Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2020-11612)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within ZlibDecoders in Netty while decoding a ZlibEncoded byte stream. A remote attacker can trigger resource exhaustion by passing an overly large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.
2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2019-20444)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to incorrect processing of HTTP headers without the colon within the HttpObjectDecoder.java file in Netty. A remote attacker can send a specially crafted HTTP request to the application and perform HTTP request smuggling attack.
3) HTTP response splitting (CVE-ID: CVE-2019-20445)
The vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not corrector process CRLF character sequences within the HttpObjectDecoder.java in Netty, which allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.
4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2019-16869)
The vulnerability allows a remote attacker to perform HTTP request smuggling attack.
The vulnerability exists due to improper input validation when processing a whitespace before the colon in HTTP headers (e.g. "Transfer-Encoding : chunked"). A remote attacker can send a specially crafted HTTP request and perform HTTP request smuggling attack.
