Lifecycle Timeline
1DescriptionCVE.org
Uncontrolled search path for some EquiTriton before version f5ddbb5 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
Privilege escalation in EquiTriton before commit f5ddbb5 arises from an uncontrolled search path element (CWE-427) within Ring 3 user-mode application components, allowing a local attacker operating under a high-privilege user context to substitute a malicious binary or library in a search path directory that EquiTriton resolves ahead of its legitimate target. Successful exploitation yields full confidentiality, integrity, and availability compromise of the vulnerable system while leaving downstream systems unaffected. No public exploit code has been identified and this CVE does not appear in the CISA KEV catalog at time of analysis; Intel disclosed the issue under advisory INTEL-SA-01473.
Technical ContextAI
CWE-427 (Uncontrolled Search Path Element) describes a class of vulnerabilities in which an application locates executable code - DLLs, shared objects, or helper binaries - by walking a sequence of directories that an attacker can partially control. EquiTriton's affected components operate in Ring 3 (x86 user mode), meaning the search path manipulation does not require kernel-level access, but the application's privilege context at load time enables escalation. The CPE string cpe:2.3:a:n/a:equitriton:*:*:*:*:*:*:*:* covers all EquiTriton application variants prior to upstream commit f5ddbb5; the vendor field is recorded as 'n/a' in the NVD, indicating limited formal product cataloguing. The CVSS 4.0 metric AT:P (Attack Requirements: Present) signals that exploitation depends on a specific non-default precondition - namely, a writable directory appearing in the application's search order before the legitimate binary path.
RemediationAI
Organizations should update their EquiTriton installation to incorporate upstream commit f5ddbb5 or any subsequent build that includes it; because no formally tagged patched release version has been confirmed in available data, teams building from source must verify their checkout is at or beyond that commit hash. Where immediate patching is not feasible, administrators should audit all directories included in EquiTriton's executable and library search path and revoke write permissions for any accounts other than those strictly required for deployment - this directly eliminates the condition (AT:P) that makes the vulnerability exploitable. As a secondary compensating control, deploying application whitelisting (e.g., Windows AppLocker, SELinux file contexts, or equivalent) to prevent unauthorized binaries from executing from those search path locations reduces residual risk; note that whitelisting misconfiguration can cause application breakage and should be tested before deployment.
