Cisco Intelligent Contact Manager contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code. Updates are available.
Cisco Intelligent Contact Manager versions prior to 7.0 contain a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on the targeted system.
The vulnerability is due to improper boundary checking on user-supplied input. An unauthenticated, remote attacker could exploit the vulnerability by sending malicious requests to the targeted system. If successful, the attacker could execute arbitrary code.
Cisco has confirmed this vulnerability in software release notes; however, software updates are not available.
Cisco Intelligent Contact Manager versions prior to 7.0 are vulnerable.
To exploit the vulnerability, an attacker must be able to send malicious requests to a targeted system. Because the vulnerable application process accepts input on a TCP port that is typically blocked by external requests, the attacker may require access to internal networks to accomplish an exploit.
The vulnerability does not exist in Cisco Intelligent Contact Manager 7.0 because the vulnerable executable, agent.exe, was removed in that release.
The vulnerabilities were discovered and reported to Cisco by a researcher working with TippingPoint's Zero Day Initiative.
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on the targeted system with elevated privileges, possibly resulting in a complete system compromise.
The vulnerability is due to improper boundary checking on user-supplied input that is processed by the agent.exe service. The service accepts input via TCP port 40078. The service fails to properly check the length of input before use in memory operations. The processing of overly large parameters could trigger a stack-based buffer overflow condition.
An unauthenticated, remote attacker could exploit the vulnerability by sending a malicious request to the targeted application. When processed, the request could trigger a stack overflow that corrupts memory. The attacker could take advantage of the memory corruption to execute arbitrary code with the SYSTEM level privileges of the agent.exe process.
Administrators are advised to apply software updates as they become available.
Administrators may consider removing the agent.exe executable from affected systems.
Administrators are advised to filter requests received via TCP port 40078.
Administrators are advised to monitor critical systems.
