A path traversal vulnerability in KubeVirt versions up to 0.56 (and 0.55.1) on all platforms allows a user able to configure the kubevirt to read arbitrary files on the host filesystem which are publicly readable or which are readable for UID 107 or GID 107. /proc/self/<> is not accessible.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A path traversal vulnerability in KubeVirt versions up to 0.56 (and 0.55.1) on all platforms allows a user
    able to configure the kubevirt to read arbitrary files on the host filesystem which are publicly readable
    or which are readable for UID 107 or GID 107. /proc/self/<> is not accessible. (CVE-2022-1798)

The version of kubevirt installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-1798 advisory.

  - A path traversal vulnerability in KubeVirt versions up to 0.56 (and 0.55.1) on all platforms allows a user     able to configure the kubevirt to read arbitrary files on the host filesystem which are publicly readable     or which are readable for UID 107 or GID 107. /proc/self/<> is not accessible. (CVE-2022-1798)

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

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3333-1 advisory.

    The kubevirt stack was updated to version 0.54.0
