A session hijack risk was identified in the Shibboleth authentication plugin.

The OIDC OP plugin before 3.0.4 for Shibboleth Identity Provider allows server-side request forgery (SSRF) due to insufficient restriction of the request_uri parameter. This allows attackers to interact with arbitrary third-party HTTP services.

Shibboleth Service Provider 3.x before 3.2.2 is prone to a NULL pointer dereference flaw involving the session recovery feature. The flaw is exploitable (for a daemon crash) on systems not using this feature if a crafted cookie is supplied.

Shibboleth Service Provider before 3.2.1 allows content injection because template generation uses attacker-controlled parameters.

It was found in Moodle before version 3.10.1, 3.9.4, 3.8.7 and 3.5.16 that it was possible for site administrators to execute arbitrary PHP scripts via a PHP include used during Shibboleth authentication.

Shibboleth Identify Provider 3.x before 3.4.6 has a denial of service flaw. A remote unauthenticated attacker can cause a login flow to trigger Java heap exhaustion due to the creation of objects in the Java Servlet container session.

Shibboleth Service Provider (SP) 3.x before 3.1.0 shipped a spec file that calls chown on files in a directory controlled by the service user (the shibd account) after installation. This allows the user to escalate to root by pointing symlinks to files such as /etc/shadow.

The keygen.sh script in Shibboleth SP 2.0 (located in /usr/local/etc/shibboleth by default) uses OpenSSL to create a DES private key which is placed in sp-key.pm. It relies on the root umask (default 22) instead of chmoding the resulting file itself, so the generated private key is world readable by default.

The XMLTooling library all versions prior to V3.0.4, provided with the OpenSAML and Shibboleth Service Provider software, contains an XML parsing class. Invalid data in the XML declaration causes an exception of a type that was not handled properly in the parser class and propagates an unexpected exception type.

The (1) HttpResource and (2) FileBackedHttpResource implementations in Shibboleth Identity Provider (IdP) before 2.4.1 and OpenSAML Java 2.6.2 do not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Blackboard Learn (Since at least 17th of October 2017) has allowed Unvalidated Redirects on any signed-in user through its endpoints for handling Shibboleth logins, as demonstrated by a webapps/bb-auth-provider-shibboleth-BBLEARN/execute/shibbolethLogin?returnUrl= URI.

Shibboleth XMLTooling-C before 1.6.4, as used in Shibboleth Service Provider before 2.6.1.4 on Windows and other products, mishandles digital signatures of user data, which allows remote attackers to obtain sensitive information or conduct impersonation attacks via crafted XML data. NOTE: this issue exists because of an incomplete fix for CVE-2018-0486.

Shibboleth XMLTooling-C before 1.6.3, as used in Shibboleth Service Provider before 2.6.0 on Windows and other products, mishandles digital signatures of user attribute data, which allows remote attackers to obtain sensitive information or conduct impersonation attacks via a crafted DTD.

shibsp/metadata/DynamicMetadataProvider.cpp in the Dynamic MetadataProvider plugin in Shibboleth Service Provider before 2.6.1 fails to properly configure itself with the MetadataFilter plugins and does not perform critical security checks such as signature verification, enforcement of validity periods, and other checks specific to deployments, aka SSPCPP-763.

The shibboleth_login_form function in shibboleth.php in the Shibboleth plugin before 1.8 for WordPress is prone to an XSS vulnerability due to improper use of add_query_arg().

Cross-site scripting (XSS) vulnerability in the Shibboleth authentication module 6.x-4.x before 6.x-4.2 and 7.x-4.x before 7.x-4.2 for Drupal allows remote authenticated users with the "Administer blocks" permission to inject arbitrary web script or HTML via unspecified vectors related to a login link.

XMLTooling-C before 1.5.5, as used in OpenSAML-C and Shibboleth Service Provider (SP), does not properly handle integer conversion exceptions, which allows remote attackers to cause a denial of service (crash) via schema-invalid XML data.

xmltooling_project

The PKIX trust engines in Shibboleth Identity Provider before 2.4.4 and OpenSAML Java (OpenSAML-J) before 2.6.5 trust candidate X.509 credentials when no trusted names are available for the entityID, which allows remote attackers to impersonate an entity via a certificate issued by a shibmd:KeyAuthority trust anchor.

Cross-site request forgery (CSRF) vulnerability in auth/shibboleth/logout.php in Moodle through 2.5.9, 2.6.x before 2.6.7, 2.7.x before 2.7.4, and 2.8.x before 2.8.2 allows remote attackers to hijack the authentication of arbitrary users for requests that trigger a logout.

Cross-site request forgery (CSRF) vulnerability in the Shibboleth Authentication module before 6.x-4.1 and 7.x-4.x before 7.x-4.1 for Drupal allows remote attackers to hijack the authentication of administrators for requests that delete user role matching rules via unspecified vectors.
