What it is about

PostgreSQL ist eine frei verfügbare Datenbank für unterschiedliche Betriebssysteme. Ein Angreifer kann mehrere Schwachstellen in PostgreSQL ausnutzen, um beliebigen Programmcode auszuführen, SQL-Injection-Angriffe durchzuführen, Sicherheitsmaßnahmen zu umgehen, Daten offenzulegen oder zu manipulieren oder Denial-of-Service-Zustände herbeizuführen.

Under what conditions?

The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.

What can happen in the worst case

An attacker could use the vulnerability to

  • beliebigen Programmcode auszuführen
  • SQL-Injection-Angriffe durchzuführen
  • Sicherheitsmaßnahmen zu umgehen
  • Daten offenzulegen oder zu manipulieren oder Denial-of-Service-Zustände herbeizuführen

Am I affected?

Affected according to the BSI:

  • IBM VIOS 4.1
  • Debian Linux
  • Amazon Linux 2
  • Red Hat Enterprise Linux
  • IBM QRadar SIEM
  • F5 BIG-IP
  • RESF Rocky Linux
  • SUSE Linux
  • SUSE openSUSE
  • Ubuntu Linux
  • Oracle Linux
  • Open Source PostgreSQL <18.6

and 5 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 18.6
  • Open Source PostgreSQL 17.11
  • Open Source PostgreSQL 16.15
  • Open Source PostgreSQL 15.19
  • Open Source PostgreSQL 14.24
  • Open Source PostgreSQL 19 Beta 3

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.
