Miggo AIRoot Cause AnalysisThe vulnerability lies in the SQL sanitization logic used by the OpenTelemetry Java Instrumentation agent for JDBC. The root cause is the improper handling of passwords within SQL statements, specifically CONNECT statements where the password might be double-quoted. The investigation of the provided patch commit 7ac7fa6fda6c2e3b65bc5d3c6eba050311a49511 reveals significant changes to the JFlex files (SqlSanitizer.jflex, SqlSanitizerWithSummary.jflex) that define the sanitization rules. The previous logic for handling the CONNECT keyword was a simplistic approach that sanitized the entire statement, which proved to be insufficient and failed to handle certain cases like double-quoted passwords. The patch replaces this with a more sophisticated, stateful parsing mechanism that correctly identifies and redacts keywords like PASSWORD and IDENTIFIED BY while being aware of the statement context. The entry points for this vulnerable logic are the analyze and analyzeWithSummary methods within the io.opentelemetry.instrumentation.api.incubator.semconv.db.SqlQueryAnalyzer class. These methods are called by the JDBC auto-instrumentation to sanitize SQL queries before they are exported as trace attributes. Therefore, during exploitation, these two functions would be present in the runtime profile as they process the malicious SQL string containing the clear-text password.
