Webpack is a module bundler. Its main purpose is to bundle JavaScript files
for usage in a browser, yet it is also capable of transforming, bundling,
or packaging just about any resource or asset. The webpack developers have
discovered a DOM Clobbering vulnerability in Webpack’s
AutoPublicPathRuntimeModule
. The DOM Clobbering gadget in the module can
lead to cross-site scripting (XSS) in web pages where scriptless
attacker-controlled HTML elements (e.g., an img
tag with an unsanitized
name
attribute) are present. Real-world exploitation of this gadget has
been observed in the Canvas LMS which allows a XSS attack to happen through
a javascript code compiled by Webpack (the vulnerable part is from
Webpack). DOM Clobbering is a type of code-reuse attack where the attacker
first embeds a piece of non-script, seemingly benign HTML markups in the
webpage (e.g. through a post or comment) and leverages the gadgets (pieces
of js code) living in the existing javascript code to transform it into
executable code. This vulnerability can lead to cross-site scripting (XSS)
on websites that include Webpack-generated files and allow users to inject
certain scriptless HTML tags with improperly sanitized name or id
attributes. This issue has been addressed in release version 5.94.0. All
users are advised to upgrade. There are no known workarounds for this
issue.
