Description: XSS filter bypass is a technique used to circumvent protection mechanisms against Cross-Site Scripting (XSS) attacks. This type of attack allows an attacker to inject malicious scripts into web pages viewed by other users. Filter bypass refers to the strategies that attackers employ to evade security measures implemented by web developers, such as input validation and output encoding. XSS filters are designed to detect and block potentially dangerous content, but attackers can use various techniques, such as code obfuscation, the use of special characters, or manipulation of the script structure, to deceive these filters. The relevance of this technique lies in its ability to compromise the security of web applications, which can result in the exposure of sensitive data, identity theft, and other significant damages. Understanding XSS filter bypass is crucial for cybersecurity professionals, as it allows them to strengthen their applications’ defenses and protect users from potential attacks.
