2) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU61681

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-2021-4189

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input in the FTP (File Transfer Protocol) client library when using it in PASV (passive) mode. A remote attacker can set up a malicious FTP server, trick the FTP client in Python into connecting back to a given IP address and port, which can lead to FTP client scanning ports which otherwise would not have been possible.

Mitigation

Update the affected package python to the latest version.

3) CRLF injection

EUVDB-ID: #VU61675

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-0391

CWE-ID: CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to inject arbitrary data in server response.

The vulnerability exists due to insufficient validation of attacker-supplied data within the urllib.parse module in Python. A remote attacker can pass specially crafted data to the application containing CR-LF characters and modify application behavior.

Mitigation

Update the affected package python to the latest version.
