CVSS: 5.5EPSS: 0%CPEs: 10EXPL: 0CVE-2022-20717 – Cisco SD-WAN vEdge Routers Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20717
A vulnerability in the NETCONF process of Cisco SD-WAN vEdge Routers could allow an authenticated, local attacker to cause an affected device to run out of memory, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient memory management when an affected device receives large amounts of traffic. An attacker could exploit this vulnerability by sending malicious traffic to an affected device. A successful exploit could allow the attacker to cause the device to crash, resulting in a DoS condition. Una vulnerabilidad en el proceso NETCONF de los routers Cisco SD-WAN vEdge podría permitir a un atacante local autenticado causar a un dispositivo afectado quedarse sin memoria, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdwan-vedge-dos-jerVm4bB • CWE-770: Allocation of Resources Without Limits or Throttling CWE-789: Memory Allocation with Excessive Size Value •
CVSS: 8.5EPSS: 2%CPEs: 71EXPL: 1CVE-2021-44832 – Apache Log4j2 vulnerable to RCE via JDBC Appender when attacker controls configuration
https://notcve.org/view.php?id=CVE-2021-44832
Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. Las versiones de Apache Log4j2 de la 2.0-beta7 a la 2.17.0 (excluyendo las versiones de corrección de seguridad 2.3.2 y 2.12.4) son vulnerables a un ataque de ejecución remota de código (RCE) cuando una configuración utiliza un JDBC Appender con un URI de origen de datos JNDI LDAP cuando un atacante tiene el control del servidor LDAP de destino. Este problema se soluciona limitando los nombres de fuentes de datos JNDI al protocolo java en las versiones 2.17.1, 2.12.4 y 2.3.2 de Log4j2 Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack where an attacker with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. • https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 http://www.openwall.com/lists/oss-security/2021/12/28/1 https://cert-portal.siemens.com/productcert/pdf/ssa-784507.pdf https://issues.apache.org/jira/browse/LOG4J2-3293 https://lists.apache.org/thread/s1o5vlo78ypqxnzn6p8zf6t9shtq5143 https://lists.debian.org/debian-lts-announce/2021/12/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject • CWE-20: Improper Input Validation CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 7.8EPSS: 0%CPEs: 115EXPL: 0CVE-2021-1529 – Cisco IOS XE SD-WAN Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1529
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to execute arbitrary commands with root privileges. The vulnerability is due to insufficient input validation by the system CLI. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input to the system CLI. A successful exploit could allow the attacker to execute commands on the underlying operating system with root privileges.

https://notcve.org/view.php?id=CVE-2021-1621
A vulnerability in the Layer 2 punt code of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a queue wedge on an interface that receives specific Layer 2 frames, resulting in a denial of service (DoS) condition. This vulnerability is due to improper handling of certain Layer 2 frames. An attacker could exploit this vulnerability by sending specific Layer 2 frames on the segment the router is connected to. A successful exploit could allow the attacker to cause a queue wedge on the interface, resulting in a DoS condition.

CVSS: 7.7EPSS: 0%CPEs: 965EXPL: 0CVE-2021-1620 – Cisco IOS and IOS XE Software IKEv2 AutoReconnect Feature Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1620
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) support for the AutoReconnect feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to exhaust the free IP addresses from the assigned local pool. This vulnerability occurs because the code does not release the allocated IP address under certain failure conditions. An attacker could exploit this vulnerability by trying to connect to the device with a non-AnyConnect client. A successful exploit could allow the attacker to exhaust the IP addresses from the assigned local pool, which prevents users from logging in and leads to a denial of service (DoS) condition.
