Detailsinfo

A vulnerability was found in Crestron TSW-1060, TSW-760, TSW-560, TSW-1060-NC, TSW-760-NC and TSW-560-NC up to 2.001. It has been classified as critical. This affects some unknown processing of the component CTP. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Crestron TSW-1060, TSW-760, TSW-560, TSW-1060-NC, TSW-760-NC, and TSW-560-NC devices before 2.001.0037.001 allow unauthenticated remote code execution via a Bash shell service in Crestron Toolbox Protocol (CTP).
