Example 1, the code in this example allows an attacker to execute arbitrary commands with the elevated privilege of the application.

Because the program does not validate the value read from the environment, by controlling the environment variable the attacker may fool the application into running malicious code.make in the /var/yp directory. Note that since the program updates password records, it has been installed setuid root.make as follows:
system("cd /var/yp && make &> /dev/null");
system(). However, since the program does not specify an absolute path for make and does not scrub any environment variables prior to invoking the command, the attacker may modify their $PATH variable to point to a malicious binary named make and execute the CGI script from a shell prompt. And since the program has been installed setuid root, the attacker's version of make now runs with root privileges.CreateProcess() either directly or via a call to one of the functions in the _spawn() family, care must be taken when there is a space in an executable or path.
...
LPTSTR cmdLine = _tcsdup(TEXT("C:\\Program Files\\MyApplication -L -S"));
CreateProcess(NULL, cmdLine, ...);
...
CreateProcess() parses spaces, the first executable the operating system will try to execute is Program.exe, not MyApplication.exe. Therefore, if an attacker is able to install a malicious application called Program.exe on the system, any program that incorrectly calls CreateProcess() using the Program Files directory will run this application instead of the intended one.system(), exec(), and CreateProcess() use the environment of the program that calls them, and therefore attackers have a potential opportunity to influence the behavior of these calls.$PATH or other aspects of the program's execution environment.make in the /var/yp directory.

However, because the program does not specify an absolute path for make and does not scrub its environment variables prior to invoking the command, the attacker can modify their $PATH variable to point to a malicious binary named make and execute the CGI script from a shell prompt. In addition, because the program has been installed setuid root, the attacker's version of make now runs with root privileges.pdfprint command.

This is an unnecessary cross-site scripting threat, resulting in stolen cookies. Stolen cookies can contain sensitive information identifying the user to the site, such as the ASP.NET session ID or forms authentication ticket, and can be replayed by the attacker in order to masquerade as the user or obtain sensitive information.

__Host- or __Secure- prefix must have the Secure attribute set, must not set Domain attribute, and must restrict Path attribute value to /.__Host- and __Secure- prefix must be set with the secure attribute. They must be set from a secure page (HTTPS). Additionally, a __Host- prefixed cookie must not have a domain attribute specified (so that it is not sent to subdomains) and the path attribute must be set to /. Violation of these rules can cause a browser to reject the cookie. Restricting a cookie's access to a secure channel protects it from being sent or being overwritten by a forged site over an unencrypted HTTP channel. Restrictions provided by the __Host prefix prevent a cookie from being accessed by a subdomain where the subdomain might be owned by different entities such as a shared blog platform.SameSite attribute on session cookies.SameSite parameter limits the scope of the cookie so that it is only attached to a request if the request is generated from first-party or same-site context. This helps to protect cookies from Cross-Site Request Forgery (CSRF) attacks. The SameSite parameter can have the following three values:Strict, cookies are only sent along with requests upon top-level navigation.Lax, cookies are sent with top-level navigation from the same host as well as GET requests originated to the host from third-party sites. For example, suppose a third-party site has either iframe or href tags that link to the host site. If a user follows the link, the request will include the cookie.SameSite attribute to None for session cookies.
