The vulnerability identified as CVE-2023-44690 represents a significant security weakness in the mycli database command-line interface tool version 1.27.0. This issue stems from inadequate encryption strength implemented within the application's configuration handling mechanism, specifically in the /mycli/config.py file. The weakness creates an exploitable condition where attackers can potentially access sensitive information that should remain protected through proper cryptographic measures. The vulnerability affects users who rely on mycli for database administration tasks and exposes them to risks associated with data interception and unauthorized access to configuration parameters.
The technical flaw manifests in the insufficient cryptographic strength used for encrypting sensitive data within the mycli configuration system. When the application processes configuration files through /mycli/config.py, it fails to implement adequate encryption algorithms or key lengths that would prevent unauthorized access to stored credentials, connection parameters, or other sensitive information. This weakness likely stems from the use of deprecated or weak cryptographic primitives that do not meet current security standards for protecting sensitive data at rest. The vulnerability falls under the broader category of weak cryptographic implementations that are commonly classified under CWE-327, which addresses the use of weak or broken cryptographic algorithms.
The operational impact of this vulnerability extends beyond simple information disclosure, as it creates potential attack vectors for malicious actors seeking to compromise database environments. Attackers who can exploit this weakness gain access to configuration data that may contain database connection strings, user credentials, or other sensitive parameters that could enable further attacks against the underlying database systems. The vulnerability particularly affects environments where mycli is used for database administration, as the compromised configuration data could provide attackers with direct access paths to production databases. This weakness aligns with ATT&CK technique T1552.001, which covers the exploitation of credentials in files, and represents a critical gap in the security posture of database administration tools.
Mitigation strategies for CVE-2023-44690 should prioritize immediate updates to the mycli application to versions that implement proper cryptographic strength for configuration data encryption. Organizations should also implement additional security controls such as restricting file system access to the configuration files, employing proper access controls for sensitive data, and considering alternative database administration tools that demonstrate stronger cryptographic practices. Security teams should conduct thorough audits of all database administration tools in use to identify similar weaknesses in encryption implementation and establish policies for regular security assessments of development and operational tools. The vulnerability underscores the importance of maintaining up-to-date cryptographic implementations and proper security hygiene in database administration environments where sensitive information is handled regularly.
