Virtualization technology giant VMware on Tuesday pushed out a major security fix to cover a critical vulnerability in its enterprise-facing Carbon Black App Control product.
A critical-severity advisory from VMware tracks the vulnerability as CVE-2023-20858 and warns that hackers can launch injection exploits to gain full access to the underlying server operating system.
“A malicious actor with privileged access to the App Control administration console may be able to use specially crafted input allowing access to the underlying server operating system,” VMware warned.
The vulnerability, which carries a CVSS severity score of 9.1 out of 10, affects App Control versions 8.7.x, 8.8.x and 8.9.x running on Microsoft’s Windows operating system.
The company said the issue was privately reported by Jari Jääskelä, a security researcher active on the HackerOne bug bounty platform.
VMware Carbon Black App Control is a security product used by enterprise defenders to ensure that only trusted and approved software is allowed to execute on critical systems and endpoints.
VMware also issued an important-severity advisory to warn of a privilege escalation and information disclosure flaw in its vRealize Orchestrator product.
“A malicious actor, with non-administrative access to vRealize Orchestrator, may be able to use specially crafted input to bypass XML parsing restrictions leading to access to sensitive information or possible escalation of privileges,” the company said.
