What it is about
Commvault Backup & Recovery ist eine Plattform, die eine vollständige Sicherung und Wiederherstellung aller Workloads ermöglicht. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Commvault Backup & Recovery ausnutzen, um Sicherheitsvorkehrungen zu umgehen, beliebigen Code auszuführen und serverseitige Request-Forgery-Angriffe durchzuführen
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- Sicherheitsvorkehrungen zu umgehen
- beliebigen Code auszuführen
- serverseitige Request-Forgery-Angriffe durchzuführen

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.
