CVE-2024-37297
WooCommerce has a Cross-Site Scripting (XSS) Vulnerability in checkout & registration forms
Impact
### Impact A vulnerability introduced in WooCommerce 8.8 allows for cross-site scripting. A bad actor can manipulate a link to include malicious HTML & JavaScript content. While the content is not saved to the database, the links may be sent to victims for malicious purposes. The injected JavaScript could hijack content & data stored in the browser, including the session. The URL content is read through the Sourcebuster.js library and then inserted without proper sanitization to the classic checkout and registration forms. ### Patches ```diff diff --git a/plugins/woocommerce/client/legacy/js/frontend/order-attribution.js b/plugins/woocommerce/client/legacy/js/frontend/order-attribution.js index 79411e928e1..25eaa721c54 100644 --- a/plugins/woocommerce/client/legacy/js/frontend/order-attribution.js +++ b/plugins/woocommerce/client/legacy/js/frontend/order-attribution.js @@ -155,12 +155,16 @@ * but it's not yet supported in Safari. */ connectedCallback() { - let inputs = ''; + this.innerHTML = ''; + const inputs = new DocumentFragment(); for( const fieldName of this._fieldNames ) { - const value = stringifyFalsyInputValue( this.values[ fieldName ] ); - inputs += `<input type="hidden" name="${params.prefix}${fieldName}" value="${value}"/>`; + const input = document.createElement( 'input' ); + input.type = 'hidden'; + input.name = `${params.prefix}${fieldName}`; + input.value = stringifyFalsyInputValue( ( this.values && this.values[ fieldName ] ) || '' ); + inputs.appendChild( input ); } - this.innerHTML = inputs; + this.appendChild( inputs ); } /** ``` ### Workarounds Disabling the Order Attribution feature ### References A8C SIRT: p3btAN-2L2-p2 (internal) Public disclosure: https://developer.woocommerce.com/2024/06/10/developer-advisory-xss-vulnerability-8-8-0/
