VMware patches critical vulnerability in vCenter Server (CVE-2023-34048)

VMware has fixed a critical out-of-bounds write vulnerability and a moderate-severity information disclosure flaw in vCenter Server, its popular server management software.

CVE-2023-34048 allows an attacker with network access to a vulnerable vCenter Server virtual appliance to trigger an out-of-bounds write that can lead to remote code execution.

A second vulnerability in the VMware vCenter Server has been reported by Oleg Moshkov of Deiteriy Lab OÜ. It is a partial information disclosure vulnerability that could allow an attacker with non-administrative privileges to access unauthorized data.

“Due to the critical severity of this vulnerability and lack of workaround VMware has made a patch generally available for vCenter Server 6.7U3, 6.5U3, and VCF 3.x. For the same reasons, VMware has made additional patches available for vCenter Server 8.0U1,” the company said.

Asynchronous vCenter Server patches for VCF 5.x and 4.x deployments are also available.

In June, a critical pre-authentication command injection vulnerability in VMware Aria Operations for Network was observed being exploited in the wild.
