Detailsinfo

A vulnerability classified as critical was found in PassMark BurnInTest, OSForensics and PerformanceTest (affected version unknown). Affected by this vulnerability is an unknown functionality in the library DirectIo32.sys of the component Request Handler. The manipulation as part of a Request leads to a buffer overflow vulnerability. The CWE definition for the vulnerability is CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered in PassMark BurnInTest through 9.1, OSForensics through 7.1, and PerformanceTest through 10. The driver's IOCTL request handler attempts to copy the input buffer onto the stack without checking its size and can cause a buffer overflow. This could lead to arbitrary Ring-0 code execution and escalation of privileges. This affects DirectIo32.sys and DirectIo64.sys.

The weakness was released 08/07/2020. This vulnerability is known as CVE-2020-15479 since 07/01/2020. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. Technical details of the vulnerability are known, but there is no available exploit.
