Description

Multiple vulnerabilities in the web-based management interface of Cisco Intersight Virtual Appliance could allow an authenticated, remote attacker to conduct a path traversal or command injection attack on an affected system. These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by using the web-based management interface to do one or both of the following: Execute a command using crafted input Upload a file that has been altered using path traversal techniques A successful exploit could allow the attacker to read and write arbitrary files or execute arbitrary commands as root on an affected system. For more information about these vulnerabilities, see the Details section of this advisory.

• CWE-36Absolute Path TraversalThe product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as "/abs/path" that can resolve to a location that is outside of that directory.
• CWE-78Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
