CVE-2025-13114: Critical Authorization Flaw Threatens macrozheng mall-swarm Users

by

Overview

CVE-2025-13114 is a medium severity vulnerability affecting macrozheng’s mall-swarm, specifically versions up to 1.0.3. This vulnerability allows for improper authorization when updating attributes via the updateAttr function in the /cart/update/attr file. A remote attacker can exploit this flaw, potentially leading to unauthorized modification of cart attributes and possibly affecting order processing and pricing. The vendor was notified but did not respond. Publicly available exploit code exists, increasing the risk of exploitation.

Technical Details

The vulnerability resides in the updateAttr function within the /cart/update/attr endpoint. By manipulating input parameters, an attacker can bypass authorization checks. This likely involves insufficient validation of user roles or permissions when processing attribute updates. An attacker could potentially modify attributes associated with other users’ shopping carts or modify attributes in ways not intended by the application logic. The issue stems from the lack of proper access control when handling attribute updates.

CVSS Analysis

The Common Vulnerability Scoring System (CVSS) v3 score for CVE-2025-13114 is 6.3 (Medium). This score indicates a significant level of risk. The exploit is remotely accessible, and while the impact might not be complete system compromise, it could lead to data integrity issues and potential financial loss due to manipulated cart attributes.

Possible Impact

Successful exploitation of CVE-2025-13114 could have several negative consequences:

  • Unauthorized Cart Modification: Attackers can modify attributes of carts they should not have access to.
  • Price Manipulation: Modified attributes can lead to incorrect pricing, affecting revenue and customer trust.
  • Order Disruption: Changes to cart attributes could cause errors during order processing and fulfillment.
  • Reputational Damage: Exploitation leading to incorrect orders or manipulated pricing can damage the mall-swarm’s reputation.

Mitigation or Patch Steps

Unfortunately, as the vendor has not responded, there are no official patches available. Here are some potential mitigation strategies:

  • Input Validation: Implement robust input validation and sanitization on the updateAttr function to prevent malicious input.
  • Access Control: Strengthen access control mechanisms to ensure that only authorized users can modify specific cart attributes. Verify user identity and permissions before allowing attribute updates.
  • Rate Limiting: Implement rate limiting on the /cart/update/attr endpoint to reduce the impact of potential attacks.
  • Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) with rules to detect and block suspicious requests targeting the vulnerable endpoint.
  • Monitor and Alert: Implement monitoring and alerting for suspicious activity related to cart attribute updates.
