Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
IPython (Interactive Python) is a command shell for interactive computing in multiple programming languages, originally developed for the Python programming language. Versions prior to 8.10 are subject to a command injection vulnerability with very specific prerequisites. This vulnerability requires that the function "IPython.utils.terminal.set_term_title" be called on Windows in a Python environment where ctypes is not available. The dependency on "ctypes" in `IPython.utils._process_win32` prevents the vulnerable code from ever being reached in the ipython binary. However, as a library that could be used by another tool "set_term_title" could be called and hence introduce a vulnerability. Should an attacker get untrusted input to an instance of this function they would be able to inject shell commands as current process and limited to the scope of the current process. Users of ipython as a library are advised to upgrade. Users unable to upgrade should ensure that any calls to the "IPython.utils.terminal.set_term_title" function are done with trusted or filtered input.
CWE-78 - OS Command Injection
The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
