Safety researchers have recognized a extreme pre-authentication SQL injection vulnerability in Fortinet\u2019s FortiWeb Material Connector, designated as CVE-2025-25257, that permits unauthenticated attackers to execute unauthorized SQL instructions and probably obtain distant code execution. <\/p>\n

The vulnerability impacts a number of variations of FortiWeb, together with 7.6.0 via 7.6.3, 7.4.0 via 7.4.7, 7.2.0 via 7.2.10, and seven.0.0 via 7.0.10, with patches accessible in newer variations. <\/p>\n

FortiWeb\u2019s Material Connector serves as integration middleware between FortiWeb internet utility<\/a> firewalls and different Fortinet ecosystem merchandise, enabling dynamic safety coverage updates based mostly on real-time infrastructure modifications and risk intelligence.<\/p>\n

Technical Particulars of the SQL Injection Flaw<\/strong><\/h2>\n
\n
\"\"\/<\/figure>\n<\/div>\n

The vulnerability stems from improper enter sanitization within the get_fabric_user_by_token<\/code> perform inside FortiWeb\u2019s authentication mechanism. <\/p>\n

Researchers found that the perform instantly incorporates user-controlled enter from HTTP Authorization headers into SQL queries with out correct validation or escaping. <\/p>\n

The susceptible code makes use of a format string strategy, establishing queries like choose id from fabric_user.user_table the place token='%s'<\/code> the place the %s<\/code> placeholder is changed with attacker-controlled knowledge from the Authorization Bearer token.<\/p>\n

\n
\"\"\/<\/figure>\n<\/div>\n

The authentication course of extracts tokens from Authorization headers utilizing the format Bearer %128s<\/code>, which presents each alternatives and constraints for exploitation. <\/p>\n

Whereas the sscanf perform limits enter to 128 characters and stops parsing on the first area character, attackers can bypass these restrictions utilizing MySQL remark syntax (\/**\/<\/code>) to exchange areas of their injection payloads. <\/p>\n

This permits for advanced SQL injection<\/a> assaults regardless of the obvious enter limitations.<\/p>\n

Fortinet has addressed the vulnerability in patched variations by changing the susceptible format string queries with ready statements utilizing MySQL\u2019s mysql_stmt_prepare<\/code> perform. <\/p>\n

The up to date implementation makes use of parameterized queries with placeholders (SELECT id FROM fabric_user.user_table WHERE token = ?<\/code>) that correctly separate SQL code from person knowledge, stopping injection assaults.<\/p>\n

Escalation from SQL Injection to Distant Code Execution<\/strong><\/h2>\n

Safety researchers demonstrated how this SQL injection vulnerability may be escalated to realize full distant code execution via a classy assault chain. <\/p>\n

The exploitation leverages MySQL\u2019s INTO OUTFILE<\/code> assertion to put in writing arbitrary information to the goal system, mixed with Python\u2019s site-specific configuration hooks for code execution.
Key steps within the assault chain embody:<\/p>\n
