CVSS: 3.2EPSS: 0%CPEs: 1EXPL: 0CVE-2021-27260 – Parallels Desktop Toolgate Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-27260
This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 16.0.1-48919. 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 Toolgate component. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities 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-21-213 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2021-27242
This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 16.0.1-48919. 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 a memory corruption condition. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor. • https://kb.parallels.com/en/125013 https://www.zerodayinitiative.com/advisories/ZDI-21-209 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-35710
Parallels Remote Application Server (RAS) 18 allows remote attackers to discover an intranet IP address because submission of the login form (even with blank credentials) provides this address to the attacker's client for use as a "host" value. In other words, after an attacker's web browser sent a request to the login form, it would automatically send a second request to a RASHTML5Gateway/socket.io URI with something like "host":"192.168.###.###" in the POST data. Parallels Remote Application Server (RAS) versión 18, permite a atacantes remotos detectar una dirección IP de intranet porque el envío del formulario de inicio de sesión (inclusive con credenciales en blanco) proporciona esta dirección al cliente del atacante para usarla como valor de "host". En otras palabras, después de que el navegador web de un atacante envió una petición hacia el formulario de inicio de sesión, podría automáticamente enviar una segunda petición hacia un URI RASHTML5Gateway/socket.io con algo como "host":"192.168.###.###" en los datos POST • https://twitter.com/amadapa/status/1342407005110218753 https://www.elladodelmal.com/2020/12/blue-team-red-team-como-parallels-ras.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2020-17393
This vulnerability allows local attackers to disclose information on affected installations of Parallels Desktop 15.1.3-47255. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the prl_hypervisor kext. The issue results from the lack of proper validation of user-supplied data, which can result a pointer to be leaked after the handler is done. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel. • https://kb.parallels.com/en/125013 https://www.zerodayinitiative.com/advisories/ZDI-20-1011 • CWE-20: Improper Input Validation •
