Telepresence Video Communication Server Software

The Mobile and Remote Access (MRA) component in Cisco TelePresence Video Communication Server (VCS) X8.1 through X8.7 and Expressway X8.1 through X8.6 mishandles certificates, which allows remote attackers to bypass authentication via an arbitrary trusted certificate, aka Bug ID CSCuz64601.Show less

Cisco TelePresence Video Communication Server (VCS) X8.1 through X8.7, as used in conjunction with Jabber Guest, allows remote attackers to obtain sensitive call-statistics information via a direct request to an unspecified URL, aka Bug ID CSCux73362.Show less

The Mobile and Remote Access (MRA) services implementation in Cisco Unified Communications Manager mishandles edge-device identity validation, which allows remote attackers to bypass intended call-reception and call-setup restrictions by spoofing a user, aka Bug ID CSCuu97283.Show less

Cisco TelePresence Video Communication Server (VCS) X8.6 uses the same encryption key across different customers' installations, which makes it easier for local users to defeat cryptographic protection mechanisms by leveraging knowledge of a key from another installation, aka Bug ID CSCuw64516.Show less

Cisco TelePresence Video Communication Server (VCS) Expressway X8.6 allows remote authenticated users to bypass intended read-only restrictions and upload Tandberg Linux Package (TLP) files by visiting an administrative page, aka Bug ID CSCuw55651.Show less

The process-management implementation in Cisco TelePresence Video Communication Server (VCS) Expressway X8.5.2 allows local users to gain privileges by terminating a firestarter.py supervised process and then triggering the restart of a process by the root account, aka Bug ID CSCuv12272.Show less

Cisco TelePresence Video Communication Server (VCS) Expressway X8.5.2 allows remote authenticated users to bypass intended access restrictions and read configuration files by leveraging the Mobile and Remote Access (MRA) role and establishing a TFTP session, aka Bug ID CSCuv78531.Show less

The password-change feature in the administrative web interface in Cisco TelePresence Video Communication Server (VCS) Expressway X8.5.1 improperly performs authorization, which allows remote authenticated users to reset arbitrary active-user passwords via unspecified vectors, aka Bug ID CSCuv12338.Show less

The Mobile and Remote Access (MRA) endpoint-validation feature in Cisco TelePresence Video Communication Server (VCS) Expressway X8.5.2 improperly validates the phone line used for registration, which allows remote authenticated users to conduct impersonation attacks via a crafted registration, aka Bug ID CSCuv40396.Show less

Cisco TelePresence Video Communication Server (VCS) X8.5.2 allows remote authenticated users to execute arbitrary commands in the context of the nobody user account via an unspecified web-page parameter, aka Bug ID CSCuv12333.Show less

Cisco TelePresence Video Communication Server (VCS) Expressway X8.5.2 improperly checks for a user account's read-only attribute, which allows remote authenticated users to execute arbitrary OS commands via crafted HTTP requests, as demonstrated by read or write operations on the Unified Communications lookup page, aka Bug ID CSCuv12552.Show less

The Configuration Log File component in Cisco TelePresence Video Communication Server (VCS) Expressway X8.5.2 allows remote authenticated users to obtain sensitive information by reading a log file, aka Bug ID CSCuv12340.Show less
