CVE-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 •
CVE-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 •
CVE-2016-6325 – tomcat: tomcat writable config files allow privilege escalation
https://notcve.org/view.php?id=CVE-2016-6325
The Tomcat package on Red Hat Enterprise Linux (RHEL) 5 through 7, JBoss Web Server 3.0, and JBoss EWS 2 uses weak permissions for (1) /etc/sysconfig/tomcat and (2) /etc/tomcat/tomcat.conf, which allows local users to gain privileges by leveraging membership in the tomcat group. El paquete Tomcat en Red Hat Enterprise Linux (RHEL) 5 hasta la versión 7, JBoss Web Server 3.0 y JBoss EWS 2 utiliza permisos débiles para (1) /etc/sysconfig/tomcat y (2) /etc/tomcat/tomcat.conf, lo que permite a usuarios locales obtener privilegios aprovechando su pertenencia al grupo tomcat. It was discovered that the Tomcat packages installed certain configuration files read by the Tomcat initialization script as writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges. • http://rhn.redhat.com/errata/RHSA-2016-2045.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://rhn.redhat.com/errata/RHSA-2017-0457.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93478 https://access.redhat.com/errata/RHSA-2017:0455 https://access.redhat.com/errata/RHSA-2017:0456 https://bugzilla.redhat.com/show_bug.cgi?id=1367447 https://access.redhat.com/security/cve/CVE-2016-6325 • CWE-264: Permissions, Privileges, and Access Controls CWE-284: Improper Access Control •
CVE-2016-2183 – SSL/TLS: Birthday attack against 64-bit block ciphers (SWEET32)
https://notcve.org/view.php?id=CVE-2016-2183
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack. Los cifrados DES y Triple DES, como se usan en los protocolos TLS, SSH e IPSec y otros protocolos y productos, tienen una cota de cumpleaños de aproximadamente cuatro mil millones de bloques, lo que facilita a atacantes remotos obtener datos de texto plano a través de un ataque de cumpleaños contra una sesión cifrada de larga duración, según lo demostrado por una sesión HTTPS usando Triple DES en modo CBC, también conocido como un ataque "Sweet32". A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite. IBM Informix Dynamic Server suffers from dll injection, PHP code injection, and heap buffer overflow vulnerabilities. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
