This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user.

Insufficient Session Expiration

A flaw was found in undertow

CVE-2023-1108 7.5 - High - September 14, 2023

A flaw was found in undertow. This issue makes achieving a denial of service possible due to an unexpected handshake status updated in SslConduit, where the loop never terminates.

XSS

A flaw was found in Keycloak

CVE-2023-1664 6.5 - Medium - May 26, 2023

A flaw was found in Keycloak. This flaw depends on a non-default configuration "Revalidate Client Certificate" to be enabled and the reverse proxy is not validating the certificate before Keycloak. Using this method an attacker may choose the certificate which will be validated by the server. If this happens and the KC_SPI_TRUSTSTORE_FILE_FILE variable is missing/misconfigured, any trustfile may be accepted with the logging information of "Cannot validate client certificate trust: Truststore not available". This may not impact availability as the attacker would have no access to the server, but consumer applications Integrity or Confidentiality may be impacted considering a possible access to them. Considering the environment is correctly set to use "Revalidate Client Certificate" this flaw is avoidable.

AuthZ

It was found that Picketlink as shipped with Jboss Enterprise Application Platform 7.2

CVE-2019-3873 9 - Critical - June 12, 2019

It was found that Picketlink as shipped with Jboss Enterprise Application Platform 7.2 would accept an xinclude parameter in SAMLresponse XML. An attacker could use this flaw to send a URL to achieve cross-site scripting or possibly conduct further attacks.

XSS

A vulnerability was found in keycloak before 6.0.2

CVE-2019-3875 4.8 - Medium - June 12, 2019

A vulnerability was found in keycloak before 6.0.2. The X.509 authenticator supports the verification of client certificates through the CRL, where the CRL list can be obtained from the URL provided in the certificate itself (CDP) or through the separately configured path. The CRL are often available over the network through unsecured protocols ('http' or 'ldap') and hence the caller should verify the signature and possibly the certification path. Keycloak currently doesn't validate signatures on CRL, which can result in a possibility of various attacks like man-in-the-middle.

Improper Certificate Validation

It was found that a SAMLRequest containing a script could be processed by Picketlink versions shipped in Jboss Application Platform 7.2.x and 7.1.x

CVE-2019-3872 5.4 - Medium - June 12, 2019

It was found that a SAMLRequest containing a script could be processed by Picketlink versions shipped in Jboss Application Platform 7.2.x and 7.1.x. An attacker could use this to send a malicious script to achieve cross-site scripting and obtain unauthorized information or conduct further attacks.

XSS

It was found that Keycloak's Node.js adapter before version 4.8.3 did not properly verify the web token received

CVE-2019-10157 5.5 - Medium - June 12, 2019

It was found that Keycloak's Node.js adapter before version 4.8.3 did not properly verify the web token received from the server in its backchannel logout . An attacker with local access could use this to construct a malicious web token setting an NBF parameter that could prevent user access indefinitely.

authentification

A cross-site scripting (XSS) vulnerability was found in the JBoss Management Console versions before 7.1.6.CR1, 7.1.6.GA

CVE-2018-10934 5.4 - Medium - March 27, 2019

A cross-site scripting (XSS) vulnerability was found in the JBoss Management Console versions before 7.1.6.CR1, 7.1.6.GA. Users with roles that can create objects in the application can exploit this to attack other privileged users.

XSS

An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6

CVE-2018-12022 7.5 - High - March 21, 2019

An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default Typing is enabled (either globally or for a specific property), the service has the Jodd-db jar (for database access for the Jodd framework) in the classpath, and an attacker can provide an LDAP service to access, it is possible to make the service execute a malicious payload.

Marshaling, Unmarshaling

An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6

CVE-2018-12023 7.5 - High - March 21, 2019

An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default Typing is enabled (either globally or for a specific property), the service has the Oracle JDBC jar in the classpath, and an attacker can provide an LDAP service to access, it is possible to make the service execute a malicious payload.

Marshaling, Unmarshaling

A flaw was found in Keycloak 3.4.3.Final, 4.0.0.Beta2, 4.3.0.Final

CVE-2018-14655 5.4 - Medium - November 13, 2018

A flaw was found in Keycloak 3.4.3.Final, 4.0.0.Beta2, 4.3.0.Final. When using 'response_mode=form_post' it is possible to inject arbitrary Javascript-Code via the 'state'-parameter in the authentication URL. This allows an XSS-Attack upon succesfully login.

XSS

A flaw was found in Keycloak 4.2.1.Final, 4.3.0.Final

CVE-2018-14657 8.1 - High - November 13, 2018
