Scope: Unchanged
Confidentiality: High
Integrity: High
Availability: High

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Oct 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 2026-10-26.

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

AI-suggested

1. Apply vendor patches or updates as soon as they are released to address the DLL search path issue. 2. Until patches are available, run installers with the least privilege necessary, avoiding administrative accounts where possible. 3. Use application whitelisting and restrict write permissions on directories involved in DLL loading to prevent unauthorized DLL placement. 4. Employ endpoint detection and response (EDR) tools to monitor for suspicious DLL loads or installer behaviors. 5. Educate users to verify the integrity and source of installers before execution and avoid running installers from untrusted locations. 6. Consider using tools like Microsoft's Process Monitor to audit DLL loading paths during installation to detect anomalies. 7. Implement network segmentation to limit the impact of a compromised endpoint. 8. Review and harden system environment variables and PATH settings to reduce the risk of DLL hijacking. 9. Maintain an inventory of systems running DENSO TEN software to prioritize remediation efforts. 10. Coordinate with vendors and cybersecurity teams to receive timely threat intelligence and updates.

Description

The installers of DENSO TEN drive recorder viewer contain an issue with the DLL search path, which may lead to insecurely loading Dynamic Link Libraries. As a result, arbitrary code may be executed with the privilege of the user invoking the installer.

Impact

For European organizations, the impact of CVE-2025-57781 can be substantial, particularly in industries that rely on vehicle drive recorder technology, including automotive manufacturing, transportation logistics, public safety, and law enforcement. Exploitation could allow attackers to execute arbitrary code with user-level privileges during software installation, potentially leading to unauthorized access to sensitive vehicle data, manipulation of recorded footage, or disruption of critical monitoring systems. This could compromise the integrity and availability of forensic data used in accident investigations or fleet management. Additionally, if attackers escalate privileges post-exploitation, broader system compromise is possible, affecting network security and operational continuity. The vulnerability also poses a risk to supply chain security, as compromised installers could be distributed within organizations. Given the high CVSS score and the potential for privilege escalation, European organizations must treat this vulnerability as a serious threat to operational security and data confidentiality.
