VMware vCenter Server RCE Vulnerability Actively Exploited in Assaults

Broadcom has issued an pressing warning that two important vulnerabilities in VMware vCenter Server at the moment are being actively exploited within the wild.

The extra extreme of the 2 flaws is a distant code execution (RCE) vulnerability tracked as CVE-2024-38812, which carries a most CVSSv3 rating of 9.8.

CVE-2024-38812 stems from a heap overflow weak point within the vCenter Server’s implementation of the DCE/RPC protocol. An attacker with community entry can set off this vulnerability by sending a specifically crafted packet, probably resulting in distant code execution and full system compromise.

The second vulnerability, CVE-2024-38813, permits attackers to escalate privileges to root by sending maliciously crafted community packets. It has a CVSSv3 rating of seven.5.

Each vulnerabilities have been initially reported by researchers zbl & srs of crew TZL throughout China’s 2024 Matrix Cup hacking contest. They have an effect on VMware vCenter Server variations 7.0 and eight.0 and VMware Cloud Basis variations 4.x and 5.x.
