Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Authentication bypass in sshd-core in Apache MINA SSHD versions 2.0.0 to 2.19.0 and 3.0.0-M1 to 3.0.0-M5     for a certain (presumed rare) way to implement an SSH server. Apache MINA SSHD is a Java library for     client- and server-side SSH. In the server part of the library, a mechanism to perform asynchronous     authentication exists. A server implemented with Apache MINA SSHD must contain explicit code to make use     of this feature. The implementation of this feature was flawed and could potentially lead to skipping     checking the signature in public-key or hostbased authentication, or returning a wrong result. Users are     recommended to upgrade to Apache MINA SSHD 2.20.0 or 3.0.0-M6, which fix the logic error and which     additionally forbid the use of this asynchronous authentication mechanism with the public-key or     hostbased authentication schemes: if used, the SSH session will be closed and the server will log an entry     indicating that asynchronous authentication may be used only with password or keyboard-interactive     authentication. (CVE-2026-77185)

Note that Nessus relies on the presence of the package as reported by the vendor.
