An improper certificate validation issue was discovered in NXP i.MX 28 i.MX 50, i.MX 53, i.MX 7Solo i.MX 7Dual Vybrid VF3xx, Vybrid VF5xx, Vybrid VF6xx, i.MX 6ULL, i.MX 6UltraLite, i.MX 6SoloLite, i.MX 6Solo, i.MX 6DualLite, i.MX 6SoloX, i.MX 6Dual, i.MX 6Quad, i.MX 6DualPlus, and i.MX 6QuadPlus. When the device is configured in security enabled configuration, under certain conditions it is possible to bypass the signature verification by using a specially crafted certificate leading to the execution of an unsigned image.

Remediation

Which version to upgrade to

Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.

No fix version is recorded for this entry. Check the references for vendor advisories.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Weakness class (CWE)

CWE-295 · Improper Certificate Validation

Root cause

A certificate validation error is silently swallowed instead of terminating the connection. Often, code added for a test environment makes its way into production.

The bug in code

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.
