Vulnerability Data

Snap One OvrC Pro devices versions 7.2 and prior do not validate firmware updates correctly. The device only calculates the MD5 hash of the firmware and does not check using a private-public key mechanism. The lack of complete PKI system…

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-345 CWE-354

Requires explicit verification of data authenticity from authoritative sources, preventing acceptance of unauthenticated resolution responses.

addresses: CWE-345 CWE-354

Control requires verification of data authenticity/integrity (e.g., checksums) after aggregation/packing, directly reducing exploitation of insufficient verification before transmission.

addresses: CWE-354 CWE-345

Requires use of proper integrity verification tools, reducing the chance an incorrect check value is accepted.

addresses: CWE-345 CWE-354

The control implements verification mechanisms that detect tampering by ensuring data authenticity.

addresses: CWE-345

Directly requires independent verification of matching output before adverse decisions, mitigating insufficient authenticity checks on data from external sources.

addresses: CWE-354

Proper validation of integrity check values is required for reliable tamper detection, directly reducing undetected modification risks.

addresses: CWE-345

Use of approved PKI certificates provides verifiable data authenticity and origin for communications and artifacts.

addresses: CWE-345

Mandates provision of authenticity and integrity artifacts that enable verification of name/address resolution data.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-01 mostly match
prevents

Requires cryptographic hashes and signatures that directly enforce integrity-check validation for data at rest.

PR.DS-02 mostly match
prevents

Requires cryptographic hashes and signatures that directly enforce integrity-check validation for data in transit.

RC.RP-05 mostly match
degrades

CWE-345 directly impairs RC.RP-05's verification of restored-asset integrity/authenticity, largely defeating the outcome while still leaving other restoration-confirmation steps partially viable.

ID.RA-09 partial match
prevents

Mandates pre-acquisition integrity assessment, addressing only the initial portion of the weakness lifecycle.

RC.RP-03 partial match
prevents

Requires verification of backup integrity, covering validation only within recovery scenarios.

prevents

Cryptographic controls mandate integrity mechanisms whose correct validation directly prevents CWE-354.

prevents

Secure coding standards require proper implementation and validation of checksums or MACs.

finds

Security testing can detect missing integrity validation but does not itself implement the control.

mitigates

Network controls can enforce authenticated channels, reducing risk of accepting unauthentic data.

mitigates

Secure network services often include authenticity checks for data exchanged over those services.

prevents

Secure SDLC incorporates authenticity verification requirements throughout development.
