"Fortinet Patches High-Severity Authentication Bypass Vulnerability in FortiOS"
Cybersecurity solutions provider Fortinet recently announced patches for multiple vulnerabilities across its products, including a high-severity authentication bypass impacting FortiOS and FortiProxy. Tracked as CVE-2022-35843 (CVSS score of 7.7), the authentication bypass was identified in the SSH login component of FortiOS. Fortinet noted that the bug can only be triggered when Radius authentication is used. Fortinet noted that an authentication bypass by assumed-immutable data vulnerability in the FortiOS SSH login component may allow a remote and unauthenticated attacker to login into the device via sending a specially crafted Access-Challenge response from the Radius server. The vulnerability impacts FortiOS versions 7.2.x, 7.0.x, 6.4.x, 6.2.x, and 6.0.x, and FortiProxy versions 7.0.x, 2.0.x, and 1.2.x. Patches were included in FortiOS versions 7.2.2, 7.0.8, and 6.4.10 and in FortiProxy versions 7.0.7 and 2.0.11. This week, Fortinet also announced patches for two medium-severity vulnerabilities in FortiADC (Application Delivery Controller), which ensures application availability, optimization, and security. Fortinet noted that the first bug (CVE-2022-33876) cumulates multiple input validation issues leading to information disclosure via crafted HTML requests, while the second (CVE-2022-33875) is described as an improper neutralization of special elements leading to SQL injection. Several low-severity vulnerabilities have also been resolved.
