Overview<\/strong><\/p>\n

CVE-2025-31237 is a significant vulnerability that affects macOS users. The flaw lies in the handling of AFP network shares, which, when maliciously crafted, can lead to an unexpected system termination. This vulnerability could potentially result in system compromise or data leakage, making it a critical issue for any organization or individual using the affected versions of macOS.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-31237
\nSeverity: High (CVSS: 7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: System termination, potential system compromise, and data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

macOS Ventura | 13.7.5 and below
\nmacOS Sequoia | 15.4 and below
\nmacOS Sonoma | 14.7.5 and below<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability lies in the mounting process of AFP network shares. When a maliciously crafted AFP network share is mounted, it can cause the system to terminate unexpectedly. This could potentially be used as a foothold for further attacks, leading to system compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

While the exact code to exploit this vulnerability is not disclosed to prevent misuse, a conceptual example might involve a malicious actor creating a specially crafted AFP share, which when accessed, causes the system to crash. The access might be achieved through a command like:<\/p>\n

mount_afp afp:\/\/[malicious_IP]\/[malicious_share] \/Volumes\/[mount_point]<\/code><\/pre>\n
The `[malicious_share]` would be configured in such a way that it exploits the vulnerability when mounted.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Users of affected macOS versions are advised to update to macOS Ventura 13.7.6, macOS Sequoia 15.5, or macOS Sonoma 14.7.6 where the issue has been resolved. Until the update can be applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
