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 •
CVSS: 7.5EPSS: 15%CPEs: 72EXPL: 0CVE-2021-4104 – Deserialization of untrusted data in JMSAppender in Apache Log4j 1.2
https://notcve.org/view.php?id=CVE-2021-4104
JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. • http://www.openwall.com/lists/oss-security/2022/01/18/3 https://access.redhat.com/security/cve/CVE-2021-4104 https://github.com/apache/logging-log4j2/pull/608#issuecomment-990494126 https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2021-0033 https://security.gentoo.org/glsa/202209-02 https://security.gentoo.org/glsa/202310-16 https://security.gentoo.org/glsa/202312-02 https://security.gentoo.org/glsa/202312-04 https://security.netapp.com/advisory/ntap-20211223-0007 https&# • CWE-20: Improper Input Validation CWE-502: Deserialization of Untrusted Data •

https://notcve.org/view.php?id=CVE-2020-27782
A flaw was found in the Undertow AJP connector. Malicious requests and abrupt connection closes could be triggered by an attacker using query strings with non-RFC compliant characters resulting in a denial of service. The highest threat from this vulnerability is to system availability. This affects Undertow 2.1.5.SP1, 2.0.33.SP2, and 2.2.3.SP1. Se encontró un fallo en el conector AJP de Undertow. • https://bugzilla.redhat.com/show_bug.cgi?id=1901304 https://access.redhat.com/security/cve/CVE-2020-27782 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 6.8EPSS: 0%CPEs: 12EXPL: 1CVE-2020-25689 – wildfly-core: memory leak in WildFly host-controller in domain mode while not able to reconnect to domain-controller
https://notcve.org/view.php?id=CVE-2020-25689
A memory leak flaw was found in WildFly in all versions up to 21.0.0.Final, where host-controller tries to reconnect in a loop, generating new connections which are not properly closed while not able to connect to domain-controller. This flaw allows an attacker to cause an Out of memory (OOM) issue, leading to a denial of service. The highest threat from this vulnerability is to system availability. Se encontró una fallo de filtrado de memoria en WildFly en todas las versiones hasta 21.0.0.Final, donde el controlador de host intenta reconectarse en un bucle, generando nuevas conexiones que no son cerradas apropiadamente mientras no es capaz de conectar al controlador de dominio. Este fallo permite a un atacante causar un problema de Falta de Memoria (OOM), conllevando a una denegación de servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-25689 https://security.netapp.com/advisory/ntap-20201123-0006 https://access.redhat.com/security/cve/CVE-2020-25689 https://bugzilla.redhat.com/show_bug.cgi?id=1893070 • CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2020-14340
A vulnerability was discovered in XNIO where file descriptor leak caused by growing amounts of NIO Selector file handles between garbage collection cycles. It may allow the attacker to cause a denial of service. It affects XNIO versions 3.6.0.Beta1 through 3.8.1.Final. Se detectó una vulnerabilidad en XNIO en la que se produce un filtrado de descriptores de archivos causada por el crecimiento de la cantidad de manejadores de archivos NIO Selector entre los ciclos de recolección de basura.
