2) UNIX symbolic link following
EUVDB-ID: #VU26515
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-18466
CWE-ID:
CWE-61 - UNIX Symbolic Link (Symlink) Following
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue in libpod (podman) in the host context during a copy operation from the container to the
host, because an undesired glob operation occurs. An attacker could
create a container image containing particular symlinks that, when
copied by a victim user to the host filesystem, may overwrite existing
files with others from the host.
Successful exploitation of this vulnerability may result in privilege escalation on the host operating system.
