Fortinet has launched fixes for a essential safety flaw impacting FortiWeb that would allow an unauthenticated attacker to run arbitrary database instructions on inclined situations.
Tracked as CVE-2025-25257, the vulnerability carries a CVSS rating of 9.6 out of a most of 10.0.
“An improper neutralization of particular components utilized in an SQL command (‘SQL Injection’) vulnerability [CWE-89] in FortiWeb might permit an unauthenticated attacker to execute unauthorized SQL code or instructions by way of crafted HTTP or HTTPs requests,” Fortinet mentioned in an advisory launched this week.
The shortcoming impacts the next variations –
- FortiWeb 7.6.0 by way of 7.6.3 (Improve to 7.6.4 or above)
- FortiWeb 7.4.0 by way of 7.4.7 (Improve to 7.4.8 or above)
- FortiWeb 7.2.0 by way of 7.2.10 (Improve to 7.2.11 or above)
- FortiWeb 7.0.0 by way of 7.0.10 (Improve to 7.0.11 or above)
Kentaro Kawane from GMO Cybersecurity, who was lately credited with reporting a set of essential flaws in Cisco Id Providers and ISE Passive Id Connector (CVE-2025-20286, CVE-2025-20281, and CVE-2025-20282), has been acknowledged for locating the problem.
In an evaluation printed at this time, watchTowr Labs mentioned the issue is rooted in a operate referred to as “get_fabric_user_by_token” that is related to the Material Connector element, which acts as a bridge between FortiWeb and different Fortinet merchandise.
The operate, in flip, is invoked from one other operate named “fabric_access_check,” that is referred to as from three totally different API endpoints: “/api/material/gadget/standing,” “/api/v[0-9]/material/widget/[a-z]+,” and “/api/v[0-9]/material/widget.”
The difficulty is that attacker-controlled enter – handed by way of a Bearer token Authorization header in a specifically crafted HTTP request – is handed on to an SQL database question with out sufficient sanitization to ensure that it isn’t dangerous and doesn’t embody any malicious code.
The assault could be prolonged additional by embedding a SELECT … INTO OUTFILE assertion to put in writing the outcomes of command execution to a file within the underlying working system by profiting from the truth that the question is run because the “mysql” consumer.
“The brand new model of the operate replaces the earlier format-string question with ready statements – an affordable try to stop simple SQL injection,” safety researcher Sina Kheirkhah mentioned.
As non permanent workarounds till the mandatory patches could be utilized, customers are really helpful to disable HTTP/HTTPS administrative interface.
With flaws in Fortinet units having been exploited by menace actors prior to now, it is important that customers transfer shortly to replace to the most recent model to mitigate potential dangers.
