CVSS: 8.6EPSS: 0%CPEs: 3EXPL: 0CVE-2018-15460 – Cisco Email Security Appliance URL Filtering Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15460
A vulnerability in the email message filtering feature of Cisco AsyncOS Software for Cisco Email Security Appliances (ESA) could allow an unauthenticated, remote attacker to cause the CPU utilization to increase to 100 percent, causing a denial of service (DoS) condition on an affected device. The vulnerability is due to improper filtering of email messages that contain references to whitelisted URLs. An attacker could exploit this vulnerability by sending a malicious email message that contains a large number of whitelisted URLs. A successful exploit could allow the attacker to cause a sustained DoS condition that could force the affected device to stop scanning and forwarding email messages. Una vulnerabilidad en la funcionalidad de filtrado de mensajes de correo electrónico de Cisco AsyncOS Software para Cisco Email Security Appliances (ESA) podría permitir que un atacante remoto no autenticado aumente el uso de la CPU hasta el 100 por ciento, provocando una condición de denegación de servicio (DoS) en un dispositivo afectado. • http://www.securityfocus.com/bid/106507 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190109-esa-url-dos • CWE-20: Improper Input Validation CWE-770: Allocation of Resources Without Limits or Throttling •

A vulnerability in the FTP server of the Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to log in to the FTP server of the device without a valid password. The attacker does need to have a valid username. The vulnerability is due to incorrect FTP user credential validation. An attacker could exploit this vulnerability by using FTP to connect to the management IP address of the targeted device. A successful exploit could allow the attacker to log in to the FTP server of the Cisco WSA without having a valid password. • http://www.securityfocus.com/bid/103407 http://www.securitytracker.com/id/1040464 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180307-wsa • CWE-287: Improper Authentication •

A vulnerability in the administrative shell of Cisco AsyncOS on Cisco Email Security Appliance (ESA) and Content Security Management Appliance (SMA) could allow an authenticated, local attacker to escalate their privilege level and gain root access. The attacker has to have a valid user credential with at least a privilege level of a guest user. The vulnerability is due to an incorrect networking configuration at the administrative shell CLI. An attacker could exploit this vulnerability by authenticating to the targeted device and issuing a set of crafted, malicious commands at the administrative shell. An exploit could allow the attacker to gain root access on the device. • http://www.securityfocus.com/bid/102729 http://www.securitytracker.com/id/1040221 http://www.securitytracker.com/id/1040222 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180117-esasma • CWE-264: Permissions, Privileges, and Access Controls •

A vulnerability in the Advanced Malware Protection (AMP) file filtering feature of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to bypass a configured AMP file filtering rule. The file types affected are zipped or archived file types. The vulnerability is due to incorrect and different file hash values when AMP scans the file. An attacker could exploit this vulnerability by sending a crafted email file attachment through the targeted device. An exploit could allow the attacker to bypass a configured AMP file filter. • http://www.securityfocus.com/bid/101932 http://www.securitytracker.com/id/1039828 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171115-wsa • CWE-358: Improperly Implemented Security Check for Standard •

A vulnerability in the email message filtering feature of Cisco AsyncOS Software for the Cisco Email Security Appliance could allow an unauthenticated, remote attacker to cause an affected device to run out of memory and stop scanning and forwarding email messages. When system memory is depleted, it can cause the filtering process to crash, resulting in a denial of service (DoS) condition on the device. This vulnerability affects software version 9.0 through the first fixed release of Cisco AsyncOS Software for Cisco Email Security Appliances, both virtual and hardware appliances, if the software is configured to apply a message filter or content filter to incoming email attachments. The vulnerability is not limited to any specific rules or actions for a message filter or content filter.
