction.

Technical Details for CVE-2025-10992

Vulnerability Analysis

The vulnerability affects an unknown function tied to the /user/info/lookupList endpoint in roncoo-pay. The endpoint fails to enforce proper authorization checks before returning user information. An attacker sends crafted HTTP requests over the network without authentication and receives data intended for privileged users.

The issue is categorized under [CWE-266] Incorrect Privilege Assignment. The vulnerability class typically arises when application logic assumes a caller holds a privilege level that was never validated against the requested resource. Because roncoo-pay handles payment-related user records, exposed data can include account attributes tied to financial workflows.

Exploitation requires only network access to the application. No user interaction, no elevated privileges, and no local access are needed.

Root Cause

The root cause is missing or insufficient authorization validation on the /user/info/lookupList handler. The endpoint likely returns list data intended for administrative or account-holder contexts but does not verify that the requesting principal is authorized to view the records. See the CNBlogs Analysis Post and VulDB CTI ID #325919 for additional technical context.

Attack Vector

The attack vector is network-based. An adversary issues HTTP requests directly against the /user/info/lookupList route on an exposed roncoo-pay instance. Because the flaw is in server-side authorization logic, standard client-side controls do not prevent exploitation. Public disclosure of the exploit lowers the barrier for opportunistic scanning and abuse.

No verified proof-of-concept code is included in this advisory. Refer to VulDB #325919 and VulDB Submission #653738 for the disclosed exploit details.

Detection Methods for CVE-2025-10992

Indicators of Compromise

Unauthenticated or low-privilege HTTP requests to /user/info/lookupList returning HTTP 200 with user record payloads
Sudden spikes in request volume to /user/info/ routes from single IPs or scanner user agents
Access log entries showing enumeration patterns against the lookup endpoint

Detection Strategies

Deploy web application firewall (WAF) rules that require authenticated session cookies or bearer tokens on all /user/info/* paths
Correlate application access logs with authentication logs to identify requests that returned data without a valid session
Alert on anomalous response sizes from /user/info/lookupList indicating bulk record enumeration

Monitoring Recommendations

Enable verbose access logging on the roncoo-pay application server and forward logs to a centralized SIEM
Establish a baseline for legitimate request rates to user information endpoints and alert on deviations
Monitor egress traffic from the payment application for unusual outbound data volumes indicating exfiltration

How to Mitigate CVE-2025-10992

Immediate Actions Required

Restrict network exposure of the roncoo-pay instance so /user/info/lookupList is not reachable from untrusted networks
Place the affected endpoint behind an authenticating reverse proxy or API gateway that enforces session validation
Audit application logs retroactively for prior unauthorized requests to the endpoint
Review user records that may have been enumerated and notify affected account holders where required

Patch Information

At the time of publication, the vendor had not responded to the disclosure and no official patch is referenced in the NVD advisory. Because roncoo-pay follows a rolling release model, monitor the upstream repository for commits that add authorization checks to the /user/info/lookupList handler. Track the VulDB CTI ID #325919 entry for updates on fix availability.

Workarounds

Add a reverse proxy rule (nginx, Apache, or API gateway) that requires a valid authenticated session before forwarding requests to /user/info/lookupList
Implement an application-layer filter or servlet interceptor that validates the caller's role against the requested resource before invoking the endpoint
Temporarily block external access to the endpoint via firewall rules if the functionality is not required for production traffic

bash

# Example nginx configuration to require authentication on the vulnerable endpoint
location /user/info/lookupList {
    auth_request /_auth_check;
    error_page 401 = @unauthorized;
    proxy_pass http://roncoo_pay_backend;
}

location @unauthorized {
    return 401 "Authentication required";
}
