A vulnerability in System Status Collection Daemon (SSCD) code could
allow an unauthenticated, adjacent attacker to execute arbitrary
commands with the privilege of the root user.
is due to improper validation of parameters passed to the SSCD code via
an XML-remote procedure call (RPC). An attacker could exploit this vulnerability by sending crafted
XML-RPC messages. An exploit could allow the attacker to execute
arbitrary calls via stack corruption with the privilege of the root user.
Cisco has confirmed the vulnerability in a security advisory and released software updates.
Indicators of Compromise
Cisco TelePresence System Software versions prior to 1.10.2(42) running on the following Cisco TelePresence System hardware platforms are affected:
Cisco TelePresence System 500-37
Cisco TelePresence System 1000
Cisco TelePresence System 1300-65
Cisco TelePresence System 3000
Cisco TelePresence System 3010
Cisco TelePresence System 3200
Cisco TelePresence System 3210
Cisco TelePresence System Software versions prior to 6.0.4(11) running on the following Cisco TelePresence System hardware platforms are affected:
Cisco TelePresence System 500-32
Cisco TelePresence System 1300-47
Cisco TelePresence System TX1310 65
Cisco TelePresence System TX9000
Cisco TelePresence System TX9200
The vulnerability is due to insufficient validation of parameters passed to the SSCD code of the affected software via an XML-RPC.
An unauthenticated, adjacent attacker could exploit this vulnerability by sending crafted XML-RPC messages. An exploit could allow the attacker to execute arbitrary calls via stack corruption with the privilege of the root user. A successful exploit could result in a complete system compromise.
To exploit this vulnerability, an attacker would need access to the same broadcast or collision domain of the targeted device. This access requirement decreases the likelihood of a successful exploit.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to have network access.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
Administrators are advised to monitor affected systems.
