Unverified50% confidenceFactExact time
A WAF can block common command-concatenation signatures, anomalous encoded payloads and known exploit patterns for RCE, but encoding bypasses, chunked transfer, protocol parsing differences and zero-day vulnerabilities can all evade detection.

UnverifiedBusiness logic vulnerabilities cannot be identified by general-purpose security devices such as WAFs, because WAFs rely on matching known attack signatures, while the requests involved in logic vulnerabilities are completely legitimate at the syntactic level.73% similarUnverifiedstack-UAF 类 Linux 漏洞通常可导致权限提升、任意代码执行和拒绝服务71% similarUnverifiedMemory corruption vulnerabilities involve low-level flaws such as out-of-bounds reads and writes, use-after-free (UAF), or buffer overflows, which may cause process crashes or even remote code execution.70% similarUnverifiedBlindly injecting large numbers of payloads will trigger WAFs and cause the IP to be blocked, making it impossible to detect vulnerabilities even if they exist in the target.69% similarUnverifiedVirtual patching (such as WAF rules), although unable to fundamentally fix a vulnerability, can reduce the risk of exploitation before the official patch is in place.68% similar
