What it is about

Cisco License On-Prem (fürher Smart Software Manager On-Prem) ist eine lokale Lizenzverwaltungslösung, die mit dem Cisco Smart Software Manager kommuniziert, um Lizenzen für Cisco-Produkte im eigenen Netzwerk zu verwalten. Ein Angreifer kann mehrere Schwachstellen in Cisco License On-Prem ausnutzen, um Sicherheitsvorkehrungen zu umgehen, um seine Privilegien zu erhöhen, um einen Denial of Service Angriff durchzuführen, um Informationen offenzulegen, um einen SQL-Injection Angriff durchzuführen und um beliebigen Programmcode auszuführen.

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

  • Sicherheitsvorkehrungen zu umgehen
  • seine Privilegien zu erhöhen
  • einen Denial of Service Angriff durchzuführen
  • Informationen offenzulegen
  • einen SQL-Injection Angriff durchzuführen
  • beliebigen Programmcode auszuführen

Am I affected?

Affected according to the BSI:

  • Cisco License On-Prem <10-202609

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

What helps?

Update to at least:

  • Cisco License On-Prem 10-202609

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.
