Fortinet Patches High-Severity Vulnerabilities in Several Products

Fortinet published security advisories this week to inform customers about vulnerabilities affecting several of the company’s products.

The cybersecurity firm’s latest batch of monthly advisories describe roughly a dozen vulnerabilities identified in FortiADC, FortiAnalyzer, FortiManager, FortiOS, FortiProxy, FortiClient, FortiDeceptor, FortiEDR, FortiNAC, FortiSwitch, FortiRecorder, and FortiVoiceEnterprise products.

Four CVEs have been assigned a “high” severity rating. This includes CVE-2022-26117, which affects FortiNAC and allows an attacker to access MySQL databases due to an unprotected root account.

Another high-severity flaw is a stack-based buffer overflow that allows arbitrary code or command execution. This issue, tracked as CVE-2021-43072, affects FortiAnalyzer, FortiManager, FortiOS and FortiProxy.

A “high severity” rating has also been assigned to CVE-2022-30302, a CVE assigned to multiple path traversal bugs in the FortiDeceptor admin interface that can be exploited by a remote attacker to retrieve and delete arbitrary files from the underlying file system.

A directory traversal issue affecting FortiClient for Windows, CVE-2021-41031, is also “high severity”. It allows a local attacker to escalate privileges.

Roughly half of the vulnerabilities were reported to Fortinet by external researchers — the rest were discovered internally. Only a couple of the flaws — rated “medium” and “low” — can be exploited without authentication.

Patches are available for all of these vulnerabilities. While none of the flaws sounds particularly dangerous, it’s not uncommon for threat actors to target Fortinet products in their attacks so users should update their systems as soon as possible.
