Description Jan Lieskovsky 2013-02-12 13:17:54 UTC
Originally, Common Vulnerabilities and Exposures assigned an identifier CVE-2012-5783 to the following vulnerability:

Apache Commons HttpClient 3.x, as used in Amazon Flexible Payments Service (FPS) merchant Java SDK and other products, does not 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 an arbitrary valid certificate.

Later it was found, that the SSL hostname verifier implementation (CVE-2012-5783 fix) contained a bug in wildcard matching:
[1] https://issues.apache.org/jira/browse/HTTPCLIENT-1255

which still allowed certain type of certificates checks to pass, even if they shouldn't.

Relevant upstream patches:

    (against 4.2.x branch)

    (against trunk)

This issue affects the versions of the jakarta-commons-httpclient package, as shipped with Fedora release of 17 and 18. Please schedule an update.

Created jakarta-commons-httpclient tracking bugs for this issue

Affects: fedora-all [bug 910363]

Comment 5 Jan Lieskovsky 2013-02-12 13:49:41 UTC
Taking back. This is not a security issue. We have previously investigated it with the following conclusion:

> /* Should HTTPCLIENT-1255 one be also classified as (another) CVE id? */

It is my understanding that this bug will cause valid certificates to be rejected, but not for invalid certificates to be accepted. Therefore I do not think it qualifies for a CVE ID.
