CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-2021-34987 – Parallels Desktop HDAudio Buffer Overflow Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-34987
This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 16.5.1 (49187). An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the HDAudio virtual device. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor. • https://kb.parallels.com/en/125013 https://www.zerodayinitiative.com/advisories/ZDI-22-386 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2020-8968
Parallels Remote Application Server (RAS) allows a local attacker to retrieve certain profile password in clear text format by uploading a previously stored cyphered file by Parallels RAS. The confidentiality, availability and integrity of the information of the user could be compromised if an attacker is able to recover the profile password. Parallels Remote Application Server (RAS) permite a un atacante local recuperar determinadas contraseñas de perfil en formato de texto sin cifrar al cargar un archivo cifrado previamente almacenado por Parallels RAS. La confidencialidad, disponibilidad e integridad de la información del usuario podría estar comprometida si un atacante es capaz de recuperar la contraseña del perfil • https://www.incibe.es/en/incibe-cert/notices/aviso/parallels-remote-application-server-credentials-management-errors • CWE-255: Credentials Management Errors •

https://notcve.org/view.php?id=CVE-2021-34868
This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 16.1.3-49160. An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Toolgate component. The issue results from the lack of proper validation of user-supplied data, which can result in an uncontrolled memory allocation. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor. • https://kb.parallels.com/125013 https://www.zerodayinitiative.com/advisories/ZDI-21-1056 • CWE-789: Memory Allocation with Excessive Size Value •
