CVE-2025-24225 Overview
CVE-2025-24225 is an injection vulnerability in Apple iOS and iPadOS that enables user interface spoofing through crafted email messages. The flaw stems from improper input validation when processing email content, allowing an attacker to manipulate what the user sees in the Mail interface. Apple addressed the issue by improving input validation in iOS 18.5, iPadOS 18.5, and iPadOS 17.7.7. The vulnerability is tracked under CWE-79, reflecting improper neutralization of input during web page generation.
Critical Impact
Processing a maliciously crafted email can spoof the user interface, enabling phishing and social engineering attacks against iOS and iPadOS users.

Technical Details for CVE-2025-24225
Vulnerability Analysis
CVE-2025-24225 is an injection vulnerability affecting the email processing logic in Apple iOS and iPadOS. When the Mail component parses inbound message content, it fails to properly neutralize embedded markup or scripting constructs. This omission allows attacker-controlled input to alter the rendered interface presented to the user. The flaw is categorized under CWE-79, a class of issues where untrusted input is reflected into a rendering context without adequate sanitization.
The consequence is user interface spoofing rather than direct code execution. An attacker can craft email content that visually mimics legitimate application chrome, dialogs, or trust indicators. Users may be induced to disclose credentials, approve actions, or interact with content believing it originates from a trusted source.
Root Cause
The root cause is missing or insufficient input validation on email content processed by the Mail rendering pipeline. Apple's advisory states the issue was addressed with improved input validation, indicating attacker-controlled markup previously reached the rendering layer without adequate escaping or filtering. Consult Apple Support Document #122404 and Apple Support Document #122405 for vendor details.
Attack Vector
Exploitation requires the target to open or process a specially crafted email in the vulnerable Mail client. The attack vector is network-based, requiring user interaction to view the malicious message. No authentication or elevated privileges are required from the attacker to deliver the payload. Public technical discussion is available on the Full Disclosure Mailing List Post. No public proof-of-concept exploit is currently listed, and the CVE is not present on the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2025-24225
Indicators of Compromise
- Inbound emails containing unusual HTML markup, embedded scripting constructs, or malformed MIME structures designed to manipulate Mail rendering.
- User reports of Mail displaying unexpected dialogs, spoofed sender identities, or interface elements that mimic system prompts.
- Devices running iOS or iPadOS versions below 18.5 or iPadOS 17.7.7 that have not received the vendor patch.
Detection Strategies
- Inspect mail gateway logs for messages containing obfuscated HTML, unusual character encodings, or script-like payloads targeting mobile mail clients.
- Correlate device inventory data with OS version telemetry to identify endpoints still exposed to CVE-2025-24225.
- Monitor phishing report queues for user-submitted messages exhibiting UI spoofing characteristics on iOS Mail.
Monitoring Recommendations
- Enable content inspection on email security gateways to strip or neutralize active content in inbound HTML mail.
- Track iOS and iPadOS patch compliance across managed mobile fleets using MDM reporting.
- Increase user awareness training focused on spoofed interface indicators and unexpected credential prompts within Mail.
How to Mitigate CVE-2025-24225
Immediate Actions Required
- Update all iPhone devices to iOS 18.5 or later without delay.
- Update all iPad devices to iPadOS 18.5, or iPadOS 17.7.7 for supported legacy hardware.
- Enforce OS version compliance policies through mobile device management to block or quarantine non-compliant devices.
- Instruct users to avoid interacting with unsolicited emails and to verify sender identity through out-of-band channels.
Patch Information
Apple released fixes in iOS 18.5, iPadOS 18.5, and iPadOS 17.7.7. Detailed release notes are published in Apple Support Document #122404 and Apple Support Document #122405. Administrators should validate patch deployment through MDM inventory reports and confirm build numbers align with the patched releases.
Workarounds
- Configure email gateway policies to strip active HTML content and script constructs from messages destined for mobile clients until patches are applied.
- Restrict use of the native Mail application on unpatched devices through MDM configuration profiles where operationally feasible.
- Reinforce phishing awareness training with specific guidance on identifying spoofed Mail interface elements.
