Name of the Vulnerable Software and Affected Versions wincred versions all

Description The issue allows an attacker to execute arbitrary commands if attacker-controlled user input is given to the getCredential function. This is due to the use of the child process exec function without input sanitization, which can lead to command execution.

Recommendations For all versions, consider disabling the getCredential function until a patch is available to prevent exploitation. Restrict access to the child process exec function to minimize the risk of arbitrary command execution. Avoid using the getCredential function with untrusted input until the issue is resolved.
