HIGH8.8EPSS 0.61%

Incorrect Permission Assignment for Critical Resource in Singularity

Published: 12/20/2021Modified: 11/8/2023

Description

An issue was discovered in Singularity 3.1.0 to 3.2.0-rc2, a malicious user with local/network access to the host system (e.g. ssh) could exploit this vulnerability due to insecure permissions allowing a user to edit files within `/run/singularity/instances/sing/<user>/<instance>`. The manipulation of those files can change the behavior of the starter-suid program when instances are joined resulting in potential privilege escalation on the host.
