[R1] Nessus Version 10.7.3 Fixes Multiple Vulnerabilities

High
← View More Security Advisories

Synopsis

Two separate vulnerabilities were discovered, reported and fixed:

  • When installing Nessus to a directory outside of the default location on a Windows host, Nessus versions prior to 10.7.3 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location. - CVE-2024-3289

  • A race condition vulnerability exists where an authenticated, local attacker on a Windows Nessus host could modify installation parameters at installation time, which could lead to the execution of arbitrary code on the Nessus host. - CVE-2024-3290

Solution

Tenable has released Nessus 10.7.3 to address these issues. The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus).
