CVE-2025-8741 is a medium-severity vulnerability affecting macrozheng mall versions 1.0.0 through 1.0.3. The vulnerability arises from the cleartext transmission of sensitive information during interactions with the /admin/login endpoint. This means that when administrators or users log in, sensitive data such as credentials or session tokens may be transmitted without encryption, exposing them to interception by network attackers. The vulnerability can be exploited remotely without authentication or user interaction, but the attack complexity is rated as high, indicating that exploitation requires advanced skills or specific conditions. The CVSS 4.0 vector (AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P) confirms that the attack is network-based, requires no privileges or user interaction, but the high attack complexity and low impact on confidentiality reduce the overall severity to medium (6.3). The vendor has not responded to disclosure attempts, and no patches or mitigations have been published yet. Although no known exploits are currently in the wild, public disclosure of the exploit code increases the risk of future attacks. The vulnerability primarily impacts the confidentiality of sensitive data during login, with no direct impact on integrity or availability. The lack of encryption on sensitive login data could allow attackers to perform man-in-the-middle attacks, capturing credentials and potentially gaining unauthorized access to administrative functions if successful.

For European organizations using macrozheng mall versions up to 1.0.3, this vulnerability poses a risk of credential interception during administrative login processes. This could lead to unauthorized access to e-commerce backend systems, potentially resulting in data breaches, manipulation of product or order data, and exposure of customer information. Given the nature of e-commerce platforms, such breaches could damage customer trust, violate GDPR regulations due to exposure of personal data, and result in financial losses or regulatory penalties. The medium severity and high attack complexity somewhat limit immediate widespread exploitation, but the public availability of exploit details means determined attackers could eventually succeed, especially in environments with weak network security or unsegmented administrative access. Organizations relying on macrozheng mall for critical business operations should consider the risk of operational disruption and reputational damage if administrative credentials are compromised.

Since no official patches are available, European organizations should implement compensating controls immediately. These include enforcing the use of secure transport protocols such as TLS 1.2 or higher to encrypt all traffic to and from the /admin/login endpoint, ideally by deploying a reverse proxy or web application firewall (WAF) that enforces HTTPS and blocks unencrypted HTTP requests. Network segmentation should be applied to restrict access to the administrative interface only to trusted IP addresses or VPN users. Multi-factor authentication (MFA) should be enabled for all administrative accounts to reduce the risk of credential misuse if interception occurs. Regular monitoring of network traffic for suspicious activity around the login endpoint is recommended. Organizations should also consider migrating to updated or alternative e-commerce platforms that have addressed this vulnerability. Finally, maintaining an incident response plan that includes credential compromise scenarios will help mitigate potential damage.
