CVE-2017-2373: An issue was discovered in certain Apple products.

An issue was discovered in certain Apple products. iOS before 10.2.1 is affected. Safari before 10.0.3 is affected. tvOS before 10.1.1 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

Security readout for executives and security teams

Plain-English summary

CVE-2017-2373 is a WebKit flaw in older Apple software. A malicious website could make the browser or app crash, and the CVE description says remote code execution is possible. Exposure is mainly legacy iOS, Safari, and tvOS versions that missed Apple security updates.

Executive priority

Treat this as a legacy exposure cleanup item with high impact if present. It is not KEV-listed in the supplied data, but remote code execution through web content and public exploit references justify prompt remediation of any remaining vulnerable systems.

Technical view

The issue affects WebKit in iOS before 10.2.1, Safari before 10.0.3, and tvOS before 10.1.1. The public description characterizes it as memory corruption reachable through crafted web content, causing application crash or arbitrary code execution.

Likely exposure

Likely exposure is limited to outdated Apple devices or Safari installations still below the fixed versions. Modern, supported systems should generally be patched, but unmanaged legacy devices, kiosks, labs, or embedded Apple TV deployments can retain risk.

Exploitation context

The source bundle includes an Exploit-DB reference, so public exploit material exists. CISA KEV status is false in the supplied data, and no cited source in the bundle establishes active exploitation in the wild.

Researcher notes

Evidence is limited to public CVE metadata and linked advisories. The affected component is WebKit, with memory corruption triggered by crafted web content. The bundle does not provide CVSS, CWE, patch implementation details, or confirmed in-the-wild exploitation.

Mitigation direction

  • Update iOS to 10.2.1 or later where supported.
  • Update Safari to 10.0.3 or later where supported.
  • Update tvOS to 10.1.1 or later where supported.
  • Retire or isolate Apple systems that cannot receive vendor fixes.
  • Check Apple and platform vendor advisories for current supported upgrade paths.

Validation and detection

  • Inventory Apple endpoints and record iOS, Safari, and tvOS versions.
  • Flag systems below iOS 10.2.1, Safari 10.0.3, or tvOS 10.1.1.
  • Confirm endpoint management reports show the relevant security updates installed.
  • Review vulnerability scanner results for CVE-2017-2373 coverage.
  • Check for unsupported legacy devices still used for web browsing.
