A Regular Expression Denial of Service (ReDoS) vulnerability exists in Apache Superset versions 1.5.0 through 5.0.0. The vulnerability is located in the sql parse.py component, specifically within the SQL REGEX used for parsing SQL statements in the sqlparse library integration.
The affected regular expression contains overlapping disjunctions that share a common outer quantifier. An authenticated attacker can exploit this by sending a maliciously crafted input string (specifically a long sequence of backslashes or similar characters) to endpoints that process SQL queries
This issue affects Apache Superset: before 6.0.0.
Users are recommended to upgrade to version 6.0.0, which fixes the issue.
Workarounds:
● WAF Rules: Implement Web Application Firewall (WAF) rules to detect and block
requests containing excessively long sequences of backslashes or suspicious repeated
patterns in the queries.extras.where parameter.
● Rate Limiting: Ensure strict rate limiting is applied to the /api/v1/chart/data endpoint to
reduce the impact of potential attacks.
