Vulnerability CVE-2013-7397
Published: 2015-06-24

Description:
Async Http Client (aka AHC or async-http-client) before 1.9.0 skips X.509 certificate verification unless both a keyStore location and a trustStore location are explicitly set, which allows man-in-the-middle attackers to spoof HTTPS servers by presenting an arbitrary certificate during use of a typical AHC configuration, as demonstrated by a configuration that does not send client certificates.

Type:

CWE-345

 (Insufficient Verification of Data Authenticity)
