Cisco Webex Network Recording Player and Cisco Webex Player Remote Code Execution Vulnerabilities
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.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Cisco Webex Network Recording Player and Webex Player for Windows improperly validate ARF/WRF files, allowing remote code execution via malicious file.
Vulnerability
A vulnerability exists in the Cisco Webex Network Recording Player for Microsoft Windows and the Cisco Webex Player for Microsoft Windows due to improper validation of Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. This affects all versions prior to the fixed releases provided in the Cisco security advisory [1]. The code path is reachable when a user opens a specially crafted ARF or WRF file with the affected software.
Exploitation
An attacker can exploit this vulnerability by sending a malicious ARF or WRF file to a target user via a link or email attachment and persuading the user to open the file using the affected player. No additional privileges or network position beyond delivering the file and inducing the user to open it are required [1].
Impact
Successful exploitation allows the attacker to execute arbitrary code on the affected system with the privileges of the user running the software. This can lead to full compromise of confidentiality, integrity, and availability of the system [1].
Mitigation
Cisco has released free software updates to address this vulnerability. The fixed versions are specified in the Cisco Security Advisory cisco-sa-20181003-webex-rce [1]. Customers are advised to upgrade to the latest versions. No workarounds are available for this vulnerability.
