Vulnerability in XML Digital Signature Library for Node.js
CVE-2025-29775
What is CVE-2025-29775?
CVE-2025-29775 is a security vulnerability found in the XML Digital Signature Library known as xml-crypto, which is utilized in Node.js applications. This library is essential for handling XML digital signatures and encryption, critical for maintaining the integrity and authenticity of XML documents within various systems. The vulnerability specifically allows attackers to bypass authentication and authorization checks, enabling the manipulation of signed XML messages. This can lead to serious security breaches, as it may permit unauthorized changes to identity or access control settings, threatening the overall integrity of affected systems.
Technical Details
The vulnerability affects versions of the xml-crypto library prior to 6.0.1, 3.2.1, and 2.1.6. It allows attackers to modify valid signed XML messages in such a manner that they still satisfy signature verification processes. By exploiting this flaw, adversaries can escalate privileges or impersonate other users, manipulating crucial components of web service interactions that rely on XML document verification. To mitigate the risk associated with CVE-2025-29775, users are advised to upgrade to the respective patched versions addressing this vulnerability promptly.
Potential impact of CVE-2025-29775
-
Privilege Escalation: Attackers can gain unauthorized elevated privileges, which could lead to increased access to sensitive data and functionalities within the application, posing significant risks to organizational security.
-
User Impersonation: The vulnerability enables malicious users to impersonate legitimate users, facilitating unauthorized actions and potentially leading to data breaches and abuse of system resources.
-
Integrity Compromise: Systems relying on xml-crypto for authentication and authorization may face integrity issues, as attackers can alter the content of signed XML documents without detection, undermining trust in the data processed by the application.
