CSRF Vulnerability in Symfony's CSRF Protection Implementation

CVE-2017-16653 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:N/A:N

An issue was discovered in Symfony before 2.7.38, 2.8.31, 3.2.14, 3.3.13, 3.4-BETA5, and 4.0-BETA5. The current implementation of CSRF protection in Symfony (Version >=2) does not use different tokens for HTTP and HTTPS; therefore the token is subject to MITM attacks on HTTP and can then be used in an HTTPS context to do CSRF attacks.
