Jetty is a Java based web server and servlet engine. Versions 9.4.21 through 9.4.51, 10.0.15, and 11.0.15 are vulnerable to weak authentication. If a Jetty `OpenIdAuthenticator` uses the optional nested `LoginService`, and that `LoginService` decides to revoke an already authenticated user, then the current request will still treat the user as authenticated. The authentication is then cleared from the session and subsequent requests will not be treated as authenticated. So a request on a previously authenticated session could be allowed to bypass authentication after it had been rejected by the `LoginService`. This impacts usages of the jetty-openid which have configured a nested `LoginService` and where that `LoginService` will is capable of rejecting previously authenticated users. Versions 9.4.52, 10.0.16, and 11.0.16 have a patch for this issue.

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

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

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.

The versions of Oracle Database Server installed on the remote host are affected by multiple vulnerabilities as referenced in the January 2024 CPU advisory.

  - Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected     are 19.3-19.21 and 21.3-21.12. Easily exploitable vulnerability allows low privileged attacker having     Create Session, Create Procedure privilege with network access via Oracle Net to compromise Java VM.
    Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification     access to critical data or all Java VM accessible data. (CVE-2024-20903)

  - Vulnerability in the Oracle Spatial and Graph (curl) component of Oracle Database Server. Supported     versions that are affected are 19.3-19.21, 21.3-21.12 and 23.3. Easily exploitable vulnerability allows     low privileged attacker having Authenticated User privilege with network access via HTTP to compromise     Oracle Spatial and Graph (curl). Successful attacks of this vulnerability can result in unauthorized     ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Spatial and Graph (curl).
    (CVE-2023-38545)

  - Vulnerability in the Oracle Text component of Oracle Database Server. Supported versions that are affected     are 19.3-19.21. Easily exploitable vulnerability allows high privileged attacker having DBA privilege with     network access via Oracle Net to compromise Oracle Text. Successful attacks of this vulnerability can     result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Text.
    (CVE-2022-21432)

  - Security-in-depth update for non-exploitable vulnerabilities CVE-2022-41409, CVE-2022-46337, CVE-2023-2976,     CVE-2023-4043, CVE-2023-36479, CVE-2023-40167, CVE-2023-41900, CVE-2023-42794, CVE-2023-42795,     CVE-2023-44487, CVE-2023-45648 and CVE-2023-46589,.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4210-1 advisory.

  - Eclipse Jetty provides a web server and servlet container. In versions 11.0.0 through 11.0.15, 10.0.0     through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in `MetaDataBuilder.checkSize` allows for     HTTP/2 HPACK header values to exceed their size limit. `MetaDataBuilder.java` determines if a header name     or value exceeds the size limit, and throws an exception if the limit is exceeded. However, when length is     very large and huffman is true, the multiplication by 4 in line 295 will overflow, and length will become     negative. `(_size+length)` will now be negative, and the check on line 296 will not be triggered.
    Furthermore, `MetaDataBuilder.checkSize` allows for user-entered HPACK header value sizes to be negative,     potentially leading to a very large buffer allocation later on when the user-entered size is multiplied by     2. This means that if a user provides a negative length value (or, more precisely, a length value which,     when multiplied by the 4/3 fudge factor, is negative), and this length value is a very large positive     number when multiplied by 2, then the user can cause a very large buffer to be allocated on the server.
    Users of HTTP/2 can be impacted by a remote denial of service attack. The issue has been fixed in versions     11.0.16, 10.0.16, and 9.4.53. There are no known workarounds. (CVE-2023-36478)

  - Eclipse Jetty Canonical Repository is the canonical repository for the Jetty project. Users of the     CgiServlet with a very specific command structure may have the wrong command executed. If a user sends a     request to a org.eclipse.jetty.servlets.CGI Servlet for a binary with a space in its name, the servlet     will escape the command by wrapping it in quotation marks. This wrapped command, plus an optional command     prefix, will then be executed through a call to Runtime.exec. If the original binary name provided by the     user contains a quotation mark followed by a space, the resulting command line will contain multiple     tokens instead of one. This issue was patched in version 9.4.52, 10.0.16, 11.0.16 and 12.0.0-beta2.
    (CVE-2023-36479)

  - Jetty is a Java based web server and servlet engine. Prior to versions 9.4.52, 10.0.16, 11.0.16, and     12.0.1, Jetty accepts the `+` character proceeding the content-length value in a HTTP/1 header field. This     is more permissive than allowed by the RFC and other servers routinely reject such requests with 400     responses. There is no known exploit scenario, but it is conceivable that request smuggling could result     if jetty is used in combination with a server that does not close the connection after sending such a 400     response. Versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1 contain a patch for this issue. There is no     workaround as there is no known exploit scenario. (CVE-2023-40167)

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation     can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5507 advisory.

    Multiple security vulnerabilities were found in Jetty, a Java based web server and servlet engine. The     org.eclipse.jetty.servlets.CGI class has been deprecated. It is potentially unsafe to use it. The upstream     developers of Jetty recommend to use Fast CGI instead. See also CVE-2023-36479. CVE-2023-26048 In affected     versions servlets with multipart support (e.g. annotated with `@MultipartConfig`) that call     `HttpServletRequest.getParameter()` or `HttpServletRequest.getParts()` may cause `OutOfMemoryError` when     the client sends a multipart request with a part that has a name but no filename and very large content.
    This happens even with the default settings of `fileSizeThreshold=0` which should stream the whole part     content to disk. CVE-2023-26049 Nonstandard cookie parsing in Jetty may allow an attacker to smuggle     cookies within other cookies, or otherwise perform unintended behavior by tampering with the cookie     parsing mechanism. CVE-2023-40167 Prior to this version Jetty accepted the `+` character proceeding the     content-length value in a HTTP/1 header field. This is more permissive than allowed by the RFC and other     servers routinely reject such requests with 400 responses. There is no known exploit scenario, but it is     conceivable that request smuggling could result if jetty is used in combination with a server that does     not close the connection after sending such a 400 response.

For the oldstable     distribution (bullseye), these problems have been fixed in version 9.4.39-3+deb11u2. For the stable     distribution (bookworm), these problems have been fixed in version 9.4.50-4+deb12u1. We recommend that you     upgrade your jetty9 packages.
