📚 What is Web Cache Poisoning ? ​

Web Cache Poisoning is a sophisticated attack technique where an attacker exploits the behavior of web caches to store a malicious HTTP response. This response is then served to unsuspecting users, leading to various harmful outcomes such as the execution of malicious scripts, data leakage, or unauthorized actions.

Web caches are used to improve performance and reduce latency by storing copies of HTTP responses for reuse. When a cache is poisoned, it can serve harmful content instead of the legitimate content intended for users.

The primary goal of web cache poisoning is to manipulate the cached content in a way that it impacts a large number of users, making it a highly effective attack vector.

Understanding and mitigating web cache poisoning is essential for maintaining the integrity and security of web applications.

📌 Key Concepts and Impact ​

Web cache poisoning can have severe consequences for web applications, including :

  • Unauthorized Access: Attackers can inject scripts or alter content, leading to unauthorized actions by users.
  • Data Leakage: Sensitive information can be exposed to unintended recipients.
  • Service Disruption: Poisoned caches can disrupt normal service, causing downtime or degraded performance.
  • Reputational Damage: Serving malicious content can harm the reputation of the affected organization.

In the following sections, we will dive into the specifics of various vulnerabilities that contribute to web cache poisoning and how to protect against them.
