Thank you. CVE-2021-37533: Apache Commons Net's FTP client trusts the host from PASV response by defaultOn 2022-12-03, the Apache Commons Text team disclosed CVE-2021-37533 Severity: low Prior to Apache Commons Net 3.9.0, Net's FTP client trusts the host from PASV response by default. A malicious server can redirect the Commons Net code to use a different host, but the user has to connect to the malicious server in the first place. This may lead to leakage of information about services running on the private network of the client. The default in version 3.9.0 is now false to ignore such hosts, as cURL does. See NET-711. Credit: Apache Commons would like to thank ZeddYu Lu for reporting this issue. References: |
