CVE’s

A vulnerability in the Cisco Aironet Series Access Points (APs) software could allow an authenticated, adjacent attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to a deadlock condition that may occur when an affected AP attempts to dequeue aggregated traffic that is destined to an attacker-controlled wireless client. An attacker who can successfully transition between multiple Service Set Identifiers (SSIDs) hosted on the same AP while replicating the required traffic patterns could trigger the deadlock condition. A watchdog timer that detects the condition will trigger a reload of the device, resulting in a DoS condition while the device restarts.

Multiple vulnerabilities exist in the Cisco Webex Network Recording Player for Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. An attacker could exploit these vulnerabilities by providing a user with a malicious .arf or .wrf file via email or URL and convincing the user to launch the file in the Webex recording players. Exploitation of these vulnerabilities could cause an affected player to crash, resulting in a denial of service (DoS) condition. The Cisco Webex players are applications that are used to play back Webex meetings that have been recorded by an online meeting attendee. The Webex Network Recording Player for .arf files can be automatically installed when the user accesses a recording that is hosted on a Webex server. The Webex Player for .wrf files can be downloaded manually. These vulnerabilities affect ARF and WRF recording players available from Cisco Webex Meetings Suite sites, Cisco Webex Meetings Online sites, and Cisco Webex Meetings Server. Cisco Bug IDs: CSCvh70253, CSCvh70268, CSCvh72272, CSCvh72281, CSCvh72285, CSCvi60477, CSCvi60485, CSCvi60490, CSCvi60520, CSCvi60529, CSCvi60533.

Multiple vulnerabilities exist in the Cisco Webex Network Recording Player for Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. An attacker could exploit these vulnerabilities by providing a user with a malicious .arf or .wrf file via email or URL and convincing the user to launch the file in the Webex recording players. Exploitation of these vulnerabilities could allow arbitrary code execution on the system of a targeted user. These vulnerabilities affect ARF and WRF recording players available from Cisco Webex Meetings Suite sites, Cisco Webex Meetings Online sites, and Cisco Webex Meetings Server. Cisco Bug IDs: CSCvi02621, CSCvi02965, CSCvi63329, CSCvi63333, CSCvi63335, CSCvi63374, CSCvi63376, CSCvi63377, CSCvi63391, CSCvi63392, CSCvi63396, CSCvi63495, CSCvi63497, CSCvi63498, CSCvi82684, CSCvi82700, CSCvi82705, CSCvi82725, CSCvi82737, CSCvi82742, CSCvi82760, CSCvi82771, CSCvj51284, CSCvj51294.

A vulnerability in the Precision Time Protocol (PTP) feature of Cisco Nexus 5500, 5600, and 6000 Series Switches running Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of protection against PTP frame flood attacks. An attacker could exploit this vulnerability by sending large streams of malicious IPv4 or IPv6 PTP traffic to the affected device. A successful exploit could allow the attacker to cause a DoS condition, impacting the traffic passing through the device.

A vulnerability in the Open Systems Gateway initiative (OSGi) interface of Cisco Policy Suite before 18.1.0 could allow an unauthenticated, remote attacker to directly connect to the OSGi interface. The vulnerability is due to a lack of authentication. An attacker could exploit this vulnerability by directly connecting to the OSGi interface. An exploit could allow the attacker to access or change any files that are accessible by the OSGi process. Cisco Bug IDs: CSCvh18017.

A vulnerability in the Policy Builder interface of Cisco Policy Suite before 18.2.0 could allow an unauthenticated, remote attacker to access the Policy Builder interface. The vulnerability is due to a lack of authentication. An attacker could exploit this vulnerability by accessing the Policy Builder interface. A successful exploit could allow the attacker to make changes to existing repositories and create new repositories. Cisco Bug IDs: CSCvi35109.

A vulnerability in the Cluster Manager of Cisco Policy Suite before 18.2.0 could allow an unauthenticated, remote attacker to log in to an affected system using the root account, which has default, static user credentials. The vulnerability is due to the presence of undocumented, static user credentials for the root account. An attacker could exploit this vulnerability by using the account to log in to an affected system. An exploit could allow the attacker to log in to the affected system and execute arbitrary commands as the root user. Cisco Bug IDs: CSCvh02680.

A vulnerability in the Policy Builder database of Cisco Policy Suite before 18.2.0 could allow an unauthenticated, remote attacker to connect directly to the Policy Builder database. The vulnerability is due to a lack of authentication. An attacker could exploit this vulnerability by connecting directly to the Policy Builder database. A successful exploit could allow the attacker to access and change any data in the Policy Builder database. Cisco Bug IDs: CSCvh06134.

A vulnerability in vpnva-6.sys for 32-bit Windows and vpnva64-6.sys for 64-bit Windows of Cisco AnyConnect Secure Mobility Client for Windows Desktop could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected system. The vulnerability is due to improper validation of user-supplied data. An attacker could exploit this vulnerability by sending a malicious request to the application. A successful exploit could allow the attacker to cause a DoS condition on the affected system. Cisco Bug IDs: CSCvj47654.

A vulnerability in the DHCPv6 feature of the Cisco Nexus 9000 Series Fabric Switches in Application-Centric Infrastructure (ACI) Mode could allow an unauthenticated, remote attacker to cause the device to run low on system memory, which could result in a Denial of Service (DoS) condition on an affected system. The vulnerability is due to improper memory management when DHCPv6 packets are received on an interface of the targeted device. An attacker could exploit this vulnerability by sending a high number of malicious DHCPv6 packets to be processed by an affected device. A successful exploit could allow the attacker to cause the system to run low on memory, which could cause an eventual reboot of an affected device. The vulnerability only applies to IPv6 protocol packets and not for IPv4 protocol packets. This vulnerability affects Cisco Nexus 9000 Series Fabric Switches in ACI Mode running software version 13.0(1k). The vulnerability can only be exploited when unicast routing is enabled on the Bridge Domain (BD). DHCP and DHCP relay do not have to be configured for the vulnerability to be exploited. Cisco Bug IDs: CSCvg38918.
