CVE-2020-9802 is a high-severity vulnerability in Apple iOS and related Apple operating systems and software products, including iPadOS, tvOS, watchOS, Safari, iTunes for Windows, and iCloud for Windows. The vulnerability arises from a logic issue in the processing of web content, which can be exploited by an attacker crafting malicious web content. When a vulnerable device processes this specially crafted content, it may lead to arbitrary code execution, allowing the attacker to run code of their choice on the affected device. This can compromise the confidentiality, integrity, and availability of the device and its data. The vulnerability has a CVSS v3.1 base score of 8.8, indicating high severity, with attack vector being network-based, requiring no privileges, but user interaction is needed (e.g., visiting a malicious website). The scope is unchanged, but the impact on confidentiality, integrity, and availability is high. Apple addressed this issue by implementing improved restrictions in iOS 13.5 and iPadOS 13.5, tvOS 13.4.5, watchOS 6.2.5, Safari 13.1.1, iTunes 12.10.7 for Windows, and iCloud for Windows 11.2 and 7.19. No known exploits in the wild have been reported to date. The vulnerability affects unspecified versions prior to these patches, so devices running older versions remain at risk. The attack vector involves web content processing, which means users could be compromised simply by visiting a malicious or compromised website or viewing malicious content delivered through web-based channels.

For European organizations, the impact of CVE-2020-9802 can be significant, especially for those with employees or customers using Apple devices. The arbitrary code execution capability could allow attackers to install malware, steal sensitive data, perform espionage, or disrupt operations. Sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the sensitive nature of their data and operations. The vulnerability's exploitation could lead to data breaches, loss of intellectual property, unauthorized access to corporate networks, and potential regulatory penalties under GDPR if personal data is compromised. Since the attack requires user interaction (e.g., visiting a malicious website), phishing campaigns or drive-by downloads could be effective vectors. The widespread use of Apple devices in Europe, including iPhones and iPads, increases the attack surface. Additionally, organizations using Apple software on Windows endpoints (iTunes, iCloud) are also exposed. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits over time.

1. Immediate patching: Organizations must ensure all Apple devices and software are updated to the fixed versions (iOS/iPadOS 13.5+, tvOS 13.4.5+, watchOS 6.2.5+, Safari 13.1.1+, iTunes 12.10.7 for Windows, iCloud for Windows 11.2+). 2. User awareness training: Educate users about the risks of visiting untrusted websites and opening unknown links, as user interaction is required for exploitation. 3. Web filtering and URL reputation services: Deploy advanced web filtering solutions to block access to known malicious sites and suspicious content. 4. Network monitoring: Implement network detection systems to identify unusual outbound connections or signs of compromise on Apple devices. 5. Application whitelisting and endpoint protection: Use endpoint security solutions that can detect and block suspicious code execution on Apple devices. 6. Restrict use of Apple software on Windows endpoints where possible or ensure they are kept up to date. 7. Incident response readiness: Prepare to respond to potential compromises by having forensic and remediation procedures in place specific to Apple device environments. 8. Limit unnecessary privileges on devices to reduce potential impact if exploited.
