Cross-site scripting (XSS) vulnerability in UiV2Public.index in Internet2 Grouper 2.2 and 2.3 allows remote attackers to inject arbitrary web script or HTML via the code parameter.

The (1) BasicParserPool, (2) StaticBasicParserPool, (3) XML Decrypter, and (4) SAML Decrypter in Shibboleth OpenSAML-Java before 2.6.1 set the expandEntityReferences property to true, which allows remote attackers to conduct XML external entity (XXE) attacks via a crafted XML DOCTYPE declaration.

Multiple cross-site scripting (XSS) vulnerabilities in the Identity Provider (IdP) 1.3.x before 1.3.4 and 2.x before 2.1.5, and the Service Provider 1.3.x before 1.3.5 and 2.x before 2.3, in Internet2 Middleware Initiative Shibboleth allow remote attackers to inject arbitrary web script or HTML via URLs that are encountered in redirections, and appear in automatically generated forms.

Internet2 Shibboleth Service Provider software 1.3.x before 1.3.3 and 2.x before 2.2.1, when using PKIX trust validation, does not properly handle a '\0' character in the subject or subjectAltName fields of a certificate, which allows remote man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

OpenSAML 2.x before 2.2.1 and XMLTooling 1.x before 1.2.1, as used by Internet2 Shibboleth Service Provider 2.x before 2.2.1, do not follow the KeyDescriptor element's Use attribute, which allows remote attackers to use a certificate for both signing and encryption when it is designated for just one purpose, potentially weakening the intended security application of the certificate.

Buffer overflow in OpenSAML before 1.1.3 as used in Internet2 Shibboleth Service Provider software 1.3.x before 1.3.4, and XMLTooling before 1.2.2 as used in Internet2 Shibboleth Service Provider software 2.x before 2.2.1, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a malformed encoded URL.
