"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0163 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-24998:
    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-2023-28708:
    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 notinclude the secure attribute. This
    could result in the user agenttransmitting the session cookie over an insecure channel.

    CVE-2023-28709:
    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
    maxParameterCountcould be reached using query string parameters and a request was submitted that
    supplied exactly maxParameterCount parametersin the query string, the limit for uploaded request parts
    could bebypassed with the potential for a denial of service to occur.

    CVE-2023-46589:
    Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M10, from
    10.1.0-M1 through 10.1.15, from 9.0.0-M1 through 9.0.82 and from 8.5.0 through 8.5.95 did not correctly
    parse HTTP trailer headers. A trailer header that exceeded the header size limit could cause Tomcat to
    treat a single request as multiple requests leading to the possibility of request  smuggling when behind a
    reverse proxy. Users are recommended to upgrade to version 11.0.0-M11onwards, 10.1.16 onwards, 9.0.83
    onwards or 8.5.96 onwards, which fix the issue.

    CVE-2023-41080:
    URL Redirection to Untrusted Site ('Open Redirect') vulnerability in FORM authentication feature Apache
    Tomcat.This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through
    10.0.12, from 9.0.0-M1 through 9.0.79 and from 8.5.0 through 8.5.92. The vulnerability is limited to the
    ROOT (default) web application.

    CVE-2023-42794:
    Incomplete Cleanup vulnerability in Apache Tomcat. The internal fork of Commons FileUpload packaged with
    Apache Tomcat 9.0.70 through 9.0.80 and 8.5.85 through 8.5.93 included an unreleased, in progress
    refactoring that exposed a potential denial of service on Windows if a web application opened a stream for
    an uploaded file but failed to close the stream. The file would never be deleted from disk creating the
    possibility of an eventual denial of service due to the disk being full. Users are recommended to upgrade
    to version 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.

    CVE-2023-42795:
    Incomplete Cleanup vulnerability in Apache Tomcat.When recycling various internal objects in Apache Tomcat
    from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.80 and from
    8.5.0 through 8.5.93, an error could cause Tomcat to skip some parts of the recycling process leading to
    information leaking from the current request/response to the next. Users are recommended to upgrade to
    version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.

    CVE-2023-45648:
    Improper Input Validation vulnerability in Apache Tomcat.Tomcatfrom 11.0.0-M1 through 11.0.0-M11, from
    10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly
    parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a
    single request as multiple requests leading to the possibility of request smuggling when behind a reverse
    proxy. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or
    8.5.94 onwards, which fix the issue.

    CVE-2024-23672:
    Denial of Service via incomplete cleanup vulnerability in Apache Tomcat. It was possible for WebSocket
    clients to keep WebSocket connections open leading to increased resource consumption.This issue affects
    Apache Tomcat: from 11.0.0-M1 through 11.0.0-M16, from 10.1.0-M1 through 10.1.18, from 9.0.0-M1 through
    9.0.85, from 8.5.0 through 8.5.98. Users are recommended to upgrade to version 11.0.0-M17, 10.1.19, 9.0.86
    or 8.5.99 which fix the issue.

    CVE-2024-24549:
    Denial of Service due to improper input validation vulnerability for HTTP/2 requests in Apache Tomcat.
    When processing an HTTP/2 request, if the request exceeded any of the configured limits for headers, the
    associated HTTP/2 stream was not reset until after all of the headers had been processed.This issue
    affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M16, from 10.1.0-M1 through 10.1.18, from 9.0.0-M1
    through 9.0.85, from 8.5.0 through 8.5.98. Users are recommended to upgrade to version 11.0.0-M17,
    10.1.19, 9.0.86 or 8.5.99 which fix the issue.

    CVE-2024-34750:
    Improper Handling of Exceptional Conditions, Uncontrolled Resource Consumption vulnerability in Apache
    Tomcat. When processing an HTTP/2 stream, Tomcat did not handle some cases of excessive HTTP headers
    correctly. This led to a miscounting of active HTTP/2 streams which in turn led to the use of an incorrect
    infinite timeout which allowed connections to remain open which should have been closed.
    This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M20, from 10.1.0-M1 through 10.1.24, from
    9.0.0-M1 through 9.0.89.
    Users are recommended to upgrade to version 11.0.0-M21, 10.1.25 or 9.0.90, which fixes the issue.
