In Eclipse Jetty version 9.4.0.RC0 to 9.4.34.v20201102, 10.0.0.alpha0 to 10.0.0.beta2, and 11.0.0.alpha0 to 11.0.0.beta2, if GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single connection, and if an attacker can send a request with a body that is received entirely but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body. The attacker will not see any data but may inject data into the body of the subsequent request.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3641 advisory.

  - In Eclipse Jetty version 9.4.0.RC0 to 9.4.34.v20201102, 10.0.0.alpha0 to 10.0.0.beta2, and 11.0.0.alpha0     to 11.0.0.beta2, if GZIP request body inflation is enabled and requests from different clients are     multiplexed onto a single connection, and if an attacker can send a request with a body that is received     entirely but not consumed by the application, then a subsequent request on the same connection will see     that body prepended to its body. The attacker will not see any data but may inject data into the body of     the subsequent request. (CVE-2020-27218)

  - 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)

  - 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)

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

The version of Jetty installed on the remote host suffers from a flaw where the buffer is not correctly recycled in Gzip request inflation. This may permit an attacker to inject data into the body of the subsequent request Note that the scanner has not tested for this issue but has instead relied only on the application's self-reported version number.
