Detailsinfo

A vulnerability has been found in Parallels 15.1.2-47123 and classified as critical. This vulnerability affects an unknown function. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 15.1.2-47123. 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 xHCI component. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor. Was ZDI-CAN-10032.

The weakness was presented 03/23/2020. This vulnerability was named CVE-2020-8874 since 02/11/2020. The attack needs to be approached locally. Additional levels of successful authentication are necessary for exploitation. There are neither technical details nor an exploit publicly available.
