VMware Patches Major Security Flaws in Network Monitoring Product

VWware patches critical flaws that allow hackers to bypass SSH authentication and gain access to the Aria Operations for Networks command line interface.


Virtualization technology giant VMware on Tuesday shipped a major security update to correct at least two critical vulnerabilities in its Aria Operations for Networks product line.

In a critical-severity advisory, VMware said the flaws could be exploited by malicious hackers to bypass SSH authentication and gain access to the Aria Operations for Networks command line interface.

VMware tagged the network authentication bypass issue as CVE-2023-34039 and applied a CVSS severity score of 9.8 out of 10.

“Aria Operations for Networks contains an authentication bypass vulnerability due to a lack of unique cryptographic key generation. VMware has evaluated the severity of this issue to be in the critical severity range with a maximum CVSSv3 base score of 9.8,” the company said.

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

The company said the Aria Operations for Networks collectors are impacted by  the vulnerability but advised customers that upgrading the platform appliance will  remediate the issue. 

VMware also shipped a patch for a second bug  — CVE-2023-20890 —  that allows an authenticated malicious actor with administrative access to VMware Aria Operations for Networks to write files to arbitrary locations.
