Fortinet Fortiweb 7.0.0 – 7.0.11
Raw vector
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-52970 is a high-severity Improper Handling of Parameters (CWE-233) vulnerability in Fortinet Fortiweb. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-52970 is an improper parameter handling flaw, tracked under CWE-233, that affects Fortinet FortiWeb web application firewalls in versions 7.6.3 and earlier, 7.4.7 and earlier, 7.2.10 and earlier, and 7.0.10 and earlier. The issue resides in the handling of specially crafted requests and can be triggered when an attacker possesses non-public device and user details.
An unauthenticated remote attacker who already holds limited target-specific information can exploit the flaw over the network to obtain administrative privileges on the device. The CVSS 8.1 rating reflects the high impact on confidentiality, integrity, and availability despite the high attack complexity and lack of required credentials.
The Fortinet advisory FG-IR-25-448 recommends applying the vendor-supplied patches for the listed FortiWeb branches; no other mitigation steps are detailed in the reference materials.
EPSS for the CVE rose from a low baseline to a peak of 0.4130 before settling at the current value of 0.3051, indicating that exploitation interest increased after public disclosure.

Security testing can detect missing-parameter issues but does not prevent them at design time.
Secure development lifecycle includes input validation and parameter handling requirements that reduce improper parameter handling.
Application security requirements explicitly call for validation of inputs and parameters, mitigating missing or undefined arguments.
Secure coding standards directly address proper handling of function parameters and input validation.
