CVE-2024-32962 · Severity: low · CVSS 3.1 · Published 2024-05-01

xml-crypto is a Node.js library used for digital signatures and encryption in XML documents, often used in authentication systems like SAML. A vulnerability in its default configuration allows attackers to bypass security checks by providing their own untrusted certificate within a malicious document. This could allow an attacker to spoof digital signatures, potentially leading to unauthorized access or the ability to submit fraudulent data that the system treats as authentic.

Technologies: [xml-crypto (npm)](https://junglewise.ai/threats/technologies/xml-crypto). Vendors: [npm](https://junglewise.ai/threats/vendors/npm).

  npm install xml-crypto@6.0.0
  ```


## Technical details

The vulnerability exists in xml-crypto versions 4.x and 5.x due to the default behavior of the getCertFromKeyInfo method. By default, the library extracts and trusts any X509Certificate found in the <KeyInfo /> element of a signed XML document, even if a specific publicCert was explicitly configured for verification. An attacker can exploit this by re-signing a document with a malicious private key and attaching the corresponding certificate to the XML. The library will prefer the attacker-supplied certificate over the trusted one, resulting in a successful signature validation of a spoofed payload. This was addressed in version 6.0.0 by disabling the implicit usage of the default certificate extraction logic.
