Descriptions

A vulnerability in Cisco WebEx Recording Format (WRF) Player could allow an unauthenticated, remote attacker to access sensitive data about the application. An attacker could exploit this vulnerability to gain information to conduct additional reconnaissance attacks. The vulnerability is due to a design flaw in Cisco WRF Player. An attacker could exploit this vulnerability by utilizing a maliciously crafted file that could bypass checks in the code and enable an attacker to read memory from outside the bounds of the mapped file. This vulnerability affects Cisco WebEx Business Suite meeting sites, Cisco WebEx Meetings sites, and Cisco WebEx WRF players. Cisco Bug IDs: CSCvh89107, CSCvh89113, CSCvh89132, CSCvh89142.

Un atacante podría explotar esta vulnerabilidad para obtener información y realizar ataques adicionales de reconocimiento. La vulnerabilidad se debe a un fallo de diseño en Cisco WRF Player. Un atacante podría explotar esta vulnerabilidad empleando un archivo maliciosamente manipulado que podría omitir comprobaciones en el código y permitir que el atacante lea memoria de fuera de los límites del archivo mapeado. Esta vulnerabilidad afecta a sitios de reunión Cisco WebEx Business Suite, Cisco WebEx Meetings y a los reproductores Cisco WebEx WRF. Cisco Bug IDs: CSCvh89107, CSCvh89113, CSCvh89132, CSCvh89142.

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Cisco WebEx Recorder and Player. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the processing of WRF files. Crafted data in a WRF file can trigger a read past the end of a mapped view of a file. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
