Cisco Webex Network Recording Player and Cisco Webex Player Arbitrary Code Execution Vulnerabilities
Description
Multiple vulnerabilities in Cisco Webex Network Recording Player for Microsoft Windows and Cisco Webex Player for Microsoft Windows could allow an attacker to execute arbitrary code on an affected system. The vulnerabilities exist because the affected software improperly validates Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. An attacker could exploit these vulnerabilities by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file with the affected software on the local system. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the targeted user.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Cisco Webex Network Recording Player and Webex Player for Windows contain multiple arbitrary code execution vulnerabilities due to improper validation of ARF and WRF files.
Vulnerability
The vulnerabilities exist in Cisco Webex Network Recording Player and Cisco Webex Player for Microsoft Windows. The software fails to properly validate Advanced Recording Format (ARF) and Webex Recording Format (WRF) files, allowing an attacker to craft malicious files that trigger memory corruption or other issues leading to code execution. All versions prior to the fixed releases are affected [1].
Exploitation
An attacker can exploit these vulnerabilities by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file with the affected software on the local system. No authentication is required, but user interaction is necessary [1].
Impact
Successful exploitation allows the attacker to execute arbitrary code on the affected system with the privileges of the targeted user. This could lead to full compromise of the user's system and data [1].
Mitigation
