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 update from vendor's website.
Vulnerable software versionswatsonx.data: before 2.0.2
CPE2.3http://www.ibm.com/support/pages/node/7167142
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
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.
MitigationInstall update from vendor's website.
Vulnerable software versionswatsonx.data: before 2.0.2
CPE2.3http://www.ibm.com/support/pages/node/7167142
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
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 update from vendor's website.
