Vim is a highly configurable text editor built to enable efficient text editing. It is commonly used by software developers, system administrators, and anyone who needs to edit text in a command-line interface. Viminfo files, associated with Vim, are used to store command history, search history, and other interactive session-related data. These files can inadvertently disclose sensitive data if improperly exposed or accessed. Handling text editing tasks efficiently, Vim is an essential tool in programming environments and large development projects.
The vulnerability associated with Vim, specifically File Disclosure through Viminfo files, arises when these files are accessible from an external source. The Viminfo files may contain sensitive information such as command history and recently opened files, which pose a risk if exposed. This vulnerability is significant in environments where sensitive data processing occurs, and exposure could lead to information leakage. Persistent exposure of these files might provide attackers with insights into the system operation and the user’s activity.
Vulnerability details regarding Vim’s File Disclosure revolve around the unsecured access path to Viminfo files, typically requested via a GET method. These files being served without adequate permissions expose them both accidentally and deliberately. The request path, such as getting from ‘{{BaseURL}}/.viminfo’, can expose the file contents if proper server configuration and file permissions are not enforced. Furthermore, enabling configuration checks that look for specific words like 'Viminfo version' in the body response or identifying MIME types can help in detecting such disclosures.
When exploited, this vulnerability can lead to several detrimental effects. Attackers may gain unauthorized access to system command histories, exposing potentially sensitive operational data. This can include access to recently opened documents, file paths, or other personal command line entries. Additionally, improperly disclosed data could be leveraged for reconnaissance, assisting adversaries in launching more effective future attacks. Beyond immediate data leaks, persistent exposure of such files risks escalating to more severe breaches.
