The vulnerability identified as CVE-2017-10842 represents a critical SQL injection flaw within the baserCMS content management system affecting versions 3.0.14 and earlier, as well as 4.0.5 and earlier. This vulnerability resides in the application's handling of user input within database queries, creating an exploitable condition that enables remote attackers to manipulate the underlying database infrastructure. The unspecified vectors suggest that the flaw could potentially be triggered through multiple entry points within the CMS framework, making the attack surface broader and more difficult to predict.
This vulnerability directly maps to CWE-89 which defines SQL injection as the insertion of malicious SQL code into input fields for execution by the database engine. The flaw operates by failing to properly sanitize or escape user-supplied data before incorporating it into SQL query strings, allowing attackers to inject their own SQL commands that execute with the privileges of the database user account. The remote nature of the exploit means that attackers do not need physical access to the system and can leverage the vulnerability through network-based attacks.
The operational impact of this vulnerability is severe as it provides attackers with the capability to execute arbitrary SQL commands against the affected database. This could enable full database compromise including data exfiltration, data manipulation, privilege escalation, and potentially complete system takeover. Attackers could extract sensitive information such as user credentials, personal data, and application configuration details. The vulnerability also poses risks to data integrity and availability, as malicious actors could modify or delete critical database records, potentially causing service disruption and data loss that could affect business operations and regulatory compliance.
Mitigation strategies for CVE-2017-10842 should prioritize immediate patching of affected baserCMS installations to versions that address the SQL injection vulnerability. Organizations should implement proper input validation and parameterized queries throughout the application codebase to prevent similar issues in the future. Network segmentation and access controls should be enforced to limit exposure of database systems. Additionally, implementing web application firewalls and intrusion detection systems can help detect and prevent exploitation attempts. Regular security assessments and penetration testing should be conducted to identify and remediate similar vulnerabilities across the entire application infrastructure. The ATT&CK framework categorizes this vulnerability under T1190 - Exploit Public-Facing Application, highlighting the importance of maintaining up-to-date security patches and implementing proper network security controls to prevent unauthorized access to vulnerable systems.
