CVE-2017-2498
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in certain Apple products. iOS before 10.3.2 is affected. The issue involves the "Security" component. It allows attackers to bypass intended access restrictions via an untrusted certificate.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a certificate validation bypass vulnerability in iOS Security component prior to version 10.3.2. The flaw allows untrusted certificates to be accepted where they should be rejected, enabling attackers to bypass intended access restrictions by presenting improperly validated certificates.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check the iOS version installed on the deviceOn the iOS device, go to Settings > General > About and look at the 'Version' field. Alternatively, connect the device to a computer with iTunes or Finder and view the device summary page which displays the iOS version.Affected if The version displayed is 10.3.1 or earlier (for example, 10.3.1, 10.3.0, 10.2.x, or any version in the 10.x series prior to 10.3.2)
-
Verify the iOS build number for precise version matchingIn Settings > General > About, locate the 'Build Number' field. Compare this against Apple's official build numbers for iOS 10.3.2 to confirm whether an update to 10.3.2 has been applied.Affected if The build number corresponds to an iOS version prior to the 10.3.2 release for your specific device model
The device is affected if it is running any iOS version 10.3.1 or earlier, since the certificate validation bypass vulnerability exists in those versions and was patched in iOS 10.3.2.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply iOS security update 10.3.2 or later to affected devices to remediate the certificate validation bypass.
