Red Hat Satellite 6.16 for RHEL 8: Improper Neutralization of Special Elements used in an OS Command

CVE-2026-12541 is a high-severity improper neutralization of special elements used in an OS command vulnerability in Red Hat Satellite 6.16 for RHEL 8 from Red Hat, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited with local access to the system by an attacker with administrator privileges, without any action from a user. There is no confirmed exploitation so far. EPSS estimates a 1.24% chance of exploitation within 30 days, higher than 70% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Satellite to 6.16.4 or 6.17.12 or 6.19.5 or 6.18.10, whichever matches your release line, or a later version.
  2. Read the advisory on access.redhat.com for workarounds and exact fixed builds.

Official description

A flaw was found in Foreman. OS command injection vulnerabilities exist in the foreman-rake db:dump and db:import_dump tasks. The application fails to properly sanitize user-supplied input in the destination parameter (during backups) and the file parameter (during imports) before passing them to a Ruby system() call for execution. An attacker with permissions to execute foreman-rake (e.g., via a restricted sudo configuration) can append malicious shell commands to the provided file paths.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
