"The version of hsqldb installed on the remote host is prior to 1.8.1.3-1.13. It is, therefore, affected by a
vulnerability as referenced in the ALAS-2023-1666 advisory.

  - Those using java.sql.Statement or java.sql.PreparedStatement in hsqldb (HyperSQL DataBase) to process
    untrusted input may be vulnerable to a remote code execution attack. By default it is allowed to call any
    static method of any Java class in the classpath resulting in code execution. The issue can be prevented
    by updating to 2.7.1 or by setting the system property hsqldb.method_class_names to classes which are
    allowed to be called. For example, System.setProperty(hsqldb.method_class_names, abc) or Java argument
    -Dhsqldb.method_class_names=abc can be used. From version 2.7.1 all classes by default are not
    accessible except those in java.lang.Math and need to be manually enabled. (CVE-2022-41853)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
