CVE-2016-2141 – JGroups: Authorization bypass

https://notcve.org/view.php?id=CVE-2016-2141

It was found that JGroups did not require necessary headers for encrypt and auth protocols from new nodes joining the cluster. An attacker could use this flaw to bypass security restrictions, and use this vulnerability to send and receive messages within the cluster, leading to information disclosure, message spoofing, or further possible attacks. JGroups en versiones anteriores a 4.0 no solicita las cabeceras adecuadas para los protocolos ENCRYPT y AUTH desde los nodos uniéndose al grupo, lo que permite a atacantes remotos eludir las restricciones de seguridad y enviar y recibir mensajes dentro del grupo a través de vectores no especificados. • http://rhn.redhat.com/errata/RHSA-2016-1435.html http://rhn.redhat.com/errata/RHSA-2016-1439.html http://rhn.redhat.com/errata/RHSA-2016-2035.html http://www.securityfocus.com/bid/91481 http://www.securitytracker.com/id/1036165 https://access.redhat.com/errata/RHSA-2016:1345 https://access.redhat.com/errata/RHSA-2016:1346 https://access.redhat.com/errata/RHSA-2016:1347 https://access.redhat.com/errata/RHSA-2016:1374 https://access.redhat.com/errata/RHSA-2016:1376& •
