Detailsinfo

A vulnerability classified as critical has been found in Cisco Application Policy Infrastructure Controller (the affected version is unknown). This affects an unknown code of the component Script File. The manipulation with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability in certain system script files that are installed at boot time on Cisco Application Policy Infrastructure Controllers could allow an authenticated, local attacker to gain elevated privileges and execute arbitrary commands with root privileges on an affected host operating system. The vulnerability is due to insufficient validation of user-controlled input that is supplied to certain script files of an affected system. An attacker could exploit this vulnerability by submitting crafted input to a script file on an affected system. A successful exploit could allow the attacker to gain elevated privileges and execute arbitrary commands with root privileges on the affected system. To exploit this vulnerability, the attacker would need to authenticate to the affected system by using valid administrator credentials. Cisco Bug IDs: CSCvf57274.
