csrf_exempt
In C, the csrf_exempt
attribute is used to indicate that a specific function or variable should be exempted from Cross-Site Request Forgery (CSRF) protection. By applying the csrf_exempt
attribute to a function or variable, it tells the compiler or code analyzer to skip the CSRF protection checks for that specific entity.
Here's an example of how the csrf_exempt
attribute can be used in C:
#include <stdio.h>
__attribute__((csrf_exempt))
void vulnerableFunction()
{
printf("This function is exempt from CSRF protection.\n");
}
int main()
{
vulnerableFunction();
return 0;
}
In the example above, the vulnerableFunction
is marked with the csrf_exempt
attribute, which means that it will not be subject to CSRF protection. When the vulnerableFunction
is called, it will execute without any CSRF checks.
Please note that the csrf_exempt
attribute is not a standard feature of the C language, but it can be implemented using compiler-specific or platform-specific attributes or directives. The example provided uses the __attribute__((csrf_exempt))
syntax, which is specific to certain compilers.
It's important to exercise caution when using the csrf_exempt
attribute, as it can potentially introduce security vulnerabilities if not used properly.
