CVE-2022-40684 is a critical vulnerability affecting Fortinet's FortiOS, FortiProxy, and FortiSwitchManager. This vulnerability allows an unauthenticated attacker to perform operations on the administrative interface via specially crafted HTTP or HTTPS requests. The flaw exists in FortiOS versions 7.2.0 through 7.2.1 and 7.0.0 through 7.0.6, as well as in FortiProxy and FortiSwitchManager versions 7.2.0 and 7.0.0 through 7.0.6.
With a CVSS score of 9.8, this vulnerability is classified as critical due to its potential impact on confidentiality, integrity, and availability. The attack vector is network-based with low complexity, meaning that attackers do not require special privileges or user interaction to exploit this vulnerability.
Risk to organizations includes unauthorized access to the administrative interface, potentially leading to complete control over compromised systems. Given the severity and the known exploitation status of this vulnerability, organizations should prioritize patching immediately.
This vulnerability is actively exploited in the wild, and its inclusion in the Known Exploited Vulnerabilities (KEV) catalog emphasizes the urgency for organizations to take action.
Vulnerability Details
The vulnerability allows an attacker to bypass authentication by using an alternate path or channel (CWE-288). The affected products include FortiOS, FortiProxy, and FortiSwitchManager, specifically versions 7.2.0 through 7.2.1 and 7.0.0 through 7.0.6.
The official CVSS score is 9.8, indicating a critical severity level. The potential impacts of this vulnerability are high across confidentiality, integrity, and availability.
Technical Analysis
The root cause of this vulnerability lies in an improper implementation of authentication mechanisms within the affected Fortinet products. It enables attackers to send specially crafted requests to the administrative interface without proper authentication.
The attack vector is network-based, which means that attackers can exploit this vulnerability remotely. The attack complexity is low, as no special conditions are required for the attack to succeed. Additionally, no privileges are required and no user interaction is necessary.
The potential impacts are severe, with high risks to confidentiality, integrity, and availability. An attacker exploiting this vulnerability could gain full administrative access, allowing them to manipulate settings and data.
Risk & Impact Analysis
Real-world risk includes unauthorized access to sensitive data and control over network devices. The blast radius is extensive, affecting multiple products across various deployments. Organizations using the affected Fortinet products must understand that the urgency for remediation is high due to the critical nature of this vulnerability.
Given the CVSS score and active exploitation status, organizations should prioritize patching immediately. The inclusion in the KEV catalog further underscores the need for prompt action to mitigate this risk.
