Exploitation Conditions

Requires local physical access (AV:P) to a Dell system with the OS Recovery tool installed at a version prior to 2.4.4; the tool ships with a hard-coded cryptographic key (CWE-321), so an attacker who extracts that embedded key can disclose information it was meant to protect. No authentication is needed (PR:N) and no user interaction is required (UI:N), but the physical-access requirement is the decisive limiter: remote or network exploitation is not possible, impact is limited to confidentiality only (C:L, no integrity or availability effect), and installations updated to 2.4.4 or later are not affected.

Impact

This is a low-priority, low-real-risk issue despite being a cryptographic-key weakness (CWE-321). The CVSS 3.1 score of 2.4 (AV:P/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) reflects the dominant limiting factor: AV:P means exploitation requires physical access to the machine, which collapses realistic attack surface dramatically. Impact is confined to low confidentiality (C:L) with no integrity or availability impact. The vuln.today decision label is 'monitor', the weakest urgency tier, and this is consistent with the signals: there is no CISA KEV listing, no EPSS score was supplied, and no PoC or exploit reference is present. No signals conflict - every indicator (physical-only vector, low confidentiality-only impact, 'monitor' label, absence of exploitation evidence) points the same direction. The one data caveat is the sole reference: it is a Dell BIOS advisory (DSA-2026-230, 'multiple AMI BIOS vulnerabilities'), which does not obviously correspond to the Dell OS Recovery Tool named in this CVE - verify the correct advisory with Dell before acting on remediation details.

Exploit ScenarioDerived

An attacker with hands-on physical access to a Dell system running the OS Recovery tool (prior to 2.4.4) recovers a cryptographic key that is hard-coded into the software and identical across installations, then uses it to decrypt or access protected information handled by the tool. Because the key is embedded rather than per-device, knowledge of it generalizes across affected systems. No public exploit has been identified at time of analysis, and exploitation still requires local physical presence.

Monitor Track and reassess. Why: LOW severity (CVSS 0.1-3.9).

AnalysisAIv1 – Nov 03, 2026

Information disclosure in Dell's OS Recovery Tool (versions prior to 2.4.4) stems from a hard-coded cryptographic key embedded in the application (CWE-321), which an attacker who can extract it may use to recover data the key was intended to protect. Exploitation is gated by the CVSS vector's physical-access requirement (AV:P); no authentication (PR:N) or user interaction (UI:N) is needed once an attacker is at the machine, and impact is confined to partial confidentiality loss (C:L) with no integrity or availability effect, giving a low 2.4 base score and a 'monitor' priority. No public exploit code was identified at time of analysis, and installations on 2.4.4 or later are not affected.

RemediationAI

Update the Dell OS Recovery Tool to version 2.4.4 or later, the fixed release identified by the 'prior to 2.4.4' affected range; installations at 2.4.4 and above are not affected, and no separate workaround is documented in the supplied data. Confirm the applicable Dell advisory, referenced as https://www.dell.com/support/kbdoc/en-us/000516289/dsa-2026-230-security-update-for-dell-client-platform-bios-for-multiple-ami-bios-vulnerabilities, and verify that it addresses the recovery tool rather than only the BIOS content its title suggests. Because the key is hard-coded rather than configurable, replacing the tool binary with the fixed build is the only remediation the evidence supports, and exposure reduction in the interim depends on the prerequisite the CVSS vector already imposes, namely limiting physical access to systems that have the pre-2.4.4 tool installed.

Technical ContextAI · show details

The flaw is a use of a hard-coded cryptographic key (CWE-321) in Dell's OS Recovery Tool, a Windows utility used to build recovery media and restore a Dell system image. Because the key is static and shipped inside the tool rather than derived per-installation or per-session, anyone who obtains the binary or its installed files can retrieve the same key material that every other installation uses; the weakness is therefore one of key management rather than of a memory-safety or logic bug. The CPE cpe:2.3:a:dell:os_recovery_tool:*:*:*:*:*:*:*:* confirms the affected component is the recovery tool itself, not the BIOS or firmware, and the CVSS vector CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N shows the attacker must have physical access to the host (AV:P) while the attack itself is straightforward once that access exists. The supplied sources do not describe which specific data the hard-coded key protects or the exact extraction path, so the precise trigger and the scope of the disclosed information remain unverified beyond the stated confidentiality impact.

Physical access drives AV:P; a static hard-coded key needs no privileges (PR:N) or interaction and is reliably recoverable (AC:L); impact is confidentiality-only and limited (C:L, I:N, A:N).
