Cortex XDR Vulnerability Assessment - Linux Backporting Security Fixes

L2 Linker

Dear community

 

When using the Vulnerability Assessment with Linux hosts, the results may include a lot of false positives.

Distributions which are backporting security fixes (CentOS / Debian) do may not change the App Version when they got patched.

https://access.redhat.com/security/updates/backporting

 

"Backporting has a number of advantages for customers, but it can create confusion when it is not understood. Customers need to be aware that just looking at the version number of a package will not tell them if they are vulnerable or not"

 

"We also supply OVAL definitions (machine-readable versions of our advisories) that third-party vulnerability tools can use to determine the status of vulnerabilities, even when security fixes have been backported."

 

I didn't see much in the documentation, and I'm not sure if this is "working as expected" or if there is a way to improve the configuration for better detection.

 

Cheers

Fabian
