TITLE

Cisco Webex Network Recording Player and Cisco Webex Player Buffer error vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-001449

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 email attachment and persuading the user to open the file with the affected software. Successful exploitation could allow the attacker to execute arbitrary code on the affected system. Crafted data in an ARF file can trigger a write past the end of an allocated buffer. These issues are being tracked by Cisco Bug IDs CSCvm65148, CSCvm65207, CSCvm65741, CSCvm65747, CSCvm65794, CSCvm65798, CSCvm86137, CSCvm86143, CSCvm86148, CSCvm86157, CSCvm86160, and CSCvm86165. Cisco Webex Business Suite WBS32 sites and so on are the video conferencing solutions of Cisco (Cisco). The following products are affected: Cisco Webex Business Suite WBS32 sites; Webex Business Suite WBS33 sites; Webex Meetings Online; Webex Meetings Server
