February 20, 2023

Severity

High

Analysis Summary

CVE-2022-38375 CVSS:9.1

Fortinet FortiNAC could allow a remote attacker to bypass security restrictions, caused by improper authorization. By sending a specially-crafted HTTP POST request, an attacker could exploit this vulnerability to carry out some administrative operations over the FortiNAC instance.

CVE-2022-40678 CVSS:7.4

Fortinet FortiNAC could allow a local attacker to obtain sensitive information, caused by insufficiently protected credentials. An attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.

CVE-2022-39954 CVSS:7.3

Fortinet FortiNAC is vulnerable to an XML external entity injection (XXE) attack when processing XML data, caused by a weakly configured XML parser. By using specially-crafted XML content in the configuration file, a remote attacker could exploit this vulnerability to read arbitrary files, cause a denial of service, conduct an SSRF attack, or achieve other system impacts.

CVE-2022-40675 CVSS:6.5

Fortinet FortiNAC is vulnerable to a man-in-the-middle attack, caused by cryptographic issues. A remote attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to decrypt and forge protocol communication messages.

CVE-2022-38376 CVSS:6.1

Fortinet FortiNAC is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the FortiNAC portal UI. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim’s Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim’s cookie-based authentication credentials.

CVE-2022-40677 CVSS:7.2

Fortinet FortiNAC could allow a remote authenticated attacker to execute arbitrary commands on the system, caused by improper neutralization of argument delimiters in a command. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary commands on the system.

CVE-2022-39952 CVSS:9.8

Fortinet FortiNAC could allow a remote attacker to execute arbitrary code on the system, caused by a external control of file name or path vulnerability. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
