CVE-2024-29849 Analysis
A critical VBEM security bug (CVE-2024-29849) has recently hit the headlines. The vendor released an advisory, notifying customers about a novel vulnerability that enables threat actors to overcome authentication protection upon its successful exploitation.
The vendor also revealed three additional security bugs affecting the same product, including CVE-2024-29850 which could lead to account compromise via NTLM relay, CVE-2024-29851, enabling a user with elevated privileges to pilfer NTLM hashes of a VBEM service account unless it’s configured to run as the default Local System account, and CVE-2024-29852, permitting an authorized user to retrieve backup session logs.
Earlier, adversaries weaponized vulnerabilities in Veeam products against organizations in the U.S. and Latin America, particularly, CVE-2023-27532, a security bug in Veeam Backup & Replication software.
Since a PoC for CVE-2024-29849 has surfaced online, it’s imperative that administrators promptly install the most recent security patches. To remediate the risks of weaponized attacks, the vendor has instantly addressed the patches in the VBEM version 12.1.2.172. For those unable to patch to the above-referenced VBEM version, defenders recommend limiting access to the VBEM web interface to trusted IP addresses, enabling MFA, and continuously keeping track of access logs for suspicious activity as temporary CVE-2024-29849 mitigation measures.
Since the risks of attacks weaponizing known vulnerabilities in popular software products leveraged by global enterprises are continuously escalating, defenders are searching for ways to take proactive threat detection to the next level.
