This issue was addressed with additional entitlement checks. This issue is fixed in macOS Sonoma 14.7.6, iPadOS 17.7.7, iOS 18.5 and iPadOS 18.5, visionOS 2.5, macOS Ventura 13.7.6, macOS Sequoia 15.4. An attacker may be able to turn on sharing of an iCloud folder without authentication.

The remote host is running a version of macOS / Mac OS X that is 13.x prior to 13.7.6. It is, therefore, affected by multiple vulnerabilities:

  - A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity     expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat     can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could     lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the     environment and library usage. (CVE-2024-8176)

Note that Nessus has not tested for these issues but has instead relied only on the operating system's self-reported version number.

The version of Apple iOS running on the mobile device is prior to 18.5. It is, therefore, affected by multiple vulnerabilities.

The remote host is running a version of macOS / Mac OS X that is 14.x prior to 14.7.6. It is, therefore, affected by multiple vulnerabilities:

  - A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle     attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how     OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be     considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning     the attack complexity high. (CVE-2025-26465)

  - A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity     expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat     can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could     lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the     environment and library usage. (CVE-2024-8176)

  - A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is     allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client     key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled     increase in memory consumption on the server side. Consequently, the server may become unavailable,     resulting in a denial of service attack. (CVE-2025-26466)
