No. We are not aware of malware exploiting this vulnerability.

2) Information disclosure

EUVDB-ID: #VU55488

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-31810

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists within Net::FTP in Ruby when processing PASV responses. A remote attacker can trick the victim to connect to a malicious FTP server and trick Net::FTP into connecting back to a given IP address and port. This potentially makes curl extract information about services that are otherwise private and not disclosed (e.g., the attacker can conduct port scans and service banner extractions).

Mitigation

Install updates from vendor's repository.
