This repository provides a full exploit chain for CVE-2018-20555, a vulnerability in the 'Social Network Tabs' WordPress plugin by Design Chemical. The vulnerability causes Twitter API credentials (consumer_key, consumer_secret, access_token, access_token_secret) to be exposed in the HTML/JavaScript of pages using the plugin. The repository includes: - A Scrapy-based Python crawler (TwitterApiKeysSearchEngine) that automates the discovery of vulnerable sites by searching Google, Bing, and Baidu for URLs containing the vulnerable plugin endpoint. The spider parses the URLs to extract Twitter API keys directly from the query parameters. - A large CSV file (twitter_keys.csv) containing hundreds of discovered Twitter API credentials from real-world sites. - A Python script (test_twitter_api_keys.py) that can use these credentials to authenticate to the Twitter API and perform actions such as testing account access, liking tweets, and retweeting. This script demonstrates the impact of the vulnerability by showing that attackers can take over Twitter accounts, including verified and high-follower accounts, if their credentials are leaked. - A text file (vulnerable_accounts.txt) listing the Twitter accounts confirmed to be vulnerable. The exploit is operational and automates both the discovery and exploitation phases. The main attack vector is network-based, targeting publicly accessible websites. The repository is well-structured, with clear separation between the crawler, exploitation scripts, and data files. No fake or destructive code is present; the exploit is a real-world, impactful attack chain.
