CVE-2025-43187

Vulnerability: CVE-2025-43187

What the vulnerability is

CVE-2025-43187 is a code execution vulnerability in macOS that arises when running an hdiutil command. The issue was addressed by removing the vulnerable code, indicating a flaw in how the system handled certain disk image operations. The official description states that running an hdiutil command may unexpectedly execute arbitrary code, suggesting a lack of proper input validation or path handling in the affected component [1][2][3].

How it is exploited

An attacker could exploit this vulnerability by crafting a malicious disk image or a specially crafted hdiutil command that, when processed, triggers arbitrary code execution. The attack vector likely involves tricking a user into running the malicious command, either through social engineering or by embedding it in a seemingly benign file. No authentication is required beyond the user's ability to execute hdiutil, which is a standard macOS tool [4].

Impact

Successful exploitation allows an attacker to execute arbitrary code with the privileges of the user running the command. This could lead to full compromise of the user's session, including data theft, installation of malware, or further escalation of privileges. The vulnerability is rated High with a CVSS v3 score of 7.8, reflecting the significant risk of code execution [1][2][3].

Mitigation

Apple has released patches for this vulnerability in macOS Sequoia 15.6, macOS Sonoma 14.7.7, and macOS Ventura 13.7.7, all released on July 29, 2025. Users are strongly advised to update their systems to the latest available versions. No workarounds are mentioned; the fix involves removing the vulnerable code entirely [1][2][3][4].
