CVE-2021-31418 – Parallels Desktop Toolgate Uninitialized Memory Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-31418
This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 15.1.4-47270. 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 initialization of memory prior to accessing it. 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-21-429 • CWE-908: Use of Uninitialized Resource •
CVE-2021-31430 – Parallels Desktop IDE Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-31430
This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 15.1.5-47309. 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 IDE virtual device. 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-21-438 • CWE-125: Out-of-bounds Read •
CVE-2020-17401 – Parallels Desktop VGA Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2020-17401
This vulnerability allows local attackers to disclose sensitive informations on affected installations of Parallels Desktop 15.1.4. 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 VGA virtual device. 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 array. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute code in the context of the hypervisor. • https://kb.parallels.com/en/125013 https://www.zerodayinitiative.com/advisories/ZDI-20-1019 • CWE-129: Improper Validation of Array Index •
CVE-2020-17392 – Parallels Desktop prl_hypervisor Untrusted Pointer Dereference Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-17392
This vulnerability allows local attackers to escalate privileges 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 handler for HOST_IOCTL_SET_KERNEL_SYMBOLS in the prl_hypervisor kext. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. • https://kb.parallels.com/en/125013 https://www.zerodayinitiative.com/advisories/ZDI-20-1010 • CWE-822: Untrusted Pointer Dereference •
CVE-2020-17393 – Parallels Desktop prl_hypervisor Improper Input Validation Information Disclosure Vulnerability
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 •
