Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) 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.


2) 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.


3) Improper input validation (CVE-ID: CVE-2021-37137)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the Content Acquisition System (Netty) component in Oracle Commerce Guided Search. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.


4) Resource exhaustion (CVE-ID: CVE-2021-37136)

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 in Bzip2 decompression decoder function. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


5) Input validation error (CVE-ID: CVE-2015-2156)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Netty before 3.9.8.Final, 3.10.x before 3.10.3.Final, 4.0.x before 4.0.28.Final, and 4.1.x before 4.1.0.Beta5 and Play Framework 2.x before 2.3.9 might allow remote attackers to bypass the httpOnly flag on cookies and obtain sensitive information by leveraging improper validation of cookie name and value characters.


6) 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.
