CVE-2025-8742 is a vulnerability identified in version 1.0.3 of the macrozheng mall software, specifically affecting the Admin Login component. The core issue is an improper restriction of excessive authentication attempts, which means the system does not adequately limit the number of login attempts an attacker can make. This flaw can potentially allow an attacker to perform brute-force or credential-stuffing attacks remotely to gain unauthorized access. However, the attack complexity is rated as high, indicating that exploitation requires significant effort or specific conditions. The vulnerability does not require any privileges or user interaction to exploit, but the impact on confidentiality is low, with no direct impact on integrity or availability. The CVSS 4.0 base score is 6.3 (medium severity), reflecting these factors. The vendor has not responded to disclosure attempts, and no patches or known exploits in the wild have been reported yet. This vulnerability highlights a weakness in authentication controls that could be leveraged to compromise administrative access if combined with other weaknesses or valid credentials.

For European organizations using macrozheng mall 1.0.3, this vulnerability poses a moderate risk. If exploited, attackers could gain unauthorized administrative access, potentially leading to data exposure, unauthorized changes, or further compromise of the e-commerce platform. Given the administrative access level, the confidentiality of customer data and business information could be at risk. However, the high complexity of exploitation and lack of known active exploits reduce immediate risk. Still, organizations relying on this software should be vigilant, as attackers might develop more effective exploitation techniques over time. The impact is particularly relevant for companies handling sensitive customer data or financial transactions, as unauthorized admin access could facilitate fraud or data breaches.

Since no patch is currently available and the vendor is unresponsive, European organizations should implement compensating controls. These include: 1) Deploying Web Application Firewalls (WAFs) to detect and block excessive login attempts and suspicious IP addresses. 2) Implementing network-level rate limiting and IP blacklisting to reduce brute-force attack surface. 3) Enforcing multi-factor authentication (MFA) for all administrative accounts to mitigate the risk of credential compromise. 4) Monitoring login attempts and alerting on abnormal authentication patterns. 5) Restricting admin login access to trusted IP ranges or VPNs where possible. 6) Regularly reviewing and updating credentials and removing unused admin accounts. These measures can significantly reduce the risk of exploitation until an official patch or update is released.
