How the CVE Works:
The CVE-2025-XXXX vulnerability in Composio version v0.4.4 is a Server-Side Request Forgery (SSRF) issue that arises due to improper validation of user-supplied inputs in the `BROWSERTOOL_GOTO_PAGE` and `BROWSERTOOL_GET_PAGE_DETAILS` actions. An attacker can exploit this by crafting malicious requests that trick the server into making unauthorized internal requests. This allows the attacker to access sensitive files or services on the server, potentially leading to data leakage, internal network reconnaissance, or further exploitation of internal systems. The vulnerability is classified as moderate due to the potential impact on confidentiality and integrity, but it requires specific conditions to be exploited effectively.
DailyCVE Form:
Platform: Composio
Version: v0.4.4
Vulnerability: SSRF
Severity: Moderate
Date: Mar 20, 2025
What Undercode Say:
Exploitation:
1. Crafting Malicious Requests:
An attacker can send a crafted request to the `BROWSERTOOL_GOTO_PAGE` action with a URL pointing to an internal resource (e.g., file:///etc/passwd).
Example:
curl -X POST http://target.com/api/browsertool/goto_page -d '{"url": "file:///etc/passwd"}'
2. Exfiltrating Data:
Using the `BROWSERTOOL_GET_PAGE_DETAILS` action, the attacker can retrieve the contents of the internal resource.
Example:
curl -X POST http://target.com/api/browsertool/get_page_details -d '{"url": "file:///etc/passwd"}'
Protection:
1. Input Validation:
Implement strict input validation to ensure URLs are restricted to trusted domains.
Example (Python):
from urllib.parse import urlparse
def validate_url(url):
allowed_domains = [bash]
parsed_url = urlparse(url)
if parsed_url.netloc not in allowed_domains:
raise ValueError("Invalid URL")
2. Network Segmentation:
Restrict server access to internal resources using firewalls or network policies.
3. Patch Management:
Update to the latest version of Composio if a patch is available.
4. Web Application Firewall (WAF):
Deploy a WAF to detect and block SSRF attempts.
Example (ModSecurity rule):
SecRule ARGS:url "@contains file://" "id:1001,deny,status:403,msg:'SSRF Attempt'"
5. Monitoring and Logging:
Monitor and log all requests to detect suspicious activity.
Example (Linux command):
tail -f /var/log/nginx/access.log | grep "POST /api/browsertool"
6. Disable Unused Actions:
Disable or restrict access to `BROWSERTOOL_GOTO_PAGE` and `BROWSERTOOL_GET_PAGE_DETAILS` if not required.
7. Use Secure Libraries:
Replace vulnerable components with secure alternatives that enforce URL validation.
By following these steps, organizations can mitigate the risk of SSRF vulnerabilities and protect their systems from exploitation.
