Overview
CVE-2025-14052 details a medium severity access control vulnerability found in youlaitech youlai-mall versions 1.0.0 and 2.0.0. The vulnerability resides within the getMemberById function of the /mall-ums/app-api/v1/members/ endpoint. Successful exploitation of this vulnerability allows remote attackers to bypass intended access controls, potentially gaining unauthorized access to sensitive member information or performing actions on behalf of other users.
Technical Details
The vulnerability lies in the insufficient validation or sanitization of the memberId argument passed to the getMemberById function. By manipulating this parameter, an attacker can potentially retrieve information or execute actions related to other user accounts without proper authorization. The vulnerability exists because the system fails to adequately verify if the requesting user has the necessary permissions to access the data associated with the provided memberId. The public availability of the exploit increases the risk of malicious actors exploiting this flaw.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-14052 is 6.3, indicating a MEDIUM severity. This score reflects the following factors:
- Attack Vector (AV): Network (N) – The vulnerability is remotely exploitable.
- Attack Complexity (AC): Low (L) – Exploitation requires minimal skill.
- Privileges Required (PR): None (N) – No privileges are required to exploit the vulnerability.
- User Interaction (UI): None (N) – No user interaction is required.
- Scope (S): Unchanged (U)
- Confidentiality Impact (C): Low (L) – Limited sensitive data disclosure.
- Integrity Impact (I): Low (L) – Limited alteration of data is possible.
- Availability Impact (A): None (N) – No impact to availability.
Possible Impact
Successful exploitation of CVE-2025-14052 could lead to the following:
- Unauthorized Access to Member Data: Attackers could retrieve sensitive information such as addresses, phone numbers, email addresses, and purchase history of other users.
- Account Takeover (Potentially): Depending on the application’s functionality, attackers might be able to leverage the vulnerability to perform actions on behalf of other users, potentially leading to account takeover.
- Data Manipulation: While rated as Low impact on integrity, it may be possible to modify certain user settings or information depending on the functionality associated with the
getMemberByIdfunction.
Mitigation and Patch Steps
Unfortunately, the vendor (youlaitech) has not responded to vulnerability disclosures and has not released an official patch. Therefore, immediate action is crucial. Suggested mitigation strategies include:
- Input Validation and Sanitization: Implement strict input validation and sanitization for the
memberIdparameter. Ensure that the provided ID corresponds to an actual existing member and that the requesting user has the appropriate permissions to access that member’s information. - Access Control Checks: Implement robust access control checks before retrieving or manipulating member data. Verify that the authenticated user has the necessary authorization to access the requested resource.
- Rate Limiting: Implement rate limiting on the
/mall-ums/app-api/v1/members/endpoint to prevent attackers from rapidly attempting to exploit the vulnerability. - Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) and configure rules to detect and block malicious requests attempting to exploit the vulnerability.
- Monitor Traffic: Closely monitor traffic to the
/mall-ums/app-api/v1/members/endpoint for suspicious activity. - Consider Disabling Endpoint: If possible, consider disabling the vulnerable endpoint if it is not critical to the application’s functionality. This is an extreme measure but might be necessary if other mitigations are insufficient.
