Uncontrolled search path for some Intel(R) Server Firmware Update Utility Software before version 16.0.12. within Ring 3: User Applications may allow an escalation of privilege. System software adversary with an authenticated user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
AnalysisAI
Privilege escalation in Intel Server Firmware Update Utility Software before version 16.0.12 exposes authenticated local users to an uncontrolled search path (DLL/library hijacking) condition within the Ring 3 user-application layer. A low-privileged local attacker who can plant a malicious library or executable in a directory the utility searches at launch can escalate privileges with high impact to confidentiality, integrity, and availability of the affected system. No public exploit is identified at time of analysis, and EPSS sits at the 3rd percentile, consistent with SSVC exploitation status of 'none'.
Technical ContextAI
CWE-427 (Uncontrolled Search Path Element) describes a class of vulnerabilities where an application resolves the location of executables, shared libraries, or plugins using a caller-influenced path - such as the current working directory, PATH, or LD_LIBRARY_PATH - before checking trusted system locations. In this case, the Intel Server Firmware Update Utility (CPE: cpe:2.3:a:n/a:intel(r)_server_firmware_update_utility_software) operates in Ring 3 (user-space) and fails to restrict where it loads supporting components. On Windows, this commonly manifests as DLL search order hijacking; on Linux, as shared-object or PATH hijacking. The vulnerability is constrained to user-space and does not directly implicate firmware or hypervisor layers, but the resulting privilege escalation has full system-level C/I/A impact on the vulnerable host.
RemediationAI
The primary fix is upgrading to Intel Server Firmware Update Utility Software version 16.0.12 or later, as confirmed by Intel advisory INTEL-SA-01410 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01410.html). Until patching is feasible, restrict write access to directories on the system PATH and to the utility's installation and working directories, ensuring low-privileged users cannot plant files in locations the utility resolves at runtime - this is the most targeted compensating control with minimal operational side effect. Additionally, running the utility only from a controlled administrative account (PR:H context) eliminates the low-privilege attack path entirely. Avoid executing the utility from shared or world-writable directories such as temp folders or network shares, as these are common hijack staging grounds.
