Symfony 2.3.x before 2.3.35, 2.6.x before 2.6.12, and 2.7.x before 2.7.7 might allow remote attackers to have unspecified impact via a timing attack involving the (1) Symfony/Component/Security/Http/RememberMe/PersistentTokenBasedRememberMeServices or (2) Symfony/Component/Security/Http/Firewall/DigestAuthenticationListener class in the Symfony Security Component, or (3) legacy CSRF implementation from the Symfony/Component/Form/Extension/Csrf/CsrfProvider/DefaultCsrfProvider class in the Symfony Form component.
Session fixation vulnerability in the "Remember Me" login feature in Symfony 2.3.x before 2.3.35, 2.6.x before 2.6.12, and 2.7.x before 2.7.7 allows remote attackers to hijack web sessions via a session id.
Eval injection vulnerability in the HttpCache class in HttpKernel in Symfony 2.x before 2.3.27, 2.4.x and 2.5.x before 2.5.11, and 2.6.x before 2.6.6 allows remote attackers to execute arbitrary PHP code via a language="php" attribute of a SCRIPT element.
FragmentListener in the HttpKernel component in Symfony 2.3.19 through 2.3.28, 2.4.9 through 2.4.10, 2.5.4 through 2.5.11, and 2.6.0 through 2.6.7, when ESI or SSI support enabled, does not check if the _controller attribute is set, which allows remote attackers to bypass URL signing and security rules by including (1) no hash or (2) an invalid hash in a request to /_fragment.
Unspecified vulnerability in Prototype JavaScript framework (prototypejs) before 1.6.0.2 allows attackers to make "cross-site ajax requests" via unknown vectors.
The Prototype (prototypejs) framework before 1.5.1 RC3 exchanges data using JavaScript Object Notation (JSON) without an associated protection scheme, which allows remote attackers to obtain the data via a web page that retrieves the data through a URL in the SRC attribute of a SCRIPT element and captures the data using other JavaScript code, aka "JavaScript Hijacking."
