Cisco TelePresence VCS version X7.0.3 is vulnerable.
To exploit the vulnerability, an attacker would likely need access to trusted, internal networks. This access requirement may limit the likelihood of a successful attack.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
An unauthenticated, remote attacker could exploit the vulnerability to bypass security restrictions and gain unauthorized access to the policy service use by the affected software. Successful exploitation could allow an attacker to create a conference using Conductor.
The vulnerability occurs when the affected software processes certain search rules. Users could bypass security restrictions imposed by the affected software and have unauthorized access to the policy service used by the affected software.
An unauthenticated, remote attacker could exploit this vulnerability to access the policy service. If successful, an attacker could create a conference using Conductor, which could be used to conduct further attacks.
Administrators are advised to contact the vendor regarding future updates and releases.
