CVE-2025-52347 is a high-severity vulnerability affecting the component DirectIo64.sys in PassMark BurnInTest v11.0 Build 1011, OSForensics v11.1 Build 1007, and PerformanceTest v11.1 Build 1004. This vulnerability allows attackers to access kernel memory and escalate privileges via a crafted IOCTL 0x8011E044 call. With a CVSS score of 7.8, this vulnerability poses a significant risk to organizations, necessitating immediate attention.
Risk to organizations includes potential unauthorized access to sensitive system resources, which can lead to further exploitation or data breaches. Given the nature of this vulnerability, organizations should prioritize patching immediately to prevent any exploitation.
Currently, CVE-2025-52347 is marked as 'Awaiting Analysis', which means that detailed exploitation status and public exploit information are not yet available. However, the potential for exploitation underscores the urgency for defenders to assess their systems and apply necessary mitigations.
Organizations utilizing the affected products should not only patch their systems but also review their security configurations and monitoring capabilities to detect any unusual activities resulting from this vulnerability.
Vulnerability Details
The vulnerability allows attackers to execute a crafted IOCTL call, which can lead to unauthorized access to kernel memory. This could enable privilege escalation, allowing attackers to execute arbitrary code with elevated permissions.
The CVSS score of 7.8 indicates a high-severity vulnerability, characterized by a low attack complexity and low privileges required for exploitation. The potential impacts on confidentiality, integrity, and availability are all rated as high, highlighting the serious risk posed by this vulnerability.
Technical Analysis
The root cause of CVE-2025-52347 stems from improper handling of IOCTL calls within the DirectIo64.sys component. Attackers can exploit this vulnerability locally due to its low attack complexity, meaning that a malicious actor with local access to the system can potentially leverage this issue without needing any user interaction.
The attack vector is local, meaning that an attacker needs to have physical or remote access to the machine to exploit the vulnerability. The privileges required are low, allowing a basic user to execute the exploit without needing elevated permissions. Since user interaction is not required, the attack can be automated.
The impacts of a successful exploitation of this vulnerability include significant risks to confidentiality, integrity, and availability of system resources. Therefore, the potential for a widespread impact on organizations that utilize the affected software is considerable.
Risk & Impact Analysis
Organizations running the affected versions of PassMark BurnInTest, OSForensics, or PerformanceTest face substantial risks. Exploitation of this vulnerability could lead to unauthorized access to sensitive kernel memory, allowing attackers to execute arbitrary code and potentially take full control of the system.
The blast radius includes all systems running the vulnerable versions, which could result in data breaches or further attacks against the organization. This vulnerability represents a critical component of the organization's risk landscape and should be addressed immediately.
Given the CVSS score and potential for exploitation, organizations should address this vulnerability in their priority patch cycle. Regular reviews of software components and their vulnerabilities should be a part of the organization's security practices.
