CVSS: 9.3EPSS: 0%CPEs: 4EXPL: 0CVE-2020-15229 – Path traversal and files overwrite with unsquashfs
https://notcve.org/view.php?id=CVE-2020-15229
Singularity (an open source container platform) from version 3.1.1 through 3.6.3 has a vulnerability. Due to insecure handling of path traversal and the lack of path sanitization within `unsquashfs`, it is possible to overwrite/create any files on the host filesystem during the extraction with a crafted squashfs filesystem. The extraction occurs automatically for unprivileged (either installation or with `allow setuid = no`) run of Singularity when a user attempt to run an image which is a local SIF image or a single file containing a squashfs filesystem and is coming from remote sources `library://` or `shub://`. Image build is also impacted in a more serious way as it can be used by a root user, allowing an attacker to overwrite/create files leading to a system compromise, so far bootstrap methods `library`, `shub` and `localimage` are triggering the squashfs extraction. This issue is addressed in Singularity 3.6.4. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00070.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00009.html https://github.com/hpcng/singularity/blob/v3.6.4/CHANGELOG.md#security-related-fixes https://github.com/hpcng/singularity/commit/eba3dea260b117198fdb6faf41f2482ab2f8d53e https://github.com/hpcng/singularity/pull/5611 https://github.com/hpcng/singularity/security/advisories/GHSA-7gcp-w6ww-2xv9 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
