Insufficient audit logging in VMware ESX and related Broadcom virtualization platforms allows a malicious administrator to perform certain privileged operations without generating corresponding log entries. Affected products span the VMware ecosystem including Cloud Foundation, vSphere Foundation, ESX, and Telco Cloud Platform. No public exploit code exists and the vulnerability is not listed in CISA KEV, but the insider-threat and post-compromise forensic evasion implications are meaningful for organizations relying on audit logs for compliance and incident response.
Information disclosure and host-process Denial-of-Service affects VMware ESX, Workstation, and Fusion via an out-of-bounds read (CWE-125) reachable by an actor holding VM deployment privileges. On ESX the flaw can crash or leak memory from the host VMX process (a guest-to-host scope crossing), while on Workstation and Fusion the impact is limited to information disclosure. Reported by VMware/Broadcom with no public exploit identified at time of analysis and no CISA KEV listing.
Guest-to-host escape in VMware ESX (and the ESX component of Cloud Foundation, vSphere Foundation, and Telco Cloud Platform) lets an attacker with administrative privileges inside a virtual machine execute code on the underlying hypervisor host via an out-of-bounds write in the VMXNET3 virtual network adapter. Only VMs configured with the VMXNET3 adapter are affected; other virtual NIC types are not. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the vendor-issued Broadcom/VMware advisory and the CVSS 9.3 score reflect a critical host-compromise impact.
Authentication bypass in VMware vCenter's Directory Service (vmdir) lets an attacker with network reachability to vCenter defeat the authentication algorithm and obtain unauthorized access without valid credentials. Because vCenter is the central management plane for vSphere environments, this exposes control over the entire virtual estate; the flaw is remotely exploitable with no privileges or user interaction (CVSS 9.8). At time of analysis there is no public exploit identified and it is not listed in CISA KEV, but the reporting vendor (VMware/Broadcom) rates it critical.
Remote code execution in VMware vCenter Server (and bundled distributions including Cloud Foundation, vSphere Foundation, Telco Cloud Infrastructure, and Telco Cloud Platform) arises from a directory traversal flaw in the Syslog server component, enabling any actor with network reach to vCenter to run arbitrary code. The CVSS 9.8 vector indicates unauthenticated, low-complexity network exploitation with full confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and it is not yet listed in CISA KEV, but the vCenter management plane's central role makes this a top-priority patch.
