CVE-2025-31210 is a denial-of-service (DoS) vulnerability affecting Apple iPadOS, specifically related to the processing of web content. The vulnerability arises from how the operating system handles certain web content, which can trigger resource exhaustion leading to a DoS condition. This issue is classified under CWE-400, indicating an uncontrolled resource consumption problem. The vulnerability does not impact confidentiality or integrity but severely affects availability by causing the device or application to become unresponsive or crash. Exploitation requires no privileges (AV:N), has low attack complexity (AC:L), does not require authentication (PR:N), but does require user interaction (UI:R), such as visiting a malicious web page or viewing crafted web content. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component without affecting other system components. Apple addressed this vulnerability by improving the user interface handling in iPadOS versions 17.7.7, iOS 18.5, and iPadOS 18.5. No known exploits are currently in the wild, but the medium CVSS score of 6.5 reflects the potential for disruption. The vulnerability highlights the risks associated with processing untrusted web content on mobile devices and the importance of timely patching to maintain device availability.

For European organizations, this vulnerability poses a risk primarily to availability of Apple iPad devices used within corporate environments. Organizations relying on iPads for critical business functions, remote work, or customer interactions could experience service interruptions if users encounter malicious web content designed to exploit this flaw. While the vulnerability does not compromise data confidentiality or integrity, the denial-of-service condition could disrupt workflows, reduce productivity, and potentially impact customer-facing services. Sectors such as healthcare, finance, education, and government, where iPads are commonly deployed for operational tasks, may face increased operational risks. Additionally, the requirement for user interaction means phishing or social engineering campaigns could be used to trigger the exploit, increasing the threat surface. The absence of known exploits in the wild currently reduces immediate risk, but the medium severity and ease of exploitation warrant proactive mitigation to prevent potential targeted attacks.

European organizations should prioritize updating all affected Apple devices to the patched versions: iPadOS 17.7.7, iOS 18.5, and iPadOS 18.5. Beyond patching, organizations should implement web content filtering and monitoring to reduce exposure to malicious or untrusted websites, especially on devices used in sensitive roles. User awareness training should emphasize the risks of interacting with unknown or suspicious web content to mitigate the user interaction requirement for exploitation. Network-level protections such as DNS filtering and secure web gateways can help block access to known malicious domains. For managed devices, enforcing mobile device management (MDM) policies to control app installations and web browsing behavior can further reduce risk. Incident response plans should include procedures for identifying and recovering from DoS conditions on iPads to minimize downtime. Regular vulnerability assessments and monitoring for unusual device behavior can aid in early detection of exploitation attempts.
