eskaleringstunnel

An eskaleringstunnel, often translated as escalation tunnel, is a term used in cybersecurity and software development to describe a specific type of vulnerability. It refers to a situation where a less privileged process or user can gain elevated privileges or access to sensitive resources by exploiting a flaw in how the system handles or escalates commands or requests. This typically occurs when a program is designed to perform certain operations with higher permissions but lacks proper validation or sanitization of the inputs it receives during this escalation process.

The core mechanism of an eskaleringstunnel involves an attacker finding a way to trick a privileged program into executing arbitrary code or commands on their behalf. This could be through buffer overflows, command injection, or insecurely configured inter-process communication channels. The "tunnel" aspect implies that the attacker is using the legitimate escalation path of the privileged program as a conduit to bypass intended security restrictions. Successful exploitation allows the attacker to act with the same privileges as the compromised program, potentially leading to full system compromise, data theft, or service disruption.

Preventing eskaleringstunnels relies on robust security practices in software development. This includes rigorous input validation and sanitization for all data processed by privileged programs, principle of least privilege, secure coding standards, and regular security audits and penetration testing. By ensuring that escalation mechanisms are tightly controlled and cannot be manipulated, systems can defend against this class of vulnerability.
