Researchers disclosed CVE-2025-25257, a pre-authentication SQL injection flaw in the Fortinet FortiWeb Fabric Connector that can be chained to achieve remote code execution on affected systems. Public write-ups from WatchTowr Labs and Summoning Team describe the issue as reachable without authentication, raising the risk that internet-exposed FortiWeb deployments could be compromised before defenders can intervene.
The disclosures indicate the vulnerability affects the Fabric Connector component and allows an attacker to move from SQL injection to full code execution, potentially giving control over the appliance or its underlying environment. While the referenced materials provide limited remediation detail in the supplied content, the publication of technical research and exploit methodology increases the urgency for organizations using FortiWeb to identify exposed instances, review vendor guidance for CVE-2025-25257, and prioritize patching or mitigation.
