CVSS: 10.0EPSS: 97%CPEs: 43EXPL: 24CVE-2021-21972 – VMware vCenter Server Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-21972
The vSphere Client (HTML5) contains a remote code execution vulnerability in a vCenter Server plugin. A malicious actor with network access to port 443 may exploit this issue to execute commands with unrestricted privileges on the underlying operating system that hosts vCenter Server. This affects VMware vCenter Server (7.x before 7.0 U1c, 6.7 before 6.7 U3l and 6.5 before 6.5 U3n) and VMware Cloud Foundation (4.x before 4.2 and 3.x before 3.10.1.2). El VSphere Client (HTML5) contiene una vulnerabilidad de ejecución de código remota en un plugin de vCenter Server. Un actor malicioso con acceso de red al puerto 443 puede explotar este problema para ejecutar comandos con privilegios no restringidos en el sistema operativo subyacente que aloja vCenter Server. • https://www.exploit-db.com/exploits/50056 https://www.exploit-db.com/exploits/49602 https://github.com/NS-Sp4ce/CVE-2021-21972 https://github.com/horizon3ai/CVE-2021-21972 https://github.com/QmF0c3UK/CVE-2021-21972-vCenter-6.5-7.0-RCE-POC https://github.com/alt3kx/CVE-2021-21972 https://github.com/milo2012/CVE-2021-21972 https://github.com/B1anda0/CVE-2021-21972 https://github.com/TaroballzChen/CVE-2021-21972 https://github.com/GuayoyoCyber/CVE-2021-21972 https • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
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 •
