Veeam Backup & Replication Remote Code Execution Vulnerability
The Veeam Distribution Service in the Backup & Replication application allows unauthenticated users to access internal API functions. A remote attacker can send input to the internal API which may lead to uploading and executing of malicious code.
A remote attacker, with a low-privilege account, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. CISA has confirmed use of this vulnerability in known ransomware campaigns — treat as high priority for remediation. Federal agencies are required to remediate by 2023-01-03 under CISA BOD 22-01.
This is a Path Traversal (CWE-22) vulnerability in Veeam Backup & Replication. Improper limitation of path names in Veeam Backup & Replication 9.5U3, 9.5U4,10.x, and 11.x allows remote authenticated users access to internal API functions that allows attackers to upload and execute arbitrary code. Exploitation requires remote network access, low attack complexity, a low-privilege authenticated account, and no user interaction required.
Probably yes if any of these apply:
CISA confirms this CVE has been used in known ransomware campaigns. Added to the KEV catalog on 2022-12-13; federal agencies required to remediate by 2023-01-03.
