Summary

CVE-2024-9493 is a high-severity Uncontrolled Search Path Element (CWE-427) vulnerability in Silabs (inferred from references). Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-9493 is a DLL hijacking vulnerability stemming from an uncontrolled search path (CWE-427) in the ToolStick installer from Silicon Labs. This flaw affects users running the impacted installer, enabling malicious DLL loading during execution. The vulnerability carries a CVSS v3.1 base score of 8.6 (AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H), indicating high severity due to its potential for significant impact with local access and user interaction.

A local attacker with no required privileges can exploit this by placing a malicious DLL in a directory included in the installer's search path. When a user runs the ToolStick installer, it loads the attacker's DLL instead of the legitimate one, resulting in privilege escalation and arbitrary code execution with the installer's privileges.

Silicon Labs has published an advisory on their community site (https://community.silabs.com/068Vm00000JUQwd) addressing the issue, with details on mitigations for affected ToolStick installer versions.

Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Establishes restrictive configuration settings that can define and lock down approved search paths.

AC-3 Access Enforcement partial match

Enforces approved authorizations so that only intended actors can place or modify elements in the search path.

AC-6 Least Privilege partial match

Limits privileges so unintended actors cannot write to or control directories in the product's search path.

CM-5 Access Restrictions for Change partial match

Restricts logical and physical access to change system configuration, including search-path settings and directories.
