The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3877 advisory.
------------------------------------------------------------------------- Debian LTS Advisory DLA-3877-1 [email protected] https://www.debian.org/lts/security/ Jochen Sprickerhof September 05, 2024 https://wiki.debian.org/LTS
-------------------------------------------------------------------------
Package : ruby-sinatra Version : 2.0.8.1-2+deb11u1 CVE ID : CVE-2022-29970 CVE-2022-45442 Debian Bug : 1014717 1070953
Sinatra is an open source web framework for Ruby programming language.
CVE-2022-29970
A file traversal vulnerability was discovered. We now validate that any expanded paths match the allowed `public_dir` when serving static files.
CVE-2022-45442
It was discovered that there was a potential reflected file download (RFD) vulnerability. A Content-Disposition HTTP header was being incorrectly derived from a potentially user-supplied filename.
For Debian 11 bullseye, these problems have been fixed in version 2.0.8.1-2+deb11u1.
We recommend that you upgrade your ruby-sinatra packages.
For the detailed security status of ruby-sinatra please refer to its security tracker page at:
