Document Title: =============== Intel(R) HD Graphics 10 - Unquoted Path Privilege Escalation References (Source): ==================== https://www.vulnerability-lab.com/get_content.php?id=1981 Release Date: ============= 2016-11-02 Vulnerability Laboratory ID (VL-ID): ==================================== 1981 Common Vulnerability Scoring System: ==================================== 4.3 Product & Service Introduction: =============================== Intel Corp. designs, manufactures and sells computer components and related products. The company also engages in the designing and manufacturing of computing and communication components, such as microprocessors, chipsets, motherboards, and wireless and wired connectivity products. It develops advanced integrated digital technology products, primarily integrated circuits, for industries such as computing and communications. (Copy of the Vendor Homepage: http://www.intel.fr/ ) Abstract Advisory Information: ============================== An independent vulnerability laboratory researcher discovered an unquoted service path privilege escalation vulnerability in the Intel(R) HD Graphics v10.x software. Vulnerability Disclosure Timeline: ================================== 2016-11-02: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Intel Atom Product: Intel(R) HD Graphics - Software 10.18.10.4358 Exploitation Technique: ======================= Local Severity Level: =============== Medium Technical Details & Description: ================================ The application suffers from a search path issue unquoted impact on Intel(R) HD Graphics. This could potentially allow authorized but unprivileged local user accounts with system access to unauthorized execute arbitrary code with system privileges of the affected software process. The security risk of the software vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 4.4. Exploitation of the software vulnerability requires a low privilege system user account with restricted access and without user interaction. Successful exploitation of the vulnerability results in system process compromise and further manipulation or exploitation to compromise the local computer operating system. Proof of Concept (PoC): ======================= The issue can be exploited by local attackers with restricted system user account or network access and without user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue. --- PoC Privileges Session Logs --- C:Program FilesIntelTXE ComponentsDAL>sc qc jhi_service [SC] QueryServiceConfig réussite(s) SERVICE_NAME: jhi_service TYPE : 10 WIN32_OWN_PROCESS START_TYPE : 2 AUTO_START (DELAYED) ERROR_CONTROL : 0 IGNORE BINARY_PATH_NAME : "C:Program FilesIntelTXE ComponentsDALjhi_service.exe" LOAD_ORDER_GROUP : TAG : 0 DISPLAY_NAME : Intel(R) Dynamic Application Loader Host Interface DEPENDENCIES : SERVICE_START_NAME : LocalSystem Security Risk: ============== The security risk of the unqoted service path privilege escalation vulnerability in the software process is estimated as medium.
