CVE-2015-2291 is a high-severity vulnerability found in the Intel Ethernet diagnostics driver, specifically in the IQVW32.sys and IQVW64.sys files prior to version 1.3.1.0. This vulnerability allows local users to cause a denial of service or even execute arbitrary code with kernel privileges through crafted IOCTL calls. The CVSS score for this vulnerability is 7.8, indicating a high level of risk due to the potential for significant impact on system integrity and availability.
The real-world implications of this vulnerability are notable. Attackers with local access can exploit this flaw to gain kernel-level privileges, leading to potential system crashes or unauthorized actions. As attackers may leverage this vulnerability for malicious purposes, organizations should prioritize patching immediately to mitigate risks.
Currently, there is a known exploit associated with this vulnerability, and it has been included in the Known Exploited Vulnerabilities (KEV) catalog. Organizations should be aware that this vulnerability has been actively targeted, thus increasing the urgency for remediation efforts.
Intel has provided a patch to address this vulnerability. Organizations are advised to implement the patch as soon as possible to prevent potential exploitation and maintain system integrity.
Vulnerability Details
CVE-2015-2291 affects the Intel Ethernet diagnostics driver for Windows, specifically versions of IQVW32.sys and IQVW64.sys before 1.3.1.0. The official CVE description indicates that this vulnerability allows local users to execute arbitrary code or cause a denial of service through specific IOCTL calls. The vulnerability is classified under CWE-20, indicating improper input validation.
With a CVSS score of 7.8, this vulnerability is rated as high severity, reflecting the significant potential for impact on confidentiality, integrity, and availability. The vulnerability was published on August 9, 2017, and remains relevant due to its inclusion in active exploitation catalogs.
Technical Analysis
The root cause of CVE-2015-2291 stems from the failure in input validation within the Intel Ethernet diagnostics driver. This flaw allows attackers to send crafted IOCTL calls that can compromise the system’s kernel. The attack vector is local, indicating that the attacker needs physical or remote desktop access to exploit the vulnerability.
The attack complexity is rated as low, meaning that exploitation can be performed without significant effort. The privileges required for exploitation are low, meaning unprivileged users can potentially carry out attacks. User interaction is not required for exploitation, making this vulnerability particularly dangerous.
The impacts of exploitation include high confidentiality, integrity, and availability impacts, as the attacker can execute arbitrary code with kernel privileges, leading to complete control over the affected system.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access and control over critical systems, which could lead to data breaches, system outages, or further exploitation of network resources. The blast radius of this vulnerability is significant, as it impacts local users with access to the affected systems.
Given the high CVSS score of 7.8 and the existence of known exploitation, organizations must assess their exposure and prioritize remediation efforts. The urgency for addressing this vulnerability is critical, especially for organizations that utilize Intel Ethernet diagnostics drivers in their operations.
