This commit adds a module for the npm component
"marked" which exploits a Regular Expression
Denial of Service (ReDoS) vulnerability in the
"heading" regular expression. Also included
is the documentation markdown for this module.
This module triggers a Denial of Service vulnerability in the Sync Breeze Enterprise HTTP server. Vulnerable version of the product can be downloaded here (http://www.syncbreeze.com/setups/syncbreezeent_setup_v10.6.24.exe). After installing the software web server should be enabled via Options->Server->Enable web server on port. Module triggers a user space write access violation on syncbrs.exe memory region. Number of requests that will crash the server changes between 200-1000 depending on the OS version and system memory.
A few things were changed as per the PR comments:
1) The module title was reworded
2) The module description was multi-lined
3) Negative logic was rewritten to use 'unless'
4) Strings which did not require interpolation were rewritten
5) Documentation markdown was added.
"ua-parser-js" is an npm module for parsing browser
user-agent strings. Vulnerable version of this module
have a problematic regular expression that can be exploited
to cause the entire application processing thread to "pause"
as it tries to apply the regular expression to the input.
This is problematic for single-threaded application environments
such as nodejs. The end result is a denial of service
condition for vulnerable applications, where no further
requests can be processed.
This module verifies if ws is vulnerable
to DoS by sending a request to the server
containing a specific header value.
ws is a npm module which handles websockets.
