The vulnerability identified as CVE-2019-11343 affects Torpedo Query versions prior to 2.5.3 and stems from improper handling of the LIKE operator within the ConditionBuilder.java, LikeCondition.java, and NotLikeCondition.java components. This flaw represents a significant security concern as it directly impacts how database query conditions are constructed and executed within applications that utilize the Torpedo Query framework. The issue manifests when developers employ the LIKE operator in their database queries, which is a fundamental operation for pattern matching and text searching in relational databases.
The technical flaw lies in the insufficient sanitization and validation of user input when constructing LIKE conditions within the Torpedo Query library. When developers incorporate user-supplied data into LIKE expressions without proper escaping or parameterization, the framework fails to adequately protect against malicious input that could be interpreted as SQL syntax. This vulnerability creates an environment where crafted input can manipulate the intended query structure, potentially allowing attackers to inject arbitrary SQL commands or alter query behavior. The flaw specifically affects the ConditionBuilder component which is responsible for constructing database query conditions, and the LikeCondition and NotLikeCondition classes that handle pattern matching operations.
The operational impact of this vulnerability extends beyond simple data manipulation as it can enable attackers to perform unauthorized database access, data exfiltration, and potentially full system compromise depending on the database permissions and application architecture. An attacker who can influence query construction through user input may exploit this weakness to bypass authentication mechanisms, extract sensitive information from databases, or even execute destructive operations. The vulnerability is particularly concerning because LIKE operators are commonly used in applications for search functionality, user authentication, and data filtering operations, making it a frequent target for exploitation. This weakness can be leveraged in various attack scenarios including blind SQL injection, where the attacker gradually discovers information through response variations, and classic SQL injection where direct command execution is possible.
Mitigation strategies for CVE-2019-11343 primarily involve upgrading to Torpedo Query version 2.5.3 or later, which includes proper input sanitization and validation for LIKE operators. Organizations should also implement comprehensive input validation and parameterized queries to prevent similar vulnerabilities in other components. The fix aligns with security best practices outlined in CWE-89, which addresses SQL injection vulnerabilities, and follows ATT&CK techniques related to command injection and credential access. Security teams should conduct thorough code reviews focusing on query construction components and implement automated testing to detect similar issues in custom code. Additionally, database administrators should enforce principle of least privilege for database accounts and implement proper monitoring to detect anomalous query patterns that might indicate exploitation attempts. The vulnerability demonstrates the critical importance of proper input handling in database query frameworks and highlights the need for robust security measures in application development lifecycle processes.
