CVSS: 10.0EPSS: 96%CPEs: 398EXPL: 30CVE-2021-44228 – Apache Log4j2 Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-44228
Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. • https://github.com/fullhunt/log4j-scan https://github.com/Puliczek/CVE-2021-44228-PoC-log4j-bypass-words https://github.com/cyberstruggle/L4sh https://github.com/woodpecker-appstore/log4j-payload-generator https://github.com/tangxiaofeng7/apache-log4j-poc https://www.exploit-db.com/exploits/51183 https://www.exploit-db.com/exploits/50592 https://www.exploit-db.com/exploits/50590 https://github.com/logpresso/CVE-2021-44228-Scanner https://github.com/jas502n/Log4j2-CVE-2021-44228 h • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption CWE-502: Deserialization of Untrusted Data CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •
CVSS: 7.5EPSS: 0%CPEs: 25EXPL: 0CVE-2021-34736 – Cisco Integrated Management Controller GUI Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34736
A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Software could allow an unauthenticated, remote attacker to cause the web-based management interface to unexpectedly restart. The vulnerability is due to insufficient input validation on the web-based management interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to cause the interface to restart, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la interfaz de administración basada en web de Cisco Integrated Management Controller (IMC) Software podría permitir a un atacante remoto no autenticado causar el reinicio inesperado de la interfaz de administración basada en web. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-imc-gui-dos-TZjrFyZh • CWE-20: Improper Input Validation •
CVSS: 5.3EPSS: 0%CPEs: 105EXPL: 0CVE-2021-1590 – Cisco NX-OS Software system login block-for Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1590
A vulnerability in the implementation of the system login block-for command for Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a login process to unexpectedly restart, causing a denial of service (DoS) condition. This vulnerability is due to a logic error in the implementation of the system login block-for command when an attack is detected and acted upon. An attacker could exploit this vulnerability by performing a brute-force login attack on an affected device. A successful exploit could allow the attacker to cause a login process to reload, which could result in a delay during authentication to the affected device. Una vulnerabilidad en la implementación del comando system login block-for para el Software Cisco NX-OS, podría permitir a un atacante remoto no autenticado causar que un proceso de inicio de sesión se reinicie inesperadamente, causando una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-login-blockfor-RwjGVEcu • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-1368
A vulnerability in the Unidirectional Link Detection (UDLD) feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code with administrative privileges or cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted Cisco UDLD protocol packets to a directly connected, affected device. A successful exploit could allow the attacker to execute arbitrary code with administrative privileges or cause the Cisco UDLD process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition. Note: The UDLD feature is disabled by default, and the conditions to exploit this vulnerability are strict. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-udld-rce-xetH6w35 • CWE-787: Out-of-bounds Write •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2019-1725 – Cisco UCS B-Series Blade Servers Local Management CLI Arbitrary File Creation or CLI Parameter Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1725
A vulnerability in the local management CLI implementation for specific commands on the Cisco UCS B-Series Blade Servers could allow an authenticated, local attacker to overwrite an arbitrary file on disk. It is also possible the attacker could inject CLI command parameters that should not be allowed for a specific subset of local management CLI commands. The vulnerability is due to lack of proper input validation of user input for local management CLI commands. An attacker could exploit this vulnerability by authenticating to the device and issuing a crafted form of a limited subset of local management CLI commands. An exploit could allow the attacker to overwrite an arbitrary files on disk or inject CLI command parameters that should have been disabled. • http://www.securityfocus.com/bid/108082 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-ucs-cli-inj • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
