CVE-2019-8773

22
FAUCET Score

CVE-2019-8773 is a critical memory corruption vulnerability affecting multiple Apple products, including Safari, iOS, iPadOS, iCloud for Windows, tvOS, watchOS, and iTunes for Windows. This flaw, addressed with improved memory handling in various updates, could allow an attacker to achieve arbitrary code execution by tricking a user into processing maliciously crafted web content. With a CVSS score of 8.8 (High), it presents a significant risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While no public exploits (Metasploit, Nuclei, ExploitDB) are currently known, and it is not listed in CISA's KEV catalog, the vulnerability's potential for arbitrary code execution warrants prompt patching. Community discussion and media coverage for this CVE are minimal, which is typical for the vast majority of vulnerabilities.
