CVE-2019-1826

A vulnerability in the quality of service (QoS) feature of Cisco Aironet Series Access Points (APs) could allow an authenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation on QoS fields within Wi-Fi frames by the affected device. An attacker could exploit this vulnerability by sending malformed Wi-Fi frames to an affected device. A successful exploit could allow the attacker to cause the affected device to crash, resulting in a DoS condition.

CVE-2019-1800

A vulnerability in the handling of Inter-Access Point Protocol (IAPP) messages by Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. The vulnerability exist because the software improperly validates input on fields within IAPP messages. An attacker could exploit the vulnerability by sending malicious IAPP messages to an affected device. A successful exploit could allow the attacker to cause the Cisco WLC Software to reload, resulting in a DoS condition. Software versions prior to 8.2.170.0, 8.5.150.0, and 8.8.100.0 are affected.

CVE-2019-1805

A vulnerability in certain access control mechanisms for the Secure Shell (SSH) server implementation for Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, adjacent attacker to access a CLI instance on an affected device. The vulnerability is due to a lack of proper input- and validation-checking mechanisms for inbound SSH connections on an affected device. An attacker could exploit this vulnerability by attempting to establish an SSH connection to an affected controller. An exploit could allow the attacker to access an affected device’s CLI to potentially cause further attacks. This vulnerability has been fixed in version 8.5(140.0).

CVE-2019-1802

A vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected system. The vulnerability is due to insufficient validation of user-supplied input in the web-based management interface of the affected system. An attacker could exploit this vulnerability by persuading a user to access a report containing malicious content. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. Versions 6.2.3, 6.3.0, and 6.4.0 are affected.

CVE-2019-1797

A vulnerability in the web-based management interface of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on the device with the privileges of the user, including modifying the device configuration. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading an interface user to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on the device with the privileges of the user. Software versions prior to 8.3.150.0, 8.5.135.0, and 8.8.100.0 are affected.

CVE-2019-1799

A vulnerability in the handling of Inter-Access Point Protocol (IAPP) messages by Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. The vulnerability exist because the software improperly validates input on fields within IAPP messages. An attacker could exploit the vulnerability by sending malicious IAPP messages to an affected device. A successful exploit could allow the attacker to cause the Cisco WLC Software to reload, resulting in a DoS condition. Software versions prior to 8.2.170.0, 8.5.150.0, and 8.8.100.0 are affected.

CVE-2019-1796

A vulnerability in the handling of Inter-Access Point Protocol (IAPP) messages by Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. The vulnerability exist because the software improperly validates input on fields within IAPP messages. An attacker could exploit the vulnerability by sending malicious IAPP messages to an affected device. A successful exploit could allow the attacker to cause the Cisco WLC Software to reload, resulting in a DoS condition. Software versions prior to 8.2.170.0, 8.5.150.0, and 8.8.100.0 are affected.

CVE-2019-1794

A vulnerability in the search path processing of Cisco Directory Connector could allow an authenticated, local attacker to load a binary of their choosing. The vulnerability is due to uncontrolled search path elements. An attacker could exploit this vulnerability by placing a binary of their choosing earlier in the search path utilized by Cisco Directory Connector to locate and load required resources.

CVE-2019-1792

A vulnerability in the URL block page of Cisco Umbrella could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user in a network protected by Umbrella. The vulnerability is due to insufficient validation of input parameters passed to that page. An attacker could exploit this vulnerability by persuading a user of the interface to click a maliciously crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive browser-based information. This vulnerability has been fixed in the current version of Cisco Umbrella. Cisco Umbrella is a cloud service.

CVE-2019-1777

A vulnerability in the web-based interface of the Cisco Registered Envelope Service could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against another user of the service. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected software. An attacker could exploit this vulnerability by sending an email with a malicious payload to another user. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. This vulnerability affects software versions 5.3.4.x.
