XML signatures are a method used to ensure the integrity and authenticity of XML documents. However, if XML signatures are not validated securely, it can lead to potential vulnerabilities.

Why is this an issue? How can I fix it? More Info

Before Java 17, XML Digital Signature API does not apply restrictions on XML signature validation unless the application runs with a security manager, which is rare.

What is the potential impact

By not enforcing secure validation, the XML Digital Signature API is more susceptible to attacks such as signature spoofing and injections.

Increased Vulnerability to Signature Spoofing

By disabling secure validation, the application becomes more susceptible to signature spoofing attacks. Attackers can potentially manipulate the XML signature in a way that bypasses the validation process, allowing them to forge or tamper with the signature. This can lead to the acceptance of invalid or maliciously modified signatures, compromising the integrity and authenticity of the XML documents.

Risk of Injection Attacks

Disabling secure validation can expose the application to injection attacks. Attackers can inject malicious code or entities into the XML document, taking advantage of the weakened validation process. In some cases, it can also expose the application to denial-of-service attacks. Attackers can exploit vulnerabilities in the validation process to cause excessive resource consumption or system crashes, leading to service unavailability or disruption.
