GHSA-4277-m35q-7c9w CVE-2023-34049 PYSEC-2026-1892

Salt preflight script could be attacker controlled

Medium PyPI

Severity: 6.7 / 10; Medium · CVSS 3.1
Exploit chance (EPSS): 0.21%; Chance of exploitation in the next 30 days. Higher than 10.78% of scored vulnerabilities.
Known exploited: No; Not in CISA's catalog
Weakness: CWE-340 Generation of Predictable Numbers or Identifiers
Fix: 3005.4; Upgrade salt to this version or later

Description

The Salt-SSH pre-flight option copies the script to the target at a predictable path, which allows an attacker to force Salt-SSH to run their script. If an attacker has access to the target VM and knows the path to the pre-flight script before it runs they can ensure Salt-SSH runs their script with the privileges of the user running Salt-SSH. Do not make the copy path on the target predictable and ensure we check return codes of the scp command if the copy fails.

Affected versions

PyPI

Package	Vulnerable	Fixed in
salt	`< 3005.4`	`3005.4`
salt	`>= 3006.0rc1, < 3006.4`	`3006.4`
salt	`< 3005.4` `>= 3006.0rc1, < 3006.4`	`3005.4` `3006.4`

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
