CVE-2024-44309: XSS Vulnerability in Apple Ecosystem

Historical catalog analysis: CISA added this entry on November 21, 2024. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2024-44309 is a Cross-Site Scripting (XSS) vulnerability (CWE-79) affecting multiple Apple products. The flaw is triggered when a device processes maliciously crafted web content, which could allow for the execution of unauthorized scripts in the context of the affected application.

Exposure and applicability

This vulnerability applies to a broad range of Apple hardware and software, specifically including iOS and macOS, as well as other unspecified Apple products. The primary exposure path is the processing of malicious web content; therefore, any asset within the organization’s inventory running these operating systems that accesses web-based resources is potentially applicable.

Remediation priorities

Because this vulnerability has been added to the CISA Known Exploited Vulnerabilities (KEV) catalog as of November 21, 2024, it should be prioritized for immediate remediation. Our analysis suggests the following priority sequence:

1. Asset Identification: Identify all Apple devices across the environment, including mobile handsets (iOS) and workstations (macOS).
2. Update Deployment: Apply the mitigations provided in the vendor’s official support documentation.
3. Decommissioning: In scenarios where a mitigation is unavailable for a legacy device, the source indicates that discontinuing use of the product is the required action to eliminate exposure.

How to validate remediation

Verification must move beyond simple version checks to ensure the vulnerability is no longer exploitable in the specific environment. We recommend the following validation approach:

• Deployment Confirmation: Verify through centralized device management (MDM) or system reports that the vendor-recommended updates have been successfully installed across all identified assets.
• Configuration Audit: Ensure that web-facing applications on these devices are not bypassing security controls that would otherwise mitigate XSS risks.
• Residual Risk Assessment: Acknowledge that while a patch addresses the specific flaw in CVE-2024-44309, it does not eliminate the general risk of XSS from other undiscovered vulnerabilities. Validation should include confirming that the device is running the latest supported security baseline.

Limits and open questions

The source identifies “other Apple products” beyond iOS and macOS but does not explicitly list every affected product line. This creates a visibility gap for vulnerability management teams who may have specialized Apple hardware in their environment. Additionally, while CISA has flagged this as known to be exploited, the specific nature of the active exploits and the exact versions of the software that are vulnerable remain dependent on the vendor’s detailed support documentation.
