CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-34986 – Parallels Desktop Service Time-Of-Check Time-Of-Use Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-34986
This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 16.5.0 (49183). 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 Parallels Service. By creating a symbolic link, an attacker can abuse the service to execute a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. • https://kb.parallels.com/en/125013 https://www.zerodayinitiative.com/advisories/ZDI-22-385 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
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-2021-34857
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 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 write past the end of an allocated buffer. 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-21-940 • CWE-787: Out-of-bounds Write •
