What it is about

PostgreSQL ist eine frei verfügbare Datenbank für unterschiedliche Betriebssysteme. Ein entfernter, authentisierter oder anonymer Angreifer kann mehrere Schwachstellen in PostgreSQL ausnutzen, um Informationen offenzulegen, beliebigen Code auszuführen und nicht näher bezeichnete Angriffe durchzuführen, was möglicherweise zu einer Ausweitung der Berechtigungen führen kann.

Under what conditions?

Over the network, but only with valid access (login required), for example with stolen credentials or as an insider.

What can happen in the worst case

An attacker could use the vulnerability to

  • Informationen offenzulegen
  • beliebigen Code auszuführen, nicht näher bezeichnete Angriffe durchzuführen
  • was möglicherweise zu einer Ausweitung der Berechtigungen führen kann

Am I affected?

Affected according to the BSI:

  • Dell NetWorker
  • Debian Linux
  • Amazon Linux 2
  • Red Hat Enterprise Linux
  • Ubuntu Linux
  • SUSE Linux
  • Oracle Linux
  • IBM QRadar SIEM
  • SUSE openSUSE
  • RESF Rocky Linux
  • Gentoo Linux
  • Dell Avamar

and 12 more

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

What helps?

Update to at least:

  • Open Source PostgreSQL 18.2
  • Open Source PostgreSQL 17.8
  • Open Source PostgreSQL 16.12
  • Open Source PostgreSQL 15.16
  • Open Source PostgreSQL 14.21
  • Splunk Splunk Enterprise 10.4.0

  • Splunk Splunk Enterprise 9.3.13
  • Dell Secure Connect Gateway 5.36.00.16

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.
