Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Inconsistent interpretation of HTTP requests
EUVDB-ID: #VU22825
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-16869
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe 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.
Install updates from vendor's repository.

2) Inconsistent interpretation of HTTP requests
EUVDB-ID: #VU25355
Risk: Medium
CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2019-20444
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe 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
EUVDB-ID: #VU25598
Risk: Medium
CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-20445
CWE-ID:
CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')
Exploit availability: No
DescriptionThe 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.
MitigationInstall updates from vendor's repository.
