Medical Management System Flaw Lets Attackers Reset Any Password

Executive Summary

A vulnerability tracked as CVE-2025-67437, carrying a CVSS base score of 6.5, has been disclosed in a Medical Management System identified by the Git commit hash a81df1ce700a9662cb136b27af47f4cbde64156b. The flaw stems from insecure permissions that allow an arbitrary user to reset any other user's password without proper authorization, according to a report filed on the Chinese code-hosting platform Gitee. No official patch has been released as of this writing, and the specific vendor or product name has not been publicly identified beyond the repository reference.

Technical Analysis

The vulnerability report, submitted by a researcher using the handle ljt12343 on Gitee, describes the issue as an "Insecure Permissions" weakness. The affected component is a Medical Management System whose source code is hosted in a repository at gitee.com/ljt12343/report. The commit hash a81df1ce700a9662cb136b27af47f4cbde64156b points to a specific version of the codebase where the permission checks for password reset functionality are missing or improperly implemented.

Insecure permissions vulnerabilities occur when an application fails to enforce proper authorization checks on sensitive operations. In this case, the password reset endpoint or function does not verify that the requesting user has the right to reset the target user's password. This could allow an unauthenticated or low-privilege attacker to send a crafted request that changes an administrator's password, effectively granting full control over the system.

The NVD entry for CVE-2025-67437 assigns a CVSS v3.1 base score of 6.5, placing it in the "Medium" severity range. The attack vector is network-based, meaning the vulnerability can be exploited remotely. The complexity is low, and no privileges are required to initiate the attack. However, the scope is unchanged, and the impact on confidentiality, integrity, and availability is rated as "None" for confidentiality, "High" for integrity, and "None" for availability, according to the CVSS vector string. This scoring indicates that the primary risk is unauthorized modification of user credentials, which could cascade into full system compromise.

It is important to note that the source material does not provide a detailed proof-of-concept or exploit code. The Gitee issue page contains only a brief description and the commit hash. The exact mechanism — whether the vulnerability lies in an API endpoint, a web form, or a database-level permission — remains unclear without deeper analysis of the source code. Additionally, the identity of the software vendor or maintainer is not disclosed, which complicates remediation efforts for organizations that may be running this system.

Mitigations & Recommendations

As of the publication date, no official patch or advisory from the vendor has been identified. Defenders who suspect they are using this Medical Management System should take the following steps:

• Identify the software: Cross-reference the commit hash a81df1ce700a9662cb136b27af47f4cbde64156b against internal asset inventories to determine if the affected system is deployed. The repository at Gitee may provide additional clues about the product name.
• Restrict network access: If the system cannot be immediately patched, limit network access to trusted IP ranges or place it behind a VPN or application-layer firewall to reduce the attack surface.
• Monitor for unauthorized password changes: Enable auditing on user account modification events, particularly password resets, and alert on anomalous activity.
• Apply a workaround: If source code access is available, review the password reset logic and add proper authorization checks, such as verifying the requesting user's role or ownership of the account before allowing the reset.
• Contact the vendor: If the vendor can be identified, request an official patch or mitigation guidance.
