HTTP Request Smuggling

Overview io.netty:netty-codec-http is a network application framework for rapid development of maintainable high performance protocol servers & clients. Affected versions of this package are vulnerable to HTTP Request Smuggling via the getChunkSize function. An attacker can inject unauthorized HT...

Netty vulnerable to HTTP Request Smuggling due to incorrect chunk size parsing

Summary Netty's chunk size parser silently overflows int, enabling request smuggling attacks. Details io.netty.handler.codec.http.HttpObjectDecodergetChunkSize silently overflows int. The size is accumulated as follows: result = 16; result += digit; The result is checked only for negative values...
