CVE-2024-0186 is a vulnerability identified in HuiRan Host Reseller System version 2.0.0 and earlier. The issue resides in the password recovery functionality accessed via the HTTP POST request handler at the endpoint /user/index/findpass?do=4. Specifically, the vulnerability is categorized under CWE-640, which refers to weak password recovery mechanisms. This weakness allows an attacker to potentially exploit the password recovery process to gain unauthorized access or manipulate account credentials. The vulnerability can be exploited remotely without requiring authentication or user interaction, but the attack complexity is considered high, and the exploitability is difficult. The CVSS v3.1 base score is 3.7, indicating a low severity primarily due to the high attack complexity and lack of direct confidentiality or availability impact. No known exploits are currently observed in the wild, and no patches have been published yet. The vulnerability disclosure date is January 2, 2024. The weakness in the password recovery process could allow an attacker to bypass intended security controls, potentially leading to limited integrity impact, such as unauthorized password resets or account takeovers, but without direct data confidentiality or system availability compromise.

For European organizations using HuiRan Host Reseller System, this vulnerability poses a risk primarily to the integrity of user accounts managed through the system. Since the system is used for hosting reselling, unauthorized access could lead to manipulation of hosting accounts, potentially resulting in service disruptions or unauthorized changes to hosted content. Although the severity is low, the impact could be more significant if attackers leverage this weakness as a foothold for further attacks within the organization’s infrastructure. The remote exploitability without authentication increases the risk surface, especially for organizations with externally accessible password recovery endpoints. However, the high attack complexity and lack of known active exploitation reduce immediate risk. Organizations relying on this system should be aware that attackers might attempt to exploit this vulnerability to reset passwords or gain unauthorized access, which could indirectly affect service integrity and customer trust.

Given the absence of an official patch, European organizations should implement compensating controls to mitigate this vulnerability. These include: 1) Restricting access to the password recovery endpoint through network controls such as IP whitelisting or VPN access to reduce exposure. 2) Enhancing monitoring and logging of password recovery attempts to detect anomalous or repeated requests indicative of exploitation attempts. 3) Implementing multi-factor authentication (MFA) on accounts to reduce the impact of unauthorized password resets. 4) Reviewing and strengthening the password recovery process by adding additional verification steps, such as out-of-band confirmation or security questions, if possible. 5) Educating users about phishing and social engineering risks related to password recovery. 6) Planning for an upgrade or patch deployment once the vendor releases a fix. 7) Conducting regular security assessments of the hosting reseller system to identify and remediate other potential weaknesses.
