Background
libxml-security-java is a library used for XML digital signatures and encryption. It provides functionality for creating, validating, and manipulating XML signatures. The library is widely used in Java applications that require secure XML processing. However, a vulnerability has been discovered in the library that could allow an attacker to spoof XML signatures by exploiting weak canonicalization algorithm parameters.
Vulnerability Detail
The vulnerability in libxml-security-java arises from the incorrect validation of CanonicalizationMethod parameters in Apache Santuario XML Security for Java. By specifying a weak canonicalization algorithm, an attacker can manipulate XML signatures and potentially bypass security measures. This could lead to various attacks, such as tampering with signed XML documents or impersonating trusted entities.
