Overview
CVE-2025-14051 describes a medium severity vulnerability found in youlaitech’s youlai-mall versions 1.0.0 and 2.0.0. This flaw allows remote attackers to manipulate dynamically-identified variables through specific functions, potentially leading to unauthorized actions and system compromise. The vendor has been notified but has not provided a response or patch.
Technical Details
The vulnerability resides in the getById, updateAddress, and deleteAddress functions of the /mall-ums/app-api/v1/addresses/ endpoint. An attacker can exploit this flaw by manipulating input parameters passed to these functions. Due to improper handling of dynamically-identified variables, malicious actors can potentially gain control over aspects of the application’s behavior, leading to various security risks. Proof-of-concept exploit code is publicly available, increasing the risk of exploitation in the wild.
CVSS Analysis
- CVSS Score: 6.3 (Medium)
Possible Impact
Successful exploitation of CVE-2025-14051 could lead to:
- Data Modification: Unauthorized modification or deletion of user data, particularly address information.
- Account Takeover: In some scenarios, manipulation of variables could be leveraged to gain control of user accounts.
- Information Disclosure: Sensitive information about the system or other users may be exposed.
- Potential for Remote Code Execution (Depending on Context): While not explicitly stated, the manipulation of dynamically identified variables could, in some circumstances within the application’s logic, potentially lead to remote code execution. This depends on how the manipulated variables are used within the vulnerable functions.
Mitigation or Patch Steps
As the vendor has not responded, immediate patching is not available. The following are potential mitigation steps:
- Web Application Firewall (WAF): Implement a WAF with rules to detect and block malicious requests targeting the vulnerable endpoints. Pay close attention to requests containing unusual or unexpected parameters in the
/mall-ums/app-api/v1/addresses/endpoint. - Input Validation: Thoroughly validate and sanitize all user inputs to the
getById,updateAddress, anddeleteAddressfunctions. Implement strict data type and format checking to prevent malicious data from being processed. - Code Review: Conduct a thorough code review of the affected functions to identify and fix the improper handling of dynamically-identified variables.
- Rate Limiting: Implement rate limiting on the vulnerable endpoints to reduce the potential for automated exploitation attempts.
- Monitor Logs: Closely monitor application logs for suspicious activity related to the affected endpoints.
Important Note: These mitigations provide only partial protection. A proper fix from the vendor is strongly recommended.
