Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) CRLF injection
EUVDB-ID: #VU26412
Risk: Medium
CVSSv3.1: 4.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2019-11236
CWE-ID:
CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a spoofing attack.
The vulnerability exists due to insufficient filtration of user-supplied data passed via HTTP request parameters to urllib3 library. A remote attacker can pass specially crafted data that contains CRLF sequences and perform a spoofing attack.
Install update from vendor's website.

2) CRLF injection
EUVDB-ID: #VU47403
Risk: Medium
CVSSv3.1: 4.4 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-26137
CWE-ID:
CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to inject arbitrary data in server response.
The vulnerability exists due to insufficient validation of attacker-supplied data passed via the "method" parameter. A remote authenticated attacker can pass specially crafted data to the application containing CR-LF characters and modify application behavior.
