CVE-2023-0524
As part of our Security Development Lifecycle, a potential privilege escalation issue was identified internally.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.64%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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 in feed serial numbers equal to or greater than #202212212055.
