Critical
← View More Security Advisories

Synopsis

As part of our Security Development Lifecycle, a potential privilege escalation issue was identified internally. This could allow a malicious actor with sufficient permissions to modify environment variables and abuse an impacted plugin in order to escalate privileges.

We have resolved the issue and also made several defense-in-depth fixes alongside. While the probability of successful exploitation is low, Tenable is committed to securing our customers’ environments and our products. The updates have been distributed via the Tenable plugin feed.

Solution

Tenable has released updates to plugins to resolve the issue as well as the associated defense-in-depth fixes. The updates have been distributed to the affected products via the Tenable plugin feed in feed serial numbers equal to or greater than #202212212055.

This page contains information regarding security vulnerabilities that may impact Tenable's products. This may include issues specific to our software, or due to the use of third-party libraries within our software. Tenable strongly encourages users to ensure that they upgrade or apply relevant patches in a timely manner.

Tenable takes product security very seriously. If you believe you have found a vulnerability in one of our products, we ask that you please work with us to quickly resolve it in order to protect customers.
