Descriptions
Shibboleth XMLTooling before 3.2.4, as used in OpenSAML and Shibboleth Service Provider, allows SSRF via a crafted KeyInfo element. (This is fixed in, for example, Shibboleth Service Provider 3.4.1.3 on Windows.)
Jurien de Jong discovered that XMLTooling did not properly handle certain KeyInfo element content within an XML signature. An attacker could possibly use this issue to achieve server-side request forgery.
