A malicious attacker could cause threads to hold up forever in the EJB server by writing a sequence of bytes corresponding to the expected messages of a successful EJB client request, but omitting the ACK messages, or just tamper with jboss-remoting code, deleting the lines that send the ACK message from the EJB client code resulting in a denial of service. The highest threat from this vulnerability is to system availability.","published":"2021-06-02T14:15:09.393Z","modified":"2026-07-08T20:28:56.869100Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.jboss.remoting:jboss-remoting","fixedVersion":"5.0.20.Final"}],"fix":null,"references":[{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1905796"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T20:28:56.869100Z"}}
