Exploring Command Injection Vulnerabilities in Windows with Nim
Here's a summarized table based on the testing results from the Nim code experiments with different payloads:
| Payload | execProcess_NoQuoteShell | execProcess_QuoteShell | execShellCmd |
|---|---|---|---|
nim &calc |
Not Passed | Not Passed | Passed |
nim" &calc |
Passed | Not Passed | Not Passed |
%CMDCMDLINE:~-1%&calc |
Passed | Passed | Passed |
"Passed" indicates the payload executed in a way that could potentially exploit the BatBadBut vulnerability, demonstrating the nuanced behavior of command execution methods in Nim in response to different types of inputs.
