"The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2023-6570 advisory.

  - When using the RemoteIpFilter with requests received from a reverse proxy via HTTP that include the
    X-Forwarded-Proto header set to https, session cookies created by Apache Tomcat 11.0.0-M1 to 11.0.0.-M2,
    10.1.0-M1 to 10.1.5, 9.0.0-M1 to 9.0.71 and 8.5.0 to 8.5.85 did not include the secure attribute. This
    could result in the user agent transmitting the session cookie over an insecure channel. (CVE-2023-28708)

  - The fix for CVE-2023-24998 was incomplete for Apache Tomcat 11.0.0-M2 to 11.0.0-M4, 10.1.5 to 10.1.7,
    9.0.71 to 9.0.73 and 8.5.85 to 8.5.87. If non-default HTTP connector settings were used such that the
    maxParameterCount could be reached using query string parameters and a request was submitted that supplied
    exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be
    bypassed with the potential for a denial of service to occur. (CVE-2023-28709)

  - Apache Commons FileUpload before 1.5 does not limit the number of request parts to be processed resulting
    in the possibility of an attacker triggering a DoS with a malicious upload or series of uploads. Note
    that, like all of the file upload limits, the new configuration option (FileUploadBase#setFileCountMax) is
    not enabled by default and must be explicitly configured. (CVE-2023-24998)

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