Posted Aug 3, 2012
Authored by Suman Jana, Vitaly Shmatikov, Martin Georgiev | Site libcloud.apache.org

Apache Libcloud versions 0.4.2 through 0.11.1 suffer from a possible man-in-the-middle condition. When establishing a secure (SSL / TLS) connection to a target server an invalid regular expression has been used for performing the hostname verification. Subset instead of the full target server hostname has been marked as an acceptable match for the given hostname.

CVE-2012-3446: Apache Libcloud - possible MITM due to invalid regular
expression used to validate the target server hostname

Severity: Medium

Vendor:

The Apache Software Foundation

Versions Affected:

Apache Libcloud 0.4.2 to 0.11.1

Versions prior to 0.4.2 don't perform any target server SSL certificate
validation.

Description:

When establishing a secure (SSL / TLS) connection to a target server an
invalid regular expression has been used for performing the hostname
verification. Subset instead of the full target server hostname has been
marked an an acceptable match for the given hostname.

For example, certificate with a hostname field of "aexample.com" was
considered
a valid certificate for domain "example.com".

Mitigation:

Users should upgrade to the latest version (0.11.1) which includes a fix.
