CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-34854 – Parallels Desktop Toolgate Uncontrolled Memory Allocation Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-34854
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-21-937 • CWE-770: Allocation of Resources Without Limits or Throttling CWE-789: Memory Allocation with Excessive Size Value •

https://notcve.org/view.php?id=CVE-2021-34855
This vulnerability allows local attackers to disclose sensitive information 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 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/125013 https://www.zerodayinitiative.com/advisories/ZDI-21-939 • CWE-908: Use of Uninitialized Resource •

https://notcve.org/view.php?id=CVE-2021-31429
This vulnerability allows local attackers to escalate privileges 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 the length of user-supplied data prior to copying it to a fixed-length heap-based 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-21-437 • CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2021-31427
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 low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Open Tools Gate component. The issue results from the lack of proper locking when performing operations on an object. 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-21-435 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-667: Improper Locking •

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.
