Attack activity surged against CVE-2025-25257, a critical SQL injection flaw in Fortinet FortiWeb that can enable authentication bypass and remote code execution. The vulnerability is rated CVSS 9.8 and affects multiple FortiWeb release branches, with public disclosure followed quickly by observed exploitation attempts beginning days later. Security monitoring reported that scanning and attack traffic increased notably, indicating rapid weaponization of the flaw after disclosure.
Observed exploitation attempts targeted the FortiWeb endpoint /api/fabric/device/status and injected SQL payloads through the Authorization header's Bearer token field. Attack traffic was seen from multiple countries, led by the United States, followed by France, Japan, Germany, and the Netherlands. Organizations running affected FortiWeb versions have been urged to upgrade immediately to vendor-fixed releases to reduce exposure to unauthenticated compromise.

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.

Fortinet FortiWeb has been hit by multiple serious vulnerabilities, including **`CVE-2025-58034`**, an authenticated OS command injection flaw, and **`CVE-2025-25257`**, a pre-authentication SQL injection issue in the Fabric Connector component that can lead to remote code execution. Reporting indicated the command injection bug was under active exploitation, while public advisories described the weakness as enabling attackers to execute operating system commands on affected appliances. The SQL injection flaw affects FortiWeb Fabric Connector versions across the 7.0 to 7.6.x range and is notable because exploitation does not require prior authentication. Public exploit and detection material quickly emerged for **`CVE-2025-25257`**, with GitHub repositories publishing proof-of-concept code and exploitation demonstrations, alongside production-focused detection engineering content to help defenders identify abuse. The combination of active exploitation reporting, internet-facing exposure tracking, and readily available offensive tooling raises the risk for organizations using FortiWeb, particularly where management interfaces or vulnerable connector functionality are exposed.

Attackers are actively exploiting a command injection vulnerability in Fortinet FortiWeb, tracked as CVE-2025-58034, which allows authenticated users to execute unauthorized code on affected systems. The flaw, caused by improper neutralization of special elements in the `policy_scripting_post_handler` method, enables code execution as root via crafted HTTP requests or CLI commands. Fortinet released patches for affected FortiWeb versions between October 23 and 31, 2025, but did not publicly disclose the vulnerability at the time. The issue was privately reported by a Trend Micro researcher, and both Fortinet and CISA have confirmed active exploitation, with CISA adding the CVE to its Known Exploited Vulnerabilities catalog and mandating rapid remediation for US federal agencies. Security researchers warn that proof-of-concept code for CVE-2025-58034 may soon be publicly available, increasing the risk of widespread attacks. There is currently no workaround for this vulnerability, and organizations are urged to upgrade to the fixed FortiWeb versions immediately and check for signs of compromise. The vulnerability requires authentication to exploit, but successful exploitation grants attackers root-level access. The disclosure timeline shows the vulnerability was reported in June 2025 and publicly disclosed in November 2025, with coordinated advisories from both Fortinet and the Zero Day Initiative.
