Lifecycle Timeline
1DescriptionCVE.org
Uncontrolled search path for some Approximate Bayesian Inference Framework before version on commit #484c949 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with a privileged user combined with a low 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 passive 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
Local privilege escalation via uncontrolled search path (DLL/binary planting) affects Intel's Approximate Bayesian Inference Framework prior to commit #484c949. An attacker operating at Ring 3 (user application space) with high privileges who can manipulate the search path can cause a co-located privileged user to load a malicious binary, resulting in full compromise of confidentiality, integrity, and availability on the vulnerable system. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
Technical ContextAI
CWE-427 (Uncontrolled Search Path Element) describes vulnerabilities where an application loads a library or executable by searching a set of directories controlled by an attacker - commonly called DLL hijacking, binary planting, or search-order hijacking. The affected product is Intel's Approximate Bayesian Inference Framework (CPE: cpe:2.3:a:n/a:approximate_bayesian_inference_framework:*:*:*:*:*:*:*:*), an AI/ML research library. The vulnerability is scoped to Ring 3 (user-mode applications), meaning it does not directly involve kernel or firmware components. The CVSS 4.0 vector (AV:L/AC:L/AT:P) indicates local access with low attack complexity but with specific attack requirements present - consistent with a scenario where an attacker must pre-position a malicious file in a directory searched by the framework before a privileged user triggers the load.
RemediationAI
Upstream fix available via commit #484c949 in the Approximate Bayesian Inference Framework repository; a formally tagged release version has not been independently confirmed from available data. Organizations using this framework should update to at least commit #484c949 as directed by Intel advisory intel-sa-01486 (https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01486.html). As a compensating control pending update, administrators should restrict write access to directories on the application's search path to prevent unprivileged users from planting malicious binaries - this can be enforced via filesystem ACLs (e.g., chmod o-w on relevant directories on Linux, or restricting write permissions via Group Policy on Windows). Additionally, running the framework process under a least-privilege account reduces the attractiveness of the escalation target. Note that ACL-based controls are bypassable if the attacker already holds write access through another vulnerability.
