SCA: security update for github.com/jmpsec/osctrl (GHSA-rchw-322g-f7rm)

high Tenable Cloud Security Plugin ID 438043

Description

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

 - osctrl is an osquery management solution. Prior to version 0.5.0, an OS command injection vulnerability
 exists in the `osctrl-admin` environment configuration. An authenticated administrator can inject
 arbitrary shell commands via the hostname parameter when creating or editing environments. These commands
 are embedded into enrollment one-liner scripts generated using Go's `text/template` package (which does
 not perform shell escaping) and execute on every endpoint that enrolls using the compromised environment.
 An attacker with administrator access can achieve remote code execution on every endpoint that enrolls
 using the compromised environment. Commands execute as root/SYSTEM (the privilege level used for osquery
 enrollment) before osquery is installed, leaving no agent-level audit trail. This enables backdoor
 installation, credential exfiltration, and full endpoint compromise. This is fixed in osctrl `v0.5.0`. As
 a workaround, restrict osctrl administrator access to trusted personnel, review existing environment
 configurations for suspicious hostnames, and/or monitor enrollment scripts for unexpected commands.
