| Vulnerability Name: | CVE-2011-0228 (CCN-68781) |
| Assigned: | 2010-12-23 |
| Published: | 2011-07-26 |
| Updated: | 2018-10-10 |
| Summary: | The Data Security component in Apple iOS before 4.2.10 and 4.3.x before 4.3.5 does not check the basicConstraints parameter during validation of X.509 certificate chains, which allows man-in-the-middle attackers to spoof an SSL server by using a non-CA certificate to sign a certificate for an arbitrary domain.
