What it is about

Adobe Connect ist eine Software zur Erstellung von Informationen, Präsentationen, Online-Schulungsunterlagen, Webkonferenzen, Lernmodulen und für Benutzer-Desktop-Sharing. Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in Adobe Connect ausnutzen, um einen SQL-Injection Angriff durchzuführen, um einen Cross-Site Scripting Angriff durchzuführen, um beliebigen Programmcode auszuführen, um Informationen offenzulegen und um Sicherheitsvorkehrungen zu umgehen.

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

  • einen SQL-Injection Angriff durchzuführen
  • einen Cross-Site Scripting Angriff durchzuführen
  • beliebigen Programmcode auszuführen
  • Informationen offenzulegen
  • Sicherheitsvorkehrungen zu umgehen

Am I affected?

Affected according to the BSI:

  • Adobe Connect <12.12

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

What helps?

Update to at least:

  • Adobe Connect 12.12

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.
