python-glanceclient vulnerable to SSL server spoofing due to unverified X.509 certificate
CVE-2013-4111 · GHSA-qgfg-gvff-523v
- Affected
- PyPI python-glanceclient < 0.10.0
- Fixed in
- 0.10.0· Vendor fix available
- Issue
- The Python client library for Glance (python-glanceclient) before 0.10.0 does not properly check the preverifyok value, which prevents the server hostname from being verified with a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate and allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
Recommended action: Upgrade to 0.10.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
