What is the "Github Takeover Detection?"

The "Github Takeover Detection" module is designed to detect potential takeover vulnerabilities on GitHub. It targets misconfigurations that could allow an attacker to take control of a GitHub repository or GitHub Pages site. This module has a high severity level, indicating the potential impact of a successful takeover.

This module was authored by pdteam and th3r4id.


A successful takeover of a GitHub repository or GitHub Pages site can have serious consequences. It could allow an attacker to modify the code, steal sensitive information, or deface the site, depending on the level of access gained. It is crucial to address any detected vulnerabilities promptly to prevent unauthorized access and maintain the integrity of the affected GitHub resources.

How does the module work?

The "Github Takeover Detection" module works by performing specific checks and matching conditions to identify potential takeover vulnerabilities. It uses a combination of DSL (Domain Specific Language) and word-based matchers to analyze the response received from the target.

One of the matching conditions used by this module is to ensure that the host is not an IP address. This helps filter out false positives and focus on actual GitHub resources.

Another matching condition checks for specific error messages in the response, such as "There isn't a GitHub Pages site here" or "For root URLs (like you must provide an index.html file." These messages indicate potential misconfigurations that could be exploited for a takeover.

Additionally, the module excludes certain hosts, such as "," "," and "," to avoid false positives caused by legitimate GitHub resources.

While the exact HTTP request templates used by the module are not provided, they are designed to gather the necessary information to perform the matching conditions and identify potential takeover vulnerabilities.

It is important to note that this module is just one test case within the Vidoc platform, which utilizes multiple modules to perform comprehensive scanning and detection of various security issues.
