Exploitation Conditions

Exploitation requires all of the following: local physical access to a Dell machine that has Dell OS Recovery Tool prior to version 2.4.4 installed, an already-provisioned low-privileged local account (PR:L), and user interaction with the tool (UI:R) to trigger access to the insecurely stored data. Limiting factors are significant: the Physical attack vector (AV:P) rules out any remote or network-based exploitation, the tool must be present and in a vulnerable version, and only Low confidentiality data is exposed with no integrity or availability impact. These constraints confine realistic risk to an insider or someone with hands-on device access.

Impact

This is a low-priority vulnerability by every available signal. The CVSS base score is only 2.2, and the vector (CVSS:3.1/AV:P/AC:L/PR:L/UI:R/S:C/C:L/I:N/A:N) confirms the constraining factors: Physical attack vector (AV:P), an already-present low-privileged account (PR:L), and required user interaction (UI:R), yielding only Low confidentiality impact with no integrity or availability impact. No EPSS score, KEV listing, or public POC is present in the provided data, so exploitation status is 'no public exploit identified at time of analysis.' The combination of required physical access plus local authentication plus user interaction makes mass or remote exploitation infeasible - this is not a scalable threat. The one internally notable choice is the Scope:Changed metric Dell assigned, implying the insecurely stored data (CWE-922) may grant access to resources beyond the tool itself; this is the only reason the score is not even lower. No signals conflict: all indicators (low CVSS, physical vector, absence of EPSS/KEV/POC) point consistently to a low real-world risk. The CVSS vector and the textual description also agree - both describe a local/physical, low-privilege scenario.

Exploit ScenarioDerived

An attacker with physical access to a Dell computer and a low-privileged local account launches or interacts with the Dell OS Recovery Tool (version prior to 2.4.4) and reads sensitive information that the tool stored insecurely on disk. No public exploit code is identified, and the physical-access and user-interaction requirements make this a targeted, hands-on-keyboard scenario rather than a scalable attack.

AnalysisAIv1 – Oct 14, 2026

Information disclosure in Dell OS Recovery Tool versions prior to 2.4.4 allows a low-privileged local account, combined with physical access to the machine and user interaction with the tool, to read sensitive information that the application stores insecurely on disk. The exposure is limited by design: the attack vector is physical (AV:P), authentication is required at the low-privilege level (PR:L), and the only impact is Low confidentiality (C:L) with no integrity or availability effect, producing a CVSS base score of just 2.2. There is no public exploit code identified at time of analysis and the issue is not confirmed as actively exploited (CISA KEV); remediation is available by upgrading to Dell OS Recovery Tool 2.4.4 or later per Dell DSA-2026-450.

RemediationAI

Apply the vendor fix by upgrading Dell OS Recovery Tool to version 2.4.4 or later, as documented in Dell security advisory DSA-2026-450 (https://www.dell.com/support/kbdoc/en-us/000517461/dsa-2026-450-security-update-for-dell-os-recovery-tool-for-an-insecure-storage-of-sensitive-information-vulnerability); this is a vendor-released patch and is the only complete remediation. If the tool is not operationally required on a given endpoint, uninstall it, which removes the exposure entirely at the cost of losing the recovery-media creation capability on that machine. Where the tool must remain, reduce the attack surface by restricting physical and console access to trusted staff only, avoiding the use of the tool on shared, kiosk, or multi-user workstations, running it under a dedicated low-value account rather than a privileged one, and deleting any recovery artifacts, working directories, and temporary files the tool leaves behind after each use - though these are partial mitigations because they reduce who can reach the insecurely stored data and how long it persists rather than fixing the underlying storage flaw, and they add an operational cleanup burden that can be missed. There is no network-facing component to firewall off, since exploitation requires physical presence (AV:P); monitoring should therefore focus on account and file-access auditing for unexpected reads of tool-related directories by non-administrative users.

Technical ContextAI · show details

The root cause is CWE-922 (Insecure Storage of Sensitive Information), a weakness class in which an application persists sensitive data - credentials, tokens, configuration secrets, or recovery artifacts - in a location or format that is not adequately protected against access by other local users or processes. In Dell OS Recovery Tool, the affected component writes such data to a predictable, insufficiently permissioned location on the local filesystem, allowing a user with an existing low-privileged account who also has physical hands-on access to the device to retrieve it. The CVSS:3.1 vector AV:P/AC:L/PR:L/UI:R/S:C/C:L/I:N/A:N confirms that exploitation is local and physical only (AV:P) rather than network reachable, needs low privileges already provisioned on the host (PR:L), requires the user to interact with the tool (UI:R) so the vulnerable code path executes, and results in a Scope Changed (S:C) condition - the vulnerable component affects resources beyond its own security scope, such as data belonging to other users or the host - but only with Low confidentiality impact and no integrity or availability loss. Because the tool is a Windows utility used to build USB recovery media for Dell systems and can run with elevated rights, the most plausible sensitive content is credential or recovery material left on disk that an ordinary local user should not be able to read.
