Title source: llmExploitation Summary
EIP tracks 2 public exploits for CVE-2025-29775. PoCs published by twypsy, ethicalPap.
AI-analyzed exploit summary The repository contains functional exploit code for CVE-2025-29775, demonstrating SAML response forgery via two attack vectors (v1 and v2). The PoC modifies SAML assertions and digests to bypass authentication, leveraging parser differentials in xml-crypto and Node.js libraries.
Description
xml-crypto is an XML digital signature and encryption library for Node.js. An attacker may be able to exploit a vulnerability in versions prior to 6.0.1, 3.2.1, and 2.1.6 to bypass authentication or authorization mechanisms in systems that rely on xml-crypto for verifying signed XML documents. The vulnerability allows an attacker to modify a valid signed XML message in a way that still passes signature verification checks. For example, it could be used to alter critical identity or access control attributes, enabling an attacker to escalate privileges or impersonate another user. Users of versions 6.0.0 and prior should upgrade to version 6.0.1 to receive a fix. Those who are still using v2.x or v3.x should upgrade to patched versions 2.1.6 or 3.2.1, respectively.

This repository contains a functional PoC for CVE-2025-29775, demonstrating a SAML signature verification bypass via XML comment injection in the DigestValue element. The exploit modifies a SAML response to elevate privileges by changing the NameID to 'admin' while preserving the original signature validity.
