Improper Parameter Handling in Fortinet FortiWeb Affects Security

CVE-2025-52970

What is CVE-2025-52970?

CVE-2025-52970 is a significant vulnerability identified in Fortinet's FortiWeb, a web application firewall designed to protect web applications from various cyber threats, including attacks aimed at disrupting services or stealing data. This vulnerability arises from improper handling of parameters in specific versions of FortiWeb (versions 7.6.3 and below, 7.4.7 and below, 7.2.10 and below, and 7.0.10 and below). It enables an unauthenticated remote attacker with non-public information about the device and targeted user to gain administrative privileges. Such a compromise can severely hinder the integrity and confidentiality of the protected web applications, allowing attackers to manipulate settings or gain access to sensitive information.

Potential Impact of CVE-2025-52970

1. Unauthorized Administrative Access: The vulnerability allows attackers to gain admin privileges, which could lead to complete control over the FortiWeb device, allowing them to reconfigure security settings, disable protections, or execute malicious commands.

2. Data Breach Risk: With heightened privileges, an attacker can access sensitive information intercepted by the web application firewall, potentially leading to data theft and exposing confidential organizational data.

3. Increased Attack Surface: The exploitation of this vulnerability could be leveraged as a pivot point for further network intrusions, increasing the risk of widespread system compromise and the potential deployment of additional malware or ransomware across the organization.
