CWE-20

A vulnerability in the administrative GUI configuration feature of Cisco Wireless LAN Controller (WLC) Software could allow an aUTHENTICated, remote attacker to cause the device to reload unexpectedly during device configuration when the administrator is using this GUI, causing a denial of service (DoS) condition on an affected device. The attacker would need to have valid administrator credentials on the device. This vulnerability is due to incomplete input validation for unexpected configuration options that the attacker could submit while accessing the GUI configuration menus. An attacker could exploit these vulnerabilities by authenticating to the device and submitting crafted user input when using the administrative GUI configuration feature. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Software versions prior to 8.3.150.0, 8.5.140.0, 8.8.111.0 are affected by this vulnerability.

A vulnerability in the ACS Report component of Cisco Secure Access Control System (ACS) could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected system. Commands executed by the attacker are processed at the targeted user’s privilege level. The vulnerability is due to insufficient validation of the Action Message Format (AMF) protocol. An attacker could exploit this vulnerability by sending a crafted AMF message that contains malicious code to a targeted user. A successful exploit could allow the attacker to execute arbitrary commands on the ACS device. This vulnerability affects all releases of Cisco Secure ACS prior to Release 5.8 Patch 7. Cisco Bug IDs: CSCve69037.

A vulnerability in the peer-to-peer message processing functionality of Cisco Packet Data Network Gateway could allow an unauthenticated, remote attacker to cause the Session Manager (SESSMGR) process on an affected device to restart, resulting in a denial of service (DoS) condition. The vulnerability is due to incorrect validation of peer-to-peer packet headers. An attacker could exploit this vulnerability by sending a crafted peer-to-peer packet through an affected device. A successful exploit could allow the attacker to cause the SESSMGR process on the affected device to restart unexpectedly, which could briefly impact traffic while the SESSMGR process restarts and result in a DoS condition. Cisco Bug IDs: CSCvg88786.

A vulnerability in the web interface of Cisco MATE Live could allow an unauthenticated, remote attacker to view and download the contents of certain web application virtual directories. The vulnerability is due to lack of proper input validation and authorization of HTTP requests. An attacker could exploit this vulnerability by sending a malicious HTTP request to the targeted application. An exploit could allow the attacker to view sensitive information that should require authentication. Cisco Bug IDs: CSCvh31272.

A vulnerability in the Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) files could allow an unauthenticated, remote attacker to execute arbitrary code on the system of a targeted user. An attacker could exploit this vulnerability by sending the user a link or email attachment with a malicious ARF file and persuading the user to follow the link or open the file. Successful exploitation could allow the attacker to execute arbitrary code on the user’s system. This vulnerability affects Cisco WebEx Business Suite meeting sites, Cisco WebEx Meetings sites, Cisco WebEx Meetings Server, and Cisco WebEx ARF players. The following client builds of Cisco WebEx Business Suite (WBS31 and WBS32), Cisco WebEx Meetings, and Cisco WebEx Meetings Server are affected: Cisco WebEx Business Suite (WBS31) client builds prior to T31.23.4, Cisco WebEx Business Suite (WBS32) client builds prior to T32.12, Cisco WebEx Meetings with client builds prior to T32.12, Cisco WebEx Meeting Server builds prior to 3.0 Patch 1. Cisco Bug IDs: CSCvh85410, CSCvh85430, CSCvh85440, CSCvh85442, CSCvh85453, CSCvh85457.

A vulnerability in the Real-Time Transport Protocol (RTP) bitstream processing of the Cisco Meeting Server could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient input validation of incoming RTP bitstreams. An attacker could exploit this vulnerability by sending a crafted RTP bitstream to an affected Cisco Meeting Server. A successful exploit could allow the attacker to deny audio and video services by causing media process crashes resulting in a DoS condition on the affected product. This vulnerability affects Cisco Meeting Server deployments that are running Cisco Meeting Server Software Releases 2.0, 2.1, 2.2, and 2.3. Cisco Bug IDs: CSCve79693, CSCvf91393, CSCvg64656, CSCvh30725, CSCvi86363.
