CVE-2025-8742 is a vulnerability identified in macrozheng mall version 1.0.3, 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, attempting to guess administrative credentials without being blocked or slowed down by rate limiting or account lockout mechanisms. However, the attack complexity is rated as high, indicating that exploitation requires significant effort, skill, or specific conditions. The vulnerability does not require any privileges or user interaction and can be exploited remotely over the network. The CVSS 4.0 base score is 6.3, categorized as medium severity, reflecting a moderate impact primarily on confidentiality due to potential unauthorized access to administrative functions. The vendor has not responded to disclosure attempts, and no patches or known exploits in the wild have been reported yet. The vulnerability's exploitation could lead to unauthorized administrative access if successful, potentially compromising the entire e-commerce platform managed by macrozheng mall. Since the vulnerability affects an admin login, the integrity and availability of the system could also be indirectly impacted if attackers gain control or disrupt services.

For European organizations using macrozheng mall 1.0.3, this vulnerability poses a risk of unauthorized administrative access through brute-force attacks, which could lead to data breaches, manipulation of e-commerce transactions, or disruption of services. Given the administrative level access targeted, attackers could alter product listings, customer data, or financial information, impacting business operations and customer trust. The medium severity and high attack complexity suggest that while exploitation is not trivial, motivated attackers with sufficient resources could succeed, especially if combined with other vulnerabilities or weak credential policies. The lack of vendor response and patches increases the risk exposure duration. European organizations in retail sectors relying on macrozheng mall could face regulatory compliance issues under GDPR if customer data is compromised. Additionally, disruption or manipulation of e-commerce platforms could have financial and reputational consequences.

Specific mitigation steps include implementing external rate limiting and account lockout policies at the network or application firewall level to compensate for the lack of built-in restrictions. Organizations should enforce strong password policies and consider multi-factor authentication (MFA) for administrative accounts to reduce the risk of credential compromise. Monitoring and alerting on repeated failed login attempts can help detect brute-force activities early. If possible, restrict administrative login access by IP whitelisting or VPN-only access to reduce the attack surface. Regularly audit and update credentials, and consider deploying Web Application Firewalls (WAFs) with rules to detect and block brute-force patterns. Since no patch is available, organizations should also evaluate the feasibility of upgrading to newer, more secure versions or alternative platforms. Finally, maintain comprehensive logging and incident response plans to quickly address any suspected compromise.
