Trust: 0.8

sources: JVNDB: JVNDB-2017-010395

DESCRIPTION

A "Cisco WebEx Network Recording Player Remote Code Execution Vulnerability" exists in Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) and WebEx Recording Format (WRF) files. A remote attacker could exploit this by providing a user with a malicious ARF or WRF file via email or URL and convincing the user to launch the file. Exploitation of this could cause an affected player to crash and, in some cases, could allow arbitrary code execution on the system of a targeted user. Cisco Bug IDs: CSCvf57234, CSCvg54868, CSCvg54870. Vendors have confirmed this vulnerability Bug ID CSCvf57234 , CSCvg54868 ,and CSCvg54870 It is released as.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Authentication is not required to exploit this vulnerability.The specific flaw exists within the wbx URI handler. When parsing the register parameter, the process does not properly validate a user-supplied string before using it to execute a system command. An attacker can leverage this vulnerability to execute commands under the context of the current user. Multiple Cisco WebEx Products are prone to the following security vulnerabilities: 1. Multiple remote code-execution vulnerabilities 2. Failed exploit attempts will likely result in denial-of-service conditions. Cisco WebEx Business Suite (WBS30) client and so on are the client software of Cisco's video conferencing solution. The following products and versions are affected: Cisco WebEx Business Suite (WBS30) client builds prior to T30.20; WebEx Business Suite (WBS31) client builds prior to T31.14.1; WebEx Business Suite (WBS32) client builds prior to T32.2 versions before WebEx Meetings with client builds prior to T31.14; versions prior to WebEx Meeting Server builds 2.7MR3
