CVE-2025-5833: Pioneer DMH-WT7600NEX Root Filesystem Insufficient Verification of Data Authenticity Vulnerability

Noroxi assessment

Priority: Monitor (action score 27/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.26% (FIRST EPSS).
  • Physical access to the device is required. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Severity is disputed: the assigning authority (CNA) scores it 4.6, NVD 6.8.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Pioneer DMH-WT7600NEX Root Filesystem Insufficient Verification of Data Authenticity Vulnerability. This vulnerability allows physically present attackers to bypass authentication on affected installations of Pioneer DMH-WT7600NEX devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the configuration of the operating system. The issue results from the lack of properly configured protection for the root file system. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-26077.
