The vulnerability identified as CVE-2023-52286 affects Tencent tdsqlpcloud versions 1.8.5 and earlier, representing a critical security flaw that exposes database credentials to unauthenticated remote attackers. This issue manifests through a specific API endpoint at index.php/api/install/get_db_info, which inadvertently provides sensitive information without requiring any authentication credentials. The vulnerability is particularly concerning as it directly enables attackers to gain unauthorized access to database configuration details, potentially compromising the entire database infrastructure.
The technical flaw stems from insufficient authentication checks within the installation and configuration API endpoints of the tdsqlpcloud platform. When an attacker sends a request to the designated endpoint, the system fails to validate the requester's credentials or authorization status, allowing immediate access to database connection parameters including usernames, passwords, and connection strings. This represents a clear violation of fundamental security principles where sensitive information is exposed through an accessible API interface. The vulnerability operates at the application layer and can be exploited remotely without any prior authentication, making it particularly dangerous in environments where such systems are exposed to untrusted networks.
The operational impact of this vulnerability extends beyond simple credential exposure, as it provides attackers with the foundational information required to launch more sophisticated attacks against the database infrastructure. Once credentials are obtained, attackers can establish direct database connections, potentially leading to data exfiltration, manipulation, or complete system compromise. The vulnerability affects the confidentiality and integrity of database systems, as unauthorized parties can access sensitive information stored within the databases. Organizations using affected versions of tdsqlpcloud face significant risk of data breaches and compliance violations, particularly in regulated environments where database security is paramount.
This vulnerability aligns with CWE-287, which addresses improper authentication issues in software systems, and demonstrates how weak authentication controls can lead to severe security consequences. The flaw also maps to ATT&CK technique T1566, specifically the use of credential harvesting through exposed services, making it a prime target for automated exploitation tools. Organizations should immediately implement mitigations including access control restrictions, network segmentation, and firewall rules to limit access to the vulnerable API endpoints. Additionally, the affected systems should be updated to versions that properly implement authentication checks and validate all incoming requests before returning sensitive information. The vulnerability underscores the importance of implementing proper security controls during application development and conducting regular security assessments to identify and remediate similar exposure points in database management systems.
