TITLE

Cisco Webex Network Recording Player and Webex Player Input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-010862

DESCRIPTION

A vulnerability in the Cisco Webex Network Recording Player for Microsoft Windows and the Cisco Webex Player for Microsoft Windows could allow an attacker to execute arbitrary code on an affected system. The vulnerability exist because the affected software improperly validates Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. An attacker could exploit this vulnerability by sending a user a malicious ARF or WRF file via a link or an email attachment and persuading the user to open the file by using the affected software. A successful exploit could allow the attacker to execute arbitrary code on the affected system. Cisco Webex Network Recording Player and Webex Player Contains an input validation vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. When parsing an ARF file, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. These issues are being tracked by Cisco Bug IDs CSCvj63665, CSCvj63672, CSCvj63676, CSCvj63717, CSCvj63724, CSCvj63729, CSCvj67334, CSCvj67339, and CSCvj67344.
