VMware Plugs Critical Flaws in Network Monitoring Product

VMware ships urgent patches to cover security defects that expose businesses to remote code execution attacks.


Virtualization technology giant VMware on Wednesday shipped urgent patches to cover security defects in the Aria Operations for Networks product, warning that the flaws expose businesses to remote code execution attacks.

VMware released an advisory documenting three critical-severity vulnerabilities haunting the network and application monitoring tool and called special attention to a command injection issue (CVE-2023-20887) that carries a CVSSv3 base 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.

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.

VMware also documented an authenticated deserialization vulnerability (CVE-2023-20888) that allows a malicious actor with network access and valid ‘member’ role credentials to launch a deserialization attack resulting in remote code execution. 

This bug carries a CVSSv3 base score of 9.1/10.

The company also patched an information disclosure flaw (CVE-2023-20889) that allows a malicious actor with network access to VMware Aria Operations for Networks  to perform command injection attacks that results in the disclosure of sensitive data.
