Broadcom on Tuesday launched updates to deal with a vital security flaw impacting VMware vCenter Server that might pave the way in which for distant code execution.
The vulnerability, tracked as CVE-2024-38812 (CVSS rating: 9.8), has been described as a heap-overflow vulnerability within the DCE/RPC protocol.
“A malicious actor with community entry to vCenter Server could set off this vulnerability by sending a specifically crafted community packet probably resulting in distant code execution,” the virtualization providers supplier mentioned in a bulletin.
The shortcoming is just like two different distant code execution flaws, CVE-2024-37079 and CVE-2024-37080 (CVSS scores: 9.8), that VMware resolved in vCenter Server in June 2024.
Additionally addressed by VMware is a privilege escalation flaw within the vCenter Server (CVE-2024-38813, CVSS rating: 7.5) that might allow a malicious actor with community entry to the occasion to escalate privileges to root by sending a specifically crafted community packet.
Safety researchers zbl and srs of crew TZL have been credited with discovering and reporting the 2 flaws throughout the Matrix Cup cybersecurity competitors held in China again in June 2024. They’ve been mounted within the under variations –
- vCenter Server 8.0 (Mounted in 8.0 U3b)
- vCenter Server 7.0 (Mounted in 7.0 U3s)
- VMware Cloud Basis 5.x (Mounted in 8.0 U3b as an asynchronous patch)
- VMware Cloud Basis 4.x (Mounted in 7.0 U3s as an asynchronous patch)
Broadcom mentioned it isn’t conscious of malicious exploitation of the 2 vulnerabilities, however has urged prospects to replace their installations to the newest variations to safeguard towards potential threats.
“These vulnerabilities are reminiscence administration and corruption points which can be utilized towards VMware vCenter providers, probably permitting distant code execution,” the corporate mentioned.
The event comes because the U.S. Cybersecurity and Infrastructure Safety Company (CISA) and the Federal Bureau of Investigation (FBI) launched a joint advisory urging organizations to work in direction of eliminating cross-site scripting (XSS) flaws that risk actors may exploit to breach techniques.
“Cross-site scripting vulnerabilities come up when producers fail to correctly validate, sanitize, or escape inputs,” the federal government our bodies mentioned. “These failures permit risk actors to inject malicious scripts into net purposes, exploiting them to govern, steal, or misuse information throughout totally different contexts.”
