What it is about

Red Hat Satellite dient als zentrale Stelle für das Management, die Verteilung von Updates in Netzwerken mit Red Hat Enterprise Linux Systemen. Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein entfernter, anonymer oder authentisierter Angreifer kann mehrere Schwachstellen in Red Hat Satellite und Red Hat Enterprise Linux ausnutzen, um einen Denial of Service Angriff durchzuführen und um beliebige SQL-Befehle einzuschleusen.

Under what conditions?

Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.

What can happen in the worst case

An attacker could use the vulnerability to

  • einen Denial of Service Angriff durchzuführen
  • beliebige SQL-Befehle einzuschleusen

Am I affected?

Affected according to the BSI:

  • Red Hat Enterprise Linux
  • Ubuntu Linux
  • SUSE Linux
  • Red Hat Satellite <6.17
  • Red Hat Satellite <6.16
  • Red Hat Satellite <6.15
  • Red Hat Enterprise Linux 8
  • Red Hat Enterprise Linux 9

The installed version is usually shown under “Help → About” or in the device’s admin interface.

What helps?

Update to at least:

  • Red Hat Satellite 6.17
  • Red Hat Satellite 6.16
  • Red Hat Satellite 6.15

Is the vulnerability already being exploited?

None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.

Information and sources

CVE: CVE-2025-10990, CVE-2025-57052, CVE-2025-57833
