The vulnerability identified as CVE-2025-29775 affects the xml-crypto library, a key component used for XML digital signatures and encryption in Node.js applications. This vulnerability allows an attacker to exploit versions prior to 6.0.1, 3.2.1, and 2.1.6, enabling them to bypass authentication or authorization mechanisms. The impact is particularly severe as it permits modification of valid signed XML messages, which can pass signature verification checks. This capability could lead to unauthorized privilege escalation or impersonation of users.
The severity of this vulnerability is classified as critical, with a CVSS score of 9.3. Organizations utilizing xml-crypto should be aware that attackers may leverage this vulnerability to compromise systems significantly. The urgency for organizations to patch this vulnerability is high, as it poses a real-world risk of unauthorized access and manipulation of critical data.
Users are strongly urged to upgrade to version 6.0.1, 3.2.1, or 2.1.6 or higher to mitigate this risk. The vulnerability was disclosed on March 14, 2025, and immediate patching is essential to prevent exploitation.
Risk to organizations includes potential unauthorized access and control over sensitive systems. Organizations should prioritize patching immediately to safeguard against potential threats.
Vulnerability Details
CVE-2025-29775 is a critical vulnerability affecting xml-crypto, which facilitates XML digital signatures and encryption. This vulnerability allows attackers to modify signed XML documents, thus bypassing expected authentication and authorization checks. The vulnerability is classified under CWE-347, indicating improper authentication. With a CVSS version 4.0 score of 9.3, it represents a high level of risk due to its high potential impact on confidentiality, integrity, and availability.
Technical Analysis
The root cause of this vulnerability lies in the inability of xml-crypto to properly validate signed XML messages. Attackers can exploit this flaw through a network attack vector, requiring no privileges or user interaction. The attack complexity is low, meaning that it can be executed without advanced technical skills. The impact of this vulnerability is significant, as successful exploitation could lead to unauthorized access or modification of sensitive data.
Risk & Impact Analysis
The deployment of xml-crypto in critical systems presents a substantial risk, especially in environments where XML signatures are used for authentication and authorization. The potential for attackers to exploit this vulnerability increases the blast radius, affecting not only the integrity of the signed documents but also the trustworthiness of the entire system. Organizations must evaluate their exposure to this vulnerability and act swiftly, as the potential for exploitation is high.
