There exists a security vulnerability in Jetty's DosFilter which can be exploited by unauthorized users to cause remote denial-of-service (DoS) attack on the server using DosFilter. By repeatedly sending crafted requests, attackers can trigger OutofMemory errors and exhaust the server's memory finally.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5894 advisory.

    Package        : jetty9     CVE ID         : CVE-2024-6762 CVE-2024-8184 CVE-2024-9823     Debian Bug     : 1085697

    Jetty 9 is a Java based web server and servlet engine. Several security     vulnerabilities have been discovered which may allow remote attackers to cause     a denial of service by repeatedly sending crafted requests which can trigger     OutofMemory errors and exhaust the server's memory.

    CVE-2024-6762: In addition PushSessionCacheFilter and PushCacheFilter have been     deprecated. These classes should no longer be used in a production environment.

    For the stable distribution (bookworm), these problems have been fixed in     version 9.4.57-0+deb12u1.

    We recommend that you upgrade your jetty9 packages.

    For the detailed security status of jetty9 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/jetty9

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

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.

It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2702 advisory.
