The version of IBM Cognos Analytics installed on the remote host is prior to 11.2.4 FP4 or 12.0.4. It is, therefore, affected by multiple vulnerabilities as referenced in the 7173592 advisory.

  - An arbitrary file upload vulnerability in formidable v3.1.4 allows attackers to execute arbitrary code via     a crafted filename. NOTE: some third parties dispute this issue because the product has common use cases     in which uploading arbitrary files is the desired behavior. Also, there are configuration options in all     versions that can change the default behavior of how files are handled. Strapi does not consider this to     be a valid vulnerability. (CVE-2022-29622)

  - Node.js IP package could allow a remote attacker to execute arbitrary code on the system, caused by a     server-side request forgery flaw in the ip.isPublic() function. By sending a specially crafted request     using a hexadecimal representation of a private IP address, an attacker could exploit this vulnerability     to execute arbitrary code on the system and obtain sensitive information. (CVE-2023-42282)   
  - Multiple vendors are vulnerable to a denial of service, caused by a flaw in handling multiplexed streams     in the HTTP/2 protocol. By sending numerous HTTP/2 requests and RST_STREAM frames over multiple streams, a     remote attacker could exploit this vulnerability to cause a denial of service due to server resource     consumption. (CVE-2023-44487)

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

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

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-4949 advisory.

  - In Eclipse Jetty version 9.2.26 and older, 9.3.25 and older, and 9.4.15 and older, the server is     vulnerable to XSS conditions if a remote client USES a specially formatted URL against the DefaultServlet     or ResourceHandler that is configured for showing a Listing of directory contents. (CVE-2019-10241)

  - In Eclipse Jetty version 7.x, 8.x, 9.2.27 and older, 9.3.26 and older, and 9.4.16 and older, the server     running on any OS and Jetty version combination will reveal the configured fully qualified directory base     resource location on the output of the 404 error for not finding a Context that matches the requested     path. The default server behavior on jetty-distribution and jetty-home will include at the end of the     Handler tree a DefaultHandler, which is responsible for reporting this 404 error, it presents the various     configured contexts as HTML for users to click through to. This produced HTML includes output that     contains the configured fully qualified directory base resource location for each context.
    (CVE-2019-10247)

  - In Eclipse Jetty versions 1.0 thru 9.4.32.v20200930, 10.0.0.alpha1 thru 10.0.0.beta2, and 11.0.0.alpha1     thru 11.0.0.beta2O, on Unix like systems, the system's temporary directory is shared between all users on     that system.

If any code is ever executed out of     this temporary directory, this can lead to a local privilege escalation vulnerability. (CVE-2020-27216)

  - In Eclipse Jetty 9.4.6.v20170531 to 9.4.36.v20210114 (inclusive), 10.0.0, and 11.0.0 when Jetty handles a     request containing multiple Accept headers with a large number of quality (i.e. q) parameters, the     server may enter a denial of service (DoS) state due to high CPU usage processing those quality values,     resulting in minutes of CPU time exhausted processing those quality values. (CVE-2020-27223)

  - The td-agent-builder plugin before 2020-12-18 for Fluentd allows attackers to gain privileges because the     bin directory is writable by a user account, but a file in bin is executed as NT AUTHORITY\SYSTEM.
    (CVE-2020-28169)

  - For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, if an exception is thrown from the     SessionListener#sessionDestroyed() method, then the session ID is not invalidated in the session ID     manager.

Several vulnerabilities were discovered in jetty, a Java servlet engine and webserver. An attacker may reveal cryptographic credentials such as passwords to a local user, disclose installation paths, hijack user sessions or tamper with collocated webapps.

CVE-2017-9735

Jetty is prone to a timing channel in util/security/Password.java, which makes it easier for remote attackers to obtain access by observing elapsed times before rejection of incorrect passwords.

CVE-2018-12536

On webapps deployed using default Error Handling, when an intentionally bad query arrives that doesn't match a dynamic url-pattern, and is eventually handled by the DefaultServlet's static file serving, the bad characters can trigger a java.nio.file.InvalidPathException which includes the full path to the base resource directory that the DefaultServlet and/or webapp is using. If this InvalidPathException is then handled by the default Error Handler, the InvalidPathException message is included in the error response, revealing the full server path to the requesting system.

CVE-2019-10241

The server is vulnerable to XSS conditions if a remote client USES a specially formatted URL against the DefaultServlet or ResourceHandler that is configured for showing a Listing of directory contents.

CVE-2019-10247

The server running on any OS and Jetty version combination will reveal the configured fully qualified directory base resource location on the output of the 404 error for not finding a Context that matches the requested path. The default server behavior on jetty-distribution and jetty-home will include at the end of the Handler tree a DefaultHandler, which is responsible for reporting this 404 error, it presents the various configured contexts as HTML for users to click through to. This produced HTML includes output that contains the configured fully qualified directory base resource location for each context.

CVE-2020-27216

On Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.

This update also includes several other bug fixes and improvements.
For more information please refer to the upstream changelog file.

For Debian 9 stretch, these problems have been fixed in version 9.2.30-0+deb9u1.

We recommend that you upgrade your jetty9 packages.
