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.
A DOM Clobbering vulnerability was found in Webpack via AutoPublicPathRuntimeModule. DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script through seemingly benign HTML markups in the webpage, for example, 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.
Отчет
The severity of this issue is classified as moderate rather than important due to the specific conditions required for exploitation. DOM Clobbering, while serious, can only be leveraged in environments where an attacker has the ability to inject unsanitized HTML attributes (e.g., name or id) into a web page. This limits the attack surface to applications that improperly sanitize user input and rely on Webpack-generated files. Furthermore, the exploitation depends on existing vulnerabilities in the sanitization process, rather than the direct execution of arbitrary scripts. As a result, while the issue can lead to XSS, its impact is constrained by the contextual requirement of HTML injection, lowering its overall severity compared to more direct XSS vectors.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
