Questions about CVE-2022-26500
What does this mean?
The Veeam Distribution Service does not properly limit path names, which lets remote users reach internal API functions. The vendor-described impact is remote code execution, which could give an attacker control of the target system.Source: veeam.com
Am I affected, and how do I check?
The description names Veeam Backup & Replication 9.5U3, 9.5U4, 10.x, and 11.x. The exposed setup is a host where the Veeam Distribution Service is installed and running, which listens on TCP 9380 by default. To check, confirm whether that service is present and running on the server.Source: veeam.com
What should I do about it?
Apply the vendor patch for your Veeam Backup & Replication version. The fixed version numbers are not listed in the checked facts, so confirm them in Veeam's advisory.Source: veeam.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-12-13, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
What if there's no patch?
Stop and disable the Veeam Distribution Service until a patch is installed. The checked facts give this as the workaround.Source: veeam.com
