high Nessus Plugin ID 170885


The remote Debian host is missing one or more security-related updates.


The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3298 advisory.

- A directory traversal vulnerability exists in rack < 2.2.0 that allows an attacker perform directory traversal vulnerability in the Rack::Directory app that is bundled with Rack which could result in information disclosure. (CVE-2020-8161)

- A reliance on cookies without validation/integrity check security vulnerability exists in rack < 2.2.3, rack < 2.1.4 that makes it is possible for an attacker to forge a secure or host-only cookie prefix.

- Aaron Patterson reports: (CVE-2022-44570, CVE-2022-44571, CVE-2022-44572)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
