CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 1CVE-2023-4043 – Parsson DoS when parsing numbers from untrusted sources
https://notcve.org/view.php?id=CVE-2023-4043
In Eclipse Parsson before versions 1.1.4 and 1.0.5, Parsing JSON from untrusted sources can lead malicious actors to exploit the fact that the built-in support for parsing numbers with large scale in Java has a number of edge cases where the input text of a number can lead to much larger processing time than one would expect. To mitigate the risk, parsson put in place a size limit for the numbers as well as their scale. En Eclipse Parsson antes de las versiones 1.1.4 y 1.0.5, el Parsing JSON de fuentes no confiables puede llevar a actores maliciosos a explotar el hecho de que el soporte integrado para analizar números a gran escala en Java tiene varios casos extremos en los que el texto de entrada de un número puede llevar a un tiempo de procesamiento mucho mayor de lo que cabría esperar. Para mitigar el riesgo, parsson estableció un límite de tamaño para los números y su escala. A flaw was found in Eclipse Parsson library when processing untrusted source content. This issue may cause a Denial of Service (DoS) due to built-in support for parsing numbers with a large scale, and some cases where processing a large number may take much more time than expected. • https://github.com/eclipse-ee4j/parsson/pull/100 https://gitlab.eclipse.org/security/vulnerability-reports/-/issues/13 https://access.redhat.com/security/cve/CVE-2023-4043 https://bugzilla.redhat.com/show_bug.cgi?id=2254594 • CWE-20: Improper Input Validation CWE-834: Excessive Iteration •

https://notcve.org/view.php?id=CVE-2023-5763
In Eclipse Glassfish 5 or 6, running with old versions of JDK (lower than 6u211, or < 7u201, or < 8u191), allows remote attackers to load malicious code on the server via access to insecure ORB listeners. En Eclipse Glassfish 5 o 6, ejecutado con versiones antiguas de JDK (inferiores a 6u211, o < 7u201, o < 8u191), permite a atacantes remotos cargar código malicioso en el servidor mediante el acceso a oyentes ORB inseguros. • https://gitlab.eclipse.org/security/cve-assignement/-/issues/14 https://glassfish.org/docs/latest/security-guide.html#securing-glassfish-server • CWE-20: Improper Input Validation CWE-913: Improper Control of Dynamically-Managed Code Resources •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-5632 – Unconditionally adding an event to the epoll causes excessive CPU consumption
https://notcve.org/view.php?id=CVE-2023-5632
In Eclipse Mosquito before and including 2.0.5, establishing a connection to the mosquitto server without sending data causes the EPOLLOUT event to be added, which results excessive CPU consumption. This could be used by a malicious actor to perform denial of service type attack. This issue is fixed in 2.0.6 En Eclipse Mosquito anterior a 2.0.5 incluida, establecer una conexión con el servidor mosquitto sin enviar datos provoca que se agregue el evento EPOLLOUT, lo que resulta en un consumo excesivo de CPU. Esto podría ser utilizado por un actor malintencionado para realizar un ataque de tipo de denegación de servicio. Este problema se solucionó en 2.0.6. • https://github.com/eclipse/mosquitto/commit/18bad1ff32435e523d7507e9b2ce0010124a8f2d https://github.com/eclipse/mosquitto/pull/2053 • CWE-834: Excessive Iteration •
CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 1CVE-2023-36478 – HTTP/2 HPACK integer overflow and buffer allocation
https://notcve.org/view.php?id=CVE-2023-36478
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. • http://www.openwall.com/lists/oss-security/2023/10/18/4 https://github.com/eclipse/jetty.project/pull/9634 https://github.com/eclipse/jetty.project/releases/tag/jetty-10.0.16 https://github.com/eclipse/jetty.project/releases/tag/jetty-11.0.16 https://github.com/eclipse/jetty.project/releases/tag/jetty-9.4.53.v20231009 https://github.com/eclipse/jetty.project/security/advisories/GHSA-wgh7-54f2-x98r https://lists.debian.org/debian-lts-announce/2023/10/msg00045.html https:&# • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 83%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
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. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •
