Fortinet Patches 6 High-Severity Vulnerabilities

Fortinet on Tuesday informed customers about 16 vulnerabilities discovered in the company’s products, including six flaws that have been assigned a ‘high’ severity rating.

Fortinet on Tuesday informed customers about 16 vulnerabilities discovered in the company’s products, including six flaws that have been assigned a ‘high’ severity rating.

One of the high-severity issues affects FortiTester and it allows an authenticated attacker to execute commands via specially crafted arguments to existing commands. FortiSIEM is affected by a vulnerability that allows a local attacker with command-line access to perform operations on the Glassfish server directly via a hardcoded password.

The remaining high-severity flaws are stored and reflected cross-site scripting (XSS) bugs. They impact FortiADC, FortiDeceptor, FortiManager and FortiAnalyzer. Some of them can be exploited remotely without authentication.

Medium- and low-severity vulnerabilities have been patched in FortiOS, FortiTester, FortiSOAR, FortiMail, FortiEDR CollectorWindows, FortiClient for Mac, and FortiADC.

These security holes can be exploited for privilege escalation, XSS attacks, obtaining sensitive information, DoS attacks, bypassing protections, changing settings, and executing arbitrary commands.

Additional information can be found in the advisories published by Fortinet. 

Fortinet recently warned customers about an actively exploited vulnerability affecting FortiOS, FortiProxy, and FortiSwitchManager products. The flaw, tracked as CVE-2022-40684, was initially exploited in one attack, but mass exploitation attempts were observed soon after disclosure and some users were slow to deploy the available patches.
