CVE-2014-3310

Vulnerability

The File Transfer feature in Cisco WebEx Meetings Client, as used in Cisco WebEx Meetings Server and WebEx Meeting Center, does not validate that a requested file was actually offered during the session. This allows an attacker to read arbitrary files on the server by sending a modified request. The vulnerability is identified by Bug IDs CSCup62442 and CSCup58463. [1]

Exploitation

An attacker can exploit this vulnerability by crafting a malicious request to the File Transfer feature. No authentication is required if the attacker can reach the affected service, though specific network positioning may be needed to interact with the WebEx server. The attacker simply sends a request for a file path that was not offered, bypassing the intended restriction. [1]

Impact

Successful exploitation allows a remote attacker to read arbitrary files from the Cisco WebEx Meetings Server or Meeting Center. This can lead to exposure of sensitive information, including configuration files, user data, or other confidential data stored on the server. [1]

Mitigation

Cisco released a security notice for this vulnerability. Affected users should apply the appropriate software updates provided by Cisco. As of the publication date (2014-07-10), specific fixed versions were not disclosed in the available reference; however, Cisco recommends following their security advisories for patches. [1]
