Medium
| Vector | AV:N/AC:M/Au:N/C:P/I:P/A:N |
Name of the Vulnerable Software and Affected Versions
Services Twitter version 0.6.3
Description
The issue arises from the failure to verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate. This allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
Recommendations
For version 0.6.3, ensure that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate to prevent man-in-the-middle attacks. Consider implementing certificate pinning or verifying the subjectAltName field as a temporary workaround until a patch is available.
