VMware Confirms Live Exploits Hitting Just-Patched Security Flaw

VMware updates a critical-level bulletin: “VMware has confirmed that exploitation of CVE-2023-20887 has occurred in the wild.”


Less than two weeks after shipping urgent patches to cover security defects in its Aria Operations for Networks product, VMware says hackers have started launching exploits in the wild.

The virtualization technology giant on Tuesday updated a critical-level bulletin with a blunt warning to businesses running the network monitoring software: “VMware has confirmed that exploitation of CVE-2023-20887 has occurred in the wild.”

The live exploits, first flagged by GreyNoise, target the CVE-2023-20887 command injection vulnerability that carries a CVSS severity score of 9.8/10.

“A malicious actor with network access to VMware Aria Operations for Networks may be able to perform a command injection attack resulting in remote code execution,” VMware said in an advisory released earlier this month.

In all, VMware documented three critical-severity vulnerabilities that expose businesses to remote code execution and information disclosure attacks. 

The VMware Aria Operations for Networks, formerly vRealize Network Insight, is used by enterprises to monitor, discover and analyze networks and applications to build secure network infrastructure across clouds.
