CVE-2025-10422: Newbee-mall Authorization Bypass Vulnerability

CVE-2025-10422 Overview

CVE-2025-10422 is an improper authorization vulnerability [CWE-266] in the newbee-mall e-commerce application. The flaw resides in the paySuccess function of the /paySuccess endpoint within the Order Status Handler component. Attackers manipulate the orderNo argument to alter order status without proper authorization checks. The vendor follows a rolling release model, so no fixed version identifier is published. The vulnerable commit is tracked up to 613a662adf1da7623ec34459bc83e3c1b12d8ce7. Exploitation requires network access and low-privilege authentication, and public disclosure of the technique has already occurred.

Critical Impact

Authenticated remote attackers can manipulate the orderNo parameter at the /paySuccess endpoint to modify order payment status belonging to other users, undermining order integrity in affected newbee-mall deployments.

Technical Details for CVE-2025-10422

Vulnerability Analysis

The paySuccess function processes order payment confirmation requests through the /paySuccess endpoint. The handler accepts an orderNo parameter from the client and updates the associated order record. However, the implementation does not verify that the authenticated user owns the order referenced by orderNo.

This missing authorization check allows any authenticated user to submit arbitrary order numbers belonging to other accounts. The server then processes the state transition as if the request were legitimate. The weakness falls under [CWE-266: Incorrect Privilege Assignment], where the application grants broader privileges than intended for the request context.

Root Cause

The root cause is the absence of an ownership check inside the paySuccess handler. The function trusts the client-supplied orderNo without correlating it against the session identity. Business logic treats the parameter as a trusted reference rather than untrusted input requiring validation.

Attack Vector

Exploitation requires network reachability to the application and a valid low-privilege account. An attacker enumerates or guesses sequential order numbers, then issues HTTP requests to /paySuccess containing a target orderNo. The server processes the state change without rejecting the mismatched owner. Public exploit disclosure increases the likelihood of opportunistic abuse against exposed instances.

See the GitHub Issue #100 for the public technical description.

Detection Methods for CVE-2025-10422

Indicators of Compromise

• Multiple POST requests to /paySuccess from a single session referencing different orderNo values in short succession.
• Order state transitions in application logs where the authenticated user ID does not match the order owner ID.
• Sequential or incremented orderNo values in access logs indicating enumeration behavior.

Detection Strategies

• Deploy application-layer logging that captures the authenticated principal alongside the orderNo parameter for every /paySuccess invocation.
• Correlate order ownership records with the session identity at request time and alert on mismatches.
• Baseline normal order-completion rates per account and flag deviations consistent with scripted abuse.

Monitoring Recommendations

• Forward web server and application logs to a centralized analytics platform for cross-user correlation.
• Enable alerting on repeated 4xx-free /paySuccess calls from a single IP or session against varied order identifiers.
• Monitor database audit trails for order_status updates occurring outside the standard payment gateway callback flow.

How to Mitigate CVE-2025-10422

Immediate Actions Required

• Restrict public exposure of the newbee-mall /paySuccess endpoint behind authenticated reverse proxy controls until a code fix is applied.
• Apply a server-side ownership check that validates the current session user is the owner of the submitted orderNo before mutating state.
• Review historical logs for suspicious /paySuccess activity and reconcile any orders flagged as paid without matching payment gateway confirmation.

Patch Information

newbee-mall follows a rolling release model, so no versioned patch identifier has been published. Track remediation progress through the upstream GitHub Issue #100 and the follow-up issue comment thread. Additional vulnerability context is available in the VulDB entry #323856.

Workarounds

• Add an authorization guard that joins the orderNo lookup against the authenticated user ID and rejects mismatches with HTTP 403.
• Validate order state transitions by requiring a signed payment gateway callback token rather than trusting client-supplied order numbers.
• Rate-limit the /paySuccess endpoint per session to constrain enumeration attempts.

# Example nginx rate limit for the vulnerable endpoint
limit_req_zone $binary_remote_addr zone=paysuccess:10m rate=5r/m;

location = /paySuccess {
    limit_req zone=paysuccess burst=5 nodelay;
    proxy_pass http://newbee_mall_backend;
