Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Physical: The attack requires the attacker to physically touch or manipulate the vulnerable component. Physical interaction may be brief or persistent.
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Dell SupportAssist OS Recovery to 5.5.14.0.

AI-suggested

1. Update Dell SupportAssist OS Recovery to version 5.5.14.0 or later as soon as an official patch or update is released by Dell to remediate this vulnerability. 2. Enforce strict physical security controls to prevent unauthorized physical access to devices, including secure storage, access logging, and surveillance in sensitive areas. 3. Implement full disk encryption on affected systems to protect data at rest, ensuring that recovery environments do not expose unencrypted sensitive information. 4. Restrict access to recovery environments by configuring BIOS/UEFI passwords and disabling boot from external media where possible to limit unauthorized recovery attempts. 5. Conduct regular audits of device inventory and physical access policies to detect and prevent potential insider threats or device theft. 6. Educate staff on the importance of physical security and the risks associated with device loss or theft, emphasizing the need to report missing hardware promptly. 7. 8. Consider deploying endpoint detection and response (EDR) solutions that can alert on unusual physical access or recovery environment usage.

Description

Dell SupportAssist OS Recovery, versions prior to 5.5.14.0, contains an Exposure of Sensitive Information to an Unauthorized Actor vulnerability. An unauthenticated attacker with physical access could potentially exploit this vulnerability, leading to Information Disclosure.

Impact

For European organizations, the impact of CVE-2025-38746 is primarily related to the confidentiality of sensitive information stored or accessible via Dell SupportAssist OS Recovery. Organizations with Dell systems using vulnerable versions could face risks if devices are lost, stolen, or accessed by unauthorized personnel. This could lead to exposure of recovery data or system information that might aid further attacks or data breaches. While the vulnerability does not directly compromise system availability or integrity at a large scale, the exposure of sensitive information could undermine trust, violate data protection regulations such as GDPR, and potentially facilitate subsequent attacks. The requirement for physical access reduces the likelihood of remote exploitation but increases the importance of physical security controls. Organizations with high-value or sensitive data on Dell devices should be particularly cautious, as attackers with physical access could leverage this vulnerability to gain insights into system configurations or recovery mechanisms. In environments with shared or public access to hardware, such as universities, public institutions, or co-working spaces, the risk is elevated. Overall, the vulnerability represents a low-severity but non-negligible risk that should be addressed to maintain compliance and protect sensitive information.

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
