Overview
CVE-2025-14086 details an improper access control vulnerability affecting youlaitech youlai-mall versions 1.0.0 and 2.0.0. This flaw allows for unauthorized access to sensitive resources due to insufficient validation of user-supplied input. The vulnerability resides within the /app-api/v1/members/openid/ endpoint, specifically through manipulation of the openid parameter. A publicly available exploit exists, increasing the risk of exploitation. The vendor was contacted regarding this issue but has not provided a response.
Technical Details
The vulnerability stems from a lack of proper input sanitization and authorization checks on the openid parameter within the /app-api/v1/members/openid/ endpoint. An attacker can manipulate this parameter to potentially bypass access controls and gain unauthorized access to user accounts or other sensitive data associated with different openid values. The exact function affected is currently unknown, but the publicly available exploit suggests that modifying the openid value can lead to privilege escalation or data leakage. The ability to trigger this vulnerability remotely significantly increases its potential impact.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-14086 a score of 6.3 (Medium). This score reflects the following characteristics:
- Attack Vector (AV): Network (N) – The vulnerability can be exploited remotely.
- Attack Complexity (AC): Low (L) – The conditions for exploitation are relatively straightforward.
- Privileges Required (PR): None (N) – No privileges are required to exploit the vulnerability.
- User Interaction (UI): None (N) – No user interaction is required to trigger the vulnerability.
- Scope (S): Unchanged (U) – An exploited vulnerability can only affect resources managed by the same security authority.
- Confidentiality Impact (C): Partial (L) – There is a limited impact on data confidentiality.
- Integrity Impact (I): Partial (L) – There is a limited impact on data integrity.
- Availability Impact (A): None (N) – There is no impact on system availability.
While the CVSS score is Medium, the existence of a publicly available exploit raises the actual risk level.
Possible Impact
Successful exploitation of CVE-2025-14086 could lead to the following consequences:
- Unauthorized Access to User Accounts: Attackers could potentially gain access to user accounts by manipulating the
openidparameter. - Data Leakage: Sensitive user data associated with different
openidvalues might be exposed. - Privilege Escalation: Attackers might be able to elevate their privileges within the application.
- Reputational Damage: A successful attack could damage the reputation of youlaitech and youlai-mall.
Mitigation and Patch Steps
Given the vendor’s lack of response, immediate mitigation steps are crucial. The following actions are recommended:
- Input Validation: Implement strict input validation and sanitization on the
openidparameter within the/app-api/v1/members/openid/endpoint. Ensure that theopenidvalue conforms to expected formats and patterns. - Authorization Checks: Enforce robust authorization checks to verify that the user associated with the provided
openidhas the necessary permissions to access the requested resources. - Web Application Firewall (WAF): Deploy a WAF to detect and block malicious requests targeting the vulnerable endpoint. Configure the WAF to filter requests containing suspicious
openidvalues. - Rate Limiting: Implement rate limiting to prevent attackers from rapidly testing different
openidvalues. - Monitor for Suspicious Activity: Continuously monitor application logs for any suspicious activity related to the
/app-api/v1/members/openid/endpoint. - Consider Third-Party Patches (if available): Check for community-developed patches or workarounds for this vulnerability.
- Isolate the Vulnerable Endpoint (if possible): If the vulnerable endpoint is not critical, consider temporarily disabling it until a proper fix can be implemented.
