VMware has advised customers to update their vCenter Servers due to a critical flaw that could result in remote code execution. The flaw, assigned a high severity score of 9.8, allows for an out-of-bounds write vulnerability in the DCERPC protocol. It is considered a serious threat to the confidentiality, integrity, and availability of data. VMware has also released patches for end-of-life versions, highlighting the significance of the vulnerability. Another less urgent flaw was reported in VMware Cloud Foundation with a CVSS score of 4.3, which could potentially allow unauthorized access to data. It is important for organizations to patch their vCenter Servers promptly to mitigate the risk.
Key takeaways from the meeting notes are as follows:
1. VMware urges customers to update their VMware vCenter Servers due to a critical flaw, CVE-2023-34048, which has a severity score of 9.8. This flaw could potentially lead to remote code execution.
2. The vCenter Server flaw allows an attacker with network access to trigger an out-of-bounds write vulnerability in the implementation of the DCERPC protocol.
3. The impact of the flaw is severe as it affects the confidentiality, integrity, and availability of the environment. Successful exploitation of this vulnerability gives complete access to the environment and enables further exploitation.
4. VMware has taken the unusual step of offering patches for end-of-life (EOL) versions that are affected by this vulnerability, emphasizing its critical nature.
5. Additionally, another flaw, CVE-2023-34056, has been reported in VMware Cloud Foundation with a lower CVSS score of 4.3. This vulnerability could allow unauthorized access to data.
6. It is important for organizations using vCenter Server to have a current inventory of its usage and a plan to patch. Mitigation options appear limited, but network access control and monitoring can help detect lateral movement once a threat actor gains access.
