medium Nessus Plugin ID 141131

Language:

Synopsis

The remote Debian host is missing a security update.

Description

This package allowed ../ directory traversal to access private resources because resource matching did not ensure that pathnames were in a canonical format.

For Debian 9 stretch, this problem has been fixed in version 0.4.0-1+deb9u2.

We recommend that you upgrade your ruby-rack-cors packages.

For the detailed security status of ruby-rack-cors please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/ruby-rack-cors

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected ruby-rack-cors package.
