How the CVE Works:
CVE-2025-24271 is a critical vulnerability in Apple’s macOS and related operating systems that allows an unauthenticated attacker on the same network to send unauthorized AirPlay commands to a logged-in Mac. The flaw stems from insufficient access restrictions in the AirPlay protocol implementation, enabling remote command execution without requiring device pairing. Attackers exploit this by crafting malicious AirPlay packets, bypassing authentication checks, and gaining control over media playback, screen mirroring, or other AirPlay functionalities.
DailyCVE Form:
Platform: macOS / Apple OS
Version: Sequoia 15.4, Ventura 13.7.5, Sonoma 14.7.5
Vulnerability: Unauthenticated AirPlay Execution
Severity: Critical
Date: 04/29/2025
What Undercode Say:
Exploitation:
- Network Sniffing: Attackers scan for vulnerable Macs on the same network.
- Craft Malicious Packets: Use tools like `scapy` to forge AirPlay requests:
from scapy.all import send(IP(dst="target_ip")/UDP(dport=7000)/Raw(load="malicious_airplay_payload"))
- Trigger Unauthorized Actions: Execute commands like screen takeover or audio hijacking.
Detection:
- Log Analysis: Check `system.log` for unexpected AirPlay requests:
grep -i "airplay" /var/log/system.log
- Network Monitoring: Detect rogue AirPlay traffic with
tcpdump:tcpdump -i en0 port 7000 -v
Mitigation:
- Patch Immediately: Update to macOS 15.4, 13.7.5, or 14.7.5.
2. Network Segmentation: Isolate Macs from untrusted networks.
3. Firewall Rules: Block unauthorized AirPlay traffic:
sudo pfctl -e -f /etc/pf.conf
Add to `/etc/pf.conf`:
block in proto udp from any to any port 7000
Proof of Concept (PoC):
A minimal PoC to test vulnerability (ethical use only):
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.sendto(b"malicious_airplay_cmd", ("target_ip", 7000))
Post-Exploitation Analysis:
- Forensics: Examine `/Library/Preferences/com.apple.AirPlay.plist` for tampering.
- Recovery: Disable AirPlay via System Preferences > Sharing > AirPlay.
