CVE-2025-15118 is an improper authorization vulnerability found in macrozheng mall versions 1.0.0 through 1.0.3, specifically within the /member/address/update/ endpoint of the Member component. The vulnerability arises due to insufficient authorization checks when processing requests to update member address information. This flaw allows an attacker with limited privileges—likely a logged-in user—to remotely manipulate address data of other members without proper authorization. The vulnerability does not require user interaction and can be exploited over the network without elevated privileges beyond limited access. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and limited impact on integrity (VI:L) with no impact on confidentiality or availability. Although no known exploits are currently active in the wild, the public disclosure of exploit details increases the risk of exploitation. The vulnerability could lead to unauthorized modification of user address data, potentially facilitating fraud, identity theft, or further attacks leveraging manipulated user information. The lack of patches or official mitigation links suggests that affected organizations need to implement compensating controls or monitor for suspicious activity until updates are available.

For European organizations using macrozheng mall e-commerce platforms, this vulnerability poses a moderate risk. Unauthorized modification of member address data can lead to fraudulent transactions, shipment interception, or identity-related fraud, impacting customer trust and regulatory compliance, especially under GDPR. Retailers and service providers relying on accurate member data may face operational disruptions and reputational damage. The vulnerability's remote exploitability without user interaction increases the attack surface, particularly for organizations with large user bases. While the impact on confidentiality and availability is limited, the integrity compromise can cascade into financial losses and legal liabilities. Organizations in Europe with significant e-commerce operations or those handling sensitive customer data should consider this vulnerability a priority for risk management.

1. Immediately audit and restrict access controls on the /member/address/update/ endpoint to ensure only authorized users can modify their own address data. 2. Implement strict server-side authorization checks validating that the requesting user is permitted to update the specified member address. 3. Monitor logs for unusual or unauthorized address update attempts, focusing on cross-account modifications. 4. If patches become available from macrozheng, prioritize timely deployment across all affected systems. 5. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the vulnerable endpoint. 6. Educate development teams on secure coding practices to prevent improper authorization flaws in future releases. 7. Consider multi-factor authentication and anomaly detection to reduce the risk of compromised accounts exploiting this vulnerability. 8. Engage in threat hunting to identify any signs of exploitation attempts within the network.
