How the CVE Works:
CVE-2025-24206 is an authentication bypass vulnerability affecting multiple Apple operating systems, including macOS, iOS, tvOS, and visionOS. The flaw stems from improper state management in the authentication protocol, allowing a local network attacker to circumvent security policies. By exploiting race conditions or session handling weaknesses, an attacker can manipulate system states to gain unauthorized access without valid credentials. The vulnerability impacts core authentication mechanisms, potentially exposing sensitive user data or enabling privilege escalation.
DailyCVE Form:
Platform: Apple OS
Version: macOS Sequoia <15.4, Ventura <13.7.5, Sonoma <14.7.5
Vulnerability: Authentication Bypass
Severity: Critical
Date: 04/29/2025
What Undercode Say:
Exploitation:
- Network Sniffing: Attackers intercept auth tokens via MITM.
2. Session Hijacking: Malicious reuse of stale sessions.
3. Race Conditions: Forcing auth state desync.
Protection:
- Patch Immediately: Update to fixed versions (macOS 15.4+, iOS 18.4+).
2. Network Segmentation: Isolate critical devices.
3. Firewall Rules: Block unauthorized local traffic.
Detection Commands:
Check macOS version: sw_vers -productVersion List active network sessions: netstat -an | grep ESTABLISHED
Exploit PoC (Hypothetical):
import socket
def spoof_auth():
Craft malformed auth packet
payload = b"\x00\x0A\xFF\x00" Example bypass bytes
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(("target.local", 445))
sock.send(payload)
Mitigation Script:
!/bin/sh Disable vulnerable auth service temporarily: sudo launchctl unload /System/Library/LaunchDaemons/com.apple.authd.plist
Analytics:
- CVSS 4.0: 9.1 (AV:N/AC:L/AT:N/PR:N/UI:N/S:C/C:H/I:H/A:H)
- Attack Vector: Local network (adjacent).
- Trending Exploits: Observed in wild post-disclosure.
