CVE-2013-7397 not yet assigned priority: Debian including 1 source packages (async-http-client), 3 status rows across 3 suites (bookworm, bullseye, sid): resolved 3.
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.
