Summaryinfo

A vulnerability labeled as very critical has been found in PassMark BurnInTest, OSForensics and PerformanceTest. This issue affects some unknown processing of the file DirectIo64.sys of the component Driver. The manipulation results in hard-coded credentials. This vulnerability is known as CVE-2026-80114. Attacking locally is a requirement. No exploit is available.

Detailsinfo

A vulnerability classified as very critical has been found in PassMark BurnInTest, OSForensics and PerformanceTest (the affected version unknown). Affected is an unknown part of the file DirectIo64.sys of the component Driver. The manipulation with an unknown input leads to a hard-coded credentials vulnerability. CWE is classifying the issue as CWE-798. The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a hard-coded credentials vulnerability in DirectIo64.sys that allows local attackers to perform arbitrary physical memory writes by extracting an 8-byte key embedded as a hardcoded literal in the distributed binary and computing valid MD5 authentication tags for arbitrary IOCTL write requests. Attackers can additionally bypass a secondary validation gate by using the driver's own bit-clear IOCTL to clear a single bit in the gating instruction's displacement byte, causing all subsequent write requests to skip MAC verification, size checks, and Vendor ID checks entirely.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-80114 since 08/25/2026. The exploitability is told to be easy. Local access is required to approach this attack. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 09/04/2026). This vulnerability is assigned to T1110.001 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
