CVE-2025-25257
CVE-2025-25257 is a security flaw in Fortinet FortiWeb, Fortinet’s business security equipment. Attackers can read or change the database behind Fortinet FortiWeb from anywhere, without logging in. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 18 Jul 2025.[1]
Fortinet FortiWeb is business software or equipment. Most families won’t have it, but attackers break into it to get inside companies, and from there to what those companies hold about their customers, patients and staff. Fortinet has published a fix or advice.
Description
CISA calls it an SQL injection in Fortinet FortiWeb. In its words: “Fortinet FortiWeb contains a SQL injection vulnerability that may allow an unauthenticated attacker to execute unauthorized SQL code or commands via crafted HTTP or HTTPs requests.”[1]
The CVE record adds: “An improper neutralization of special elements used in an SQL command ('SQL Injection') vulnerability [CWE-89] vulnerability in Fortinet FortiWeb 7.6.0 through 7.6.3, FortiWeb 7.4.0 through 7.4.7, FortiWeb 7.2.0 through 7.2.10, FortiWeb 7.0.0 through 7.0.10 allows an unauthenticated attacker to execute unauthorized SQL code or commands via crafted HTTP or HTTPs requests.”[2]
The underlying weakness is SQL injection (CWE-89), in MITRE’s list of common software weaknesses.
It scores 9.8 out of 10 on the Common Vulnerability Scoring System, which rates it critical, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it; Fortinet’s advisory has them[3]. CISA names the product as Fortinet FortiWeb.
Most families won’t have Fortinet FortiWeb; it’s for whoever looks after IT at work.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 18 Jul 2025, within a day of it being made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 8 Aug 2025 to fix it.[1]
FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at over 99%. That’s in the top 1% of the flaws it scores.[4]
CISA assesses it as automatable: attackers can run it against many targets at once.
CISA doesn’t say who was attacked, or how.
Fix
Fortinet has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.”[1]
- Check whether you use it.Fortinet FortiWeb is business software or equipment, so most families won’t have it. If you run a business, or work from home on company equipment, ask whoever looks after your IT.
- Send this page to your IT person.Ask them to confirm it’s fixed, or not in use. CISA gave US government agencies until 8 Aug 2025 to fix it.
- If it can’t be fixed, take it offline.CISA’s advice when there’s no fix is to stop using the product, or take it off the internet, until there is one.
You can’t fix someone else’s server, but you can watch for what follows a break-in like this: a breach notice, a password reset you didn’t ask for, or a scam message that knows things it shouldn’t. HARD watches for those for you and your family.
