IBM DB2: Mehrere Schwachstellen
WID-SEC-2026-3308 · first 11.09.2026 · updated 26.10.2026 · CVSS 9,8
What it is about
IBM DB2 ist ein relationales Datenbanksystem (RDBS) von IBM. Ein Angreifer kann mehrere Schwachstellen in IBM DB2 ausnutzen, um beliebigen Programmcode auszuführen, beliebige Dateien zu schreiben, Daten zu manipulieren, sensible Informationen offenzulegen oder Denial-of-Service-Zustände zu verursachen.
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
- beliebige Dateien zu schreiben
- Daten zu manipulieren
- sensible Informationen offenzulegen oder Denial-of-Service-Zustände zu verursachen
Am I affected?
Affected according to the BSI:
- IBM License Metric Tool
- IBM DB2 V11.5 <APAR DT472908
- IBM DB2 V12.1 <APAR DT472908
- IBM DB2 V11.5 <APAR DT470425
