In Symfony before 2.7.51, 2.8.x before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7, HTTP Methods provided as verbs or using the override header may be treated as trusted input, but they are not validated, possibly causing SQL injection or XSS. This is related to symfony/http-foundation.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    (CVE-2019-10913)

Note that Nessus relies on the presence of the package as reported by the vendor.

Multiple vulnerabilities were discovered in the Symfony PHP framework which could lead to cache bypass, authentication bypass, information disclosure, open redirect, cross-site request forgery, deletion of arbitrary files, or arbitrary code execution.

Several security vulnerabilities have been discovered in symfony, a PHP web application framework. Numerous symfony components are affected: Framework Bundle, Dependency Injection, Security, HttpFoundation

CVE-2019-10909

Validation messages were not escaped when using the form theme of the PHP templating engine which, when validation messages may contain user input, could result in an XSS.

CVE-2019-10910

Service IDs derived from unfiltered user input could result in the execution of any arbitrary code, resulting in possible remote code execution.

For further information, see the upstream advisory at https://symfony.com/blog/cve-2019-10910-check-service-ids-ar e-valid

CVE-2019-10911

This fixes situations where part of an expiry time in a cookie could be considered part of the username, or part of the username could be considered part of the expiry time. An attacker could modify the remember me cookie and authenticate as a different user. This attack is only possible if remember me functionality is enabled and the two users share a password hash or the password hashes (e.g.
UserInterface::getPassword()) are null for all users (which is valid if passwords are checked by an external system, e.g. an SSO).

For further information, see the upstream advisory at

https://symfony.com/blog/cve-2019-10911-add-a-separator-in-the-remembe r-me-cookie-hash

CVE-2019-10913

HTTP methods, from either the HTTP method itself or using the X-Http-Method-Override header were previously returned as the method in question without validation being done on the string, meaning that they could be used in dangerous contexts when left unescaped.

For further information, see the upstream advisory at

https://symfony.com/blog/cve-2019-10913-reject-invalid-http-method-ove rrides

For Debian 8 'Jessie', these problems have been fixed in version 2.3.21+dfsg-4+deb8u5.

We recommend that you upgrade your symfony packages.
