CVSS: 8.8EPSS: 93%CPEs: 233EXPL: 3CVE-2021-21974 – VMware ESXi SLP Heap-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-21974
OpenSLP as used in ESXi (7.0 before ESXi70U1c-17325551, 6.7 before ESXi670-202102401-SG, 6.5 before ESXi650-202102101-SG) has a heap-overflow vulnerability. A malicious actor residing within the same network segment as ESXi who has access to port 427 may be able to trigger the heap-overflow issue in OpenSLP service resulting in remote code execution. OpenSLP como es usado en ESXi (versiones 7.0 anteriores a ESXi70U1c-17325551, versiones 6.7 anteriores a ESXi670-202102401-SG, versiones 6.5 anteriores a ESXi650-202102101-SG), presenta una vulnerabilidad de desbordamiento de la pila. Un actor malicioso que reside dentro del mismo segmento de red que ESXi y que presenta acceso al puerto 427 puede desencadenar el problema de desbordamiento de la pila en el servicio OpenSLP, resultando en una ejecución de código remota This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of VMware ESXi. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of SLP messages. • https://github.com/Shadow0ps/CVE-2021-21974 https://github.com/n2x4/Feb2023-CVE-2021-21974-OSINT http://packetstormsecurity.com/files/162957/VMware-ESXi-OpenSLP-Heap-Overflow.html https://www.vmware.com/security/advisories/VMSA-2021-0002.html https://www.zerodayinitiative.com/advisories/ZDI-21-250 • CWE-787: Out-of-bounds Write •

VMware ESXi (7.0 before ESXi70U1b-17168206, 6.7 before ESXi670-202011101-SG, 6.5 before ESXi650-202011301-SG), Workstation (15.x before 15.5.7), Fusion (11.x before 11.5.7) contain a use-after-free vulnerability in the XHCI USB controller. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. VMware ESXi (versiones 7.0 anteriores a ESXi70U1b-17168206, versiones 6.7 anteriores a ESXi670-202011101-SG, versiones 6.5 anteriores a ESXi650-202011301-SG), Workstation (versiones 15.x anteriores a 15.5.7), Fusion (versiones 11.x anteriores a 11.5.7), contienen una vulnerabilidad de uso de la memoria previamente liberada en el controlador USB XHCI. Un actor malicioso con privilegios administrativos locales en una máquina virtual puede explotar este problema para ejecutar código como el proceso VMX de la máquina virtual que se ejecuta en el host • https://www.vmware.com/security/advisories/VMSA-2020-0026.html • CWE-416: Use After Free •

In VMware ESXi (6.7 before ESXi670-201908101-SG, 6.5 before ESXi650-202007101-SG), Workstation (15.x before 15.1.0), Fusion (11.x before 11.1.0), the VMCI host drivers used by VMware hypervisors contain a memory leak vulnerability. A malicious actor with access to a virtual machine may be able to trigger a memory leak issue resulting in memory resource exhaustion on the hypervisor if the attack is sustained for extended periods of time. En VMware ESXi (versiones 6.7 anteriores a ESXi670-201908101-SG, versiones 6.5 anteriores a ESXi650-202007101-SG), Workstation (versiones 15.x anteriores a 15.1.0), Fusion (versiones 11.x anteriores a 11.1.0), los controladores del host VMCI utilizados por los hipervisores de VMware contienen una vulnerabilidad de filtrado de memoria. Un actor malicioso con acceso a una máquina virtual puede desencadenar un problema de filtrado de memoria que resulte en el agotamiento de los recursos de memoria en el hipervisor si el ataque se mantiene durante períodos prolongados • https://www.vmware.com/security/advisories/VMSA-2020-0023.html • CWE-401: Missing Release of Memory after Effective Lifetime •
