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: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2021-40128 – Cisco Webex Meetings Email Content Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-40128
A vulnerability in the account activation feature of Cisco Webex Meetings could allow an unauthenticated, remote attacker to send an account activation email with an activation link that points to an arbitrary domain. This vulnerability is due to insufficient validation of user-supplied parameters. An attacker could exploit this vulnerability by sending a crafted HTTP request to the account activation page of Cisco Webex Meetings. A successful exploit could allow the attacker to send to any recipient an account activation email that contains a tampered activation link, which could direct the user to an attacker-controlled website. Una vulnerabilidad en la funcionalidad account activation de Cisco Webex Meetings podría permitir a un atacante remoto no autenticado enviar un correo electrónico de activación de cuentas con un enlace de activación que apunte a un dominio arbitrario. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-activation-3sdNFxcy • CWE-183: Permissive List of Allowed Inputs •

https://notcve.org/view.php?id=CVE-2021-34743
A vulnerability in the application integration feature of Cisco Webex Software could allow an unauthenticated, remote attacker to authorize an external application to integrate with and access a user's account without that user's express consent. This vulnerability is due to improper validation of cross-site request forgery (CSRF) tokens. An attacker could exploit this vulnerability by convincing a targeted user who is currently authenticated to Cisco Webex Software to follow a link designed to pass malicious input to the Cisco Webex Software application authorization interface. A successful exploit could allow the attacker to cause Cisco Webex Software to authorize an application on the user's behalf without the express consent of the user, possibly allowing external applications to read data from that user's profile. Una vulnerabilidad en la funcionalidad application integration de Cisco Webex Software podría permitir a un atacante remoto no autenticado autorizar a una aplicación externa a integrarse y acceder a la cuenta de un usuario sin el consentimiento expreso de éste. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-2FmKd7T • CWE-352: Cross-Site Request Forgery (CSRF) •

https://notcve.org/view.php?id=CVE-2021-1544
A vulnerability in logging mechanisms of Cisco Webex Meetings client software could allow an authenticated, local attacker to gain access to sensitive information. This vulnerability is due to unsafe logging of application actions. An attacker could exploit this vulnerability by logging onto the local system and accessing files containing the logged details. A successful exploit could allow the attacker to gain access to sensitive information, including meeting data and recorded meeting transcriptions. Una vulnerabilidad en los mecanismos de registro del software cliente Cisco Webex Meetings podría permitir a un atacante local autentificado acceder a información sensible. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-8fpBnKOz • CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2021-1536 – Cisco Webex Meetings, Webex Network Recording Player, and Webex Teams DLL Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1536
A vulnerability in Cisco Webex Meetings Desktop App for Windows, Cisco Webex Meetings Server, Cisco Webex Network Recording Player for Windows, and Cisco Webex Teams for Windows could allow an authenticated, local attacker to perform a DLL injection attack on an affected device. To exploit this vulnerability, the attacker must have valid credentials on the Windows system. This vulnerability is due to incorrect handling of directory paths at run time. An attacker could exploit this vulnerability by inserting a configuration file in a specific path in the system, which can cause a malicious DLL file to be loaded when the application starts. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of another user account. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-dll-inject-XNmcSGTU • CWE-427: Uncontrolled Search Path Element •
