Improper Input Validation

org.apache.httpcomponents:httpclient is a HttpClient component of the Apache HttpComponents project.

How to fix Improper Input Validation?

Upgrade org.apache.httpcomponents:httpclient to version 4.5.13 or higher.

Man-in-the-Middle (MitM)

org.apache.httpcomponents:httpclient is a HttpClient component of the Apache HttpComponents project.

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM) due to not verifing the requesting server's hostname agains existing domain names in the SSL Certificate. The AbstractVerifier does not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a certificate with a subject that specifies a common name in a field that is not the CN field.

NOTE: this issue exists because of an incomplete fix for CVE-2012-5783.

How to fix Man-in-the-Middle (MitM)?

Upgrade org.apache.httpcomponents:httpclient to version 4.2.3 or higher.

Directory Traversal

org.apache.httpcomponents:httpclient is a HttpClient component of the Apache HttpComponents project.

Affected versions of this package are vulnerable to Directory Traversal. String input by user is not validated for the presence of leading character / and is passed to the constructor as path information, resulting in a Directory Traversal vulnerability.

How to fix Directory Traversal?

Upgrade org.apache.httpcomponents:httpclient to version 4.5.3 or higher.

Man-in-the-Middle (MitM)

org.apache.httpcomponents:httpclient is an HttpClient component of the Apache HttpComponents project.

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM) due to not verify the requesting server's hostname against existing domain names in the SSL Certificate.

The AbstractVerifier does not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a "CN=" string in a field in the distinguished name (DN) of a certificate, as demonstrated by the "foo,CN=www.apache.org" string in the O field.

How to fix Man-in-the-Middle (MitM)?

Upgrade org.apache.httpcomponents:httpclient to version 4.3.4 or higher.
