The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has pcs packages installed that are affected by multiple vulnerabilities:

  - Sinatra rack-protection versions 1.5.4 and 2.0.0.rc3 and     earlier contains a timing attack vulnerability in the     CSRF token checking that can result in signatures can be     exposed. This attack appear to be exploitable via     network connectivity to the ruby application. This     vulnerability appears to have been fixed in 1.5.5 and     2.0.0. (CVE-2018-1000119)

  - It was found that the REST interface of the pcsd service     did not properly sanitize the file name from the     /remote/put_file query. If the /etc/booth directory     exists, an authenticated attacker with write permissions     could create or overwrite arbitrary files with arbitrary     data outside of the /etc/booth directory, in the context     of the pcsd process. (CVE-2018-1079)

  - It was found that the REST interface of the pcsd service     did not properly remove the pcs debug argument from the     /run_pcs query, possibly disclosing sensitive     information. A remote attacker with a valid token could     use this flaw to elevate their privilege.
    (CVE-2018-1086)
