Send is a Node.js module designed for efficiently streaming static files, boasting features like Range and conditional-GET support for optimized delivery. Version 0.3.0, released in April 2014, builds upon the foundation of version 0.2.0, released in January 2014, bringing key dependency updates and refinements. A notable change is the upgrade of the mime dependency from ~1.2.9 to 1.2.11, ensuring developers have access to the latest MIME type definitions for accurate file serving. The debug dependency also sees an update, moving from '*' (any version) to a specific version 0.8.0, likely for enhanced stability and predictability in debugging output. The introduction of buffer-crc32 as a dependency in version 0.3.0 suggests improved data integrity checks during file transmission. The supertest dependency's version was incremented from 0.0.1 to 0.10.0.
Both versions maintain essential features like support for fresh and range-parser modules, crucial for handling conditional requests and partial content delivery, respectively. Developers using Send can leverage these capabilities to reduce bandwidth usage and improve the user experience. The module, authored by TJ Holowaychuk, is available on GitHub under the visionmedia/send repository, offering a well-documented and community-supported solution for static file serving needs in Node.js applications. Developers should note the test framework used for development, which includes the mocha test runner and should assertion library.
All the vulnerabilities related to the version 0.3.0 of the package
Directory Traversal in send
Versions 0.8.3 and earlier of send are affected by a directory traversal vulnerability. When relying on the root option to restrict file access it may be possible for an application consumer to escape out of the restricted directory and access files in a similarly named directory.
For example, static(_dirname + '/public') would allow access to _dirname + '/public-restricted'.
Update to version 0.8.4 or later.
Root Path Disclosure in send
Versions of send prior to 0.11.2 are affected by an information leakage vulnerability which may allow an attacker to enumerate paths on the server filesystem.
Update to version 0.11.1 or later.
send vulnerable to template injection that can lead to XSS
passing untrusted user input - even after sanitizing it - to SendStream.redirect() may execute untrusted code
this issue is patched in send 0.19.0
users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist
successful exploitation of this vector requires the following:
mime Regular Expression Denial of Service when MIME lookup performed on untrusted user input
Affected versions of mime are vulnerable to regular expression denial of service when a mime lookup is performed on untrusted user input.
Update to version 2.0.3 or later.
debug Inefficient Regular Expression Complexity vulnerability
A vulnerability classified as problematic has been found in debug-js debug up to 3.0.x. This affects the function useColors of the file src/node.js. The manipulation of the argument str leads to inefficient regular expression complexity. Upgrading to version 3.1.0 is able to address this issue. The name of the patch is c38a0166c266a679c8de012d4eaccec3f944e685. It is recommended to upgrade the affected component. The identifier VDB-217665 was assigned to this vulnerability. The patch has been backported to the 2.6.x branch in version 2.6.9.
Regular Expression Denial of Service in debug
Affected versions of debug are vulnerable to regular expression denial of service when untrusted user input is passed into the o formatter.
As it takes 50,000 characters to block the event loop for 2 seconds, this issue is a low severity issue.
This was later re-introduced in version v3.2.0, and then repatched in versions 3.2.7 and 4.3.1.
Version 2.x.x: Update to version 2.6.9 or later. Version 3.1.x: Update to version 3.1.0 or later. Version 3.2.x: Update to version 3.2.7 or later. Version 4.x.x: Update to version 4.3.1 or later.
Regular Expression Denial of Service in fresh
Affected versions of fresh are vulnerable to regular expression denial of service when parsing specially crafted user input.
Update to version 0.5.2 or later.
