All the vulnerabilities related to the version 10.3.0 of the package
cookie accepts cookie name, path, and domain with out of bounds characters
The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. For example, serialize("userName=<script>alert('XSS3')</script>; Max-Age=2592000; a", value) would result in "userName=<script>alert('XSS3')</script>; Max-Age=2592000; a=test", setting userName cookie to <script> and ignoring value.
A similar escape can be used for path and domain, which could be abused to alter other fields of the cookie.
Upgrade to 0.7.0, which updates the validation for name, path, and domain.
Avoid passing untrusted or arbitrary values for these fields, ensure they are set by the application instead of user input.
tar-fs Vulnerable to Link Following and Path Traversal via Extracting a Crafted tar File
An Improper Link Resolution Before File Access ("Link Following") and Improper Limitation of a Pathname to a Restricted Directory ("Path Traversal"). This vulnerability occurs when extracting a maliciously crafted tar file, which can result in unauthorized file writes or overwrites outside the intended extraction directory. The issue is associated with index.js in the tar-fs package.
This issue affects tar-fs: from 0.0.0 before 1.16.4, from 2.0.0 before 2.1.2, from 3.0.0 before 3.0.7.
tar-fs can extract outside the specified dir with a specific tarball
v3.0.8, v2.1.2, v1.16.4 and below
Has been patched in 3.0.9, 2.1.3, and 1.16.5
You can use the ignore option to ignore non files/directories.
ignore (_, header) {
// pass files & directories, ignore e.g. symlinks
return header.type !== 'file' && header.type !== 'directory'
}
Thank you Caleb Brown from Google Open Source Security Team for reporting this in detail.
tar-fs has a symlink validation bypass if destination directory is predictable with a specific tarball
v3.1.0, v2.1.3, v1.16.5 and below
Has been patched in 3.1.1, 2.1.4, and 1.16.6
You can use the ignore option to ignore non files/directories.
ignore (_, header) {
// pass files & directories, ignore e.g. symlinks
return header.type !== 'file' && header.type !== 'directory'
}
