CVE-2024-44308 is a code execution vulnerability in Apple Multiple Products. CISA added it to the Known Exploited Vulnerabilities catalogue on 21 November 2024, which means attackers have used it in real attacks. Apple iOS, macOS, and other Apple products contain an unspecified vulnerability when processing maliciously crafted web content that may lead to arbitrary code execution.
What this vulnerability class means
This is a remote code execution flaw in a widely deployed consumer and enterprise platform, so the danger is not limited to one app or one user workflow. A malicious web payload can turn routine browsing or in-app rendering into an execution path on the device, which makes the issue especially serious for systems that process untrusted web content frequently.
For the exact record, the authoritative starting points are the CVE Program and the NIST National Vulnerability Database, which provide the canonical vulnerability entry and supporting record details.
Why malicious web content is dangerous here
Web content is a high-risk input because it is designed to be parsed, rendered, and interpreted automatically. When that parser or rendering path is vulnerable, the attacker does not need the victim to install a file or approve a suspicious action, only to encounter content that the product handles in a vulnerable way.
That matters because code execution on a trusted endpoint can be the first step in broader compromise, including data theft, credential theft, persistence, and movement into other accounts or services reachable from the device. The browser or embedded web engine becomes the delivery surface, but the blast radius often extends beyond the initial application.
For defenders, this class of issue is especially important in ecosystems where the same device also holds sign-in sessions, synced browser data, developer tooling, or administrative access. That is why a vulnerability like this is usually treated as both an endpoint security issue and an identity exposure issue once exploitation occurs.
How organisations assess exposure and reduce attack surface
Exposure assessment starts with knowing where the affected Apple products exist, which users rely on them, and which devices are internet-facing or frequently exposed to untrusted content. Asset inventory matters because the fastest way to miss a critical exploit is to assume only obvious desktops or phones are at risk.
Organisations should also review vendor guidance and the CISA KEV catalogue to confirm whether the issue is actively exploited and to prioritise remediation accordingly. The CISA Known Exploited Vulnerabilities catalogue is the operational reference for exploitation status, while vendor advisories remain the source for platform-specific patch and mitigation details.
Where patching is delayed, compensating controls include restricting exposure to untrusted web content, tightening browser and content-filtering policies, and reducing administrative privileges on endpoints that must remain online. Organisations should also assume that any session or secret accessible on the device may need review if exploitation is suspected.
Detection, recovery, and post-exploitation review
Detection is difficult because successful exploitation may look like ordinary application activity at first. That makes post-patch review important: teams should look for unusual process launches, unexpected child processes from browser or web-rendering components, new persistence mechanisms, and suspicious outbound connections from the affected endpoint.
If there is evidence of compromise, treat the device as a potential source of stolen session material or credentials. The practical response is to investigate access logs, invalidate active sessions where appropriate, and rotate any secrets that may have been exposed on the system, especially for administrative or developer accounts.
Where available, endpoint telemetry, browser logs, and EDR detections should be reviewed together so that the investigation covers both the original execution path and any follow-on activity. In cases like this, patching closes the vulnerability, but it does not by itself prove the system was not already used as an initial foothold.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST CSF 2.0, NIST SP 800-53 Rev 5 and CIS Controls v8 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | DE.CM-01 — Networks and systems are monitored to detect potential cybersecurity events | Actively monitor affected Apple endpoints for exploitation signs and post-patch anomalies. |
| RS.MA-01 — Incidents are contained | Remote code execution requires rapid containment once suspicious execution is observed. | |
| Recommendation — Correlate endpoint telemetry and browser activity to detect exploitation attempts on exposed Apple devices. Isolate suspected Apple endpoints quickly to contain possible code execution and follow-on activity. | ||
| NIST SP 800-53 Rev 5 | SI-3 — Malicious Code Protection | Malicious web content can deliver code through web-facing parsing and rendering paths. |
| IR-4 — Incident Handling | Suspected exploitation needs coordinated investigation, containment, and recovery. | |
| Recommendation — Strengthen malicious-content controls on Apple endpoints and browsers to reduce exploit delivery. Use incident-handling procedures to investigate, isolate, and recover compromised Apple systems. | ||
| CIS Controls v8 | CIS-7 — Continuous Vulnerability Management | KEV-listed exploitation requires prioritised vulnerability remediation and verification. |
| Recommendation — Prioritise patching and verification for Apple devices exposed to the exploited vulnerability. | ||
