An issue was discovered in Http Foundation in Symfony 2.7.0 through 2.7.48, 2.8.0 through 2.8.43, 3.3.0 through 3.3.17, 3.4.0 through 3.4.13, 4.0.0 through 4.0.13, and 4.1.0 through 4.1.2. It arises from support for a (legacy) IIS header that lets users override the path in the request URL via the X-Original-URL or X-Rewrite-URL HTTP request header. These headers are designed for IIS support, but it's not verified that the server is in fact running IIS, which means anybody who can send these requests to an application can trigger this. This affects \Symfony\Component\HttpFoundation\Request::prepareRequestUri() where X-Original-URL and X_REWRITE_URL are both used. The fix drops support for these methods so that they cannot be used as attack vectors such as web cache poisoning.

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

  - An issue was discovered in Http Foundation in Symfony 2.7.0 through 2.7.48, 2.8.0 through 2.8.43, 3.3.0     through 3.3.17, 3.4.0 through 3.4.13, 4.0.0 through 4.0.13, and 4.1.0 through 4.1.2. It arises from     support for a (legacy) IIS header that lets users override the path in the request URL via the X-Original-     URL or X-Rewrite-URL HTTP request header. These headers are designed for IIS support, but it's not     verified that the server is in fact running IIS, which means anybody who can send these requests to an     application can trigger this.

The fix drops support for these methods so that they     cannot be used as attack vectors such as web cache poisoning. (CVE-2018-14773)

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

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - An issue was discovered in Http Foundation in Symfony 2.7.0 through 2.7.48, 2.8.0 through 2.8.43, 3.3.0
    through 3.3.17, 3.4.0 through 3.4.13, 4.0.0 through 4.0.13, and 4.1.0 through 4.1.2. It arises from
    support for a (legacy) IIS header that lets users override the path in the request URL via the X-Original-
    URL or X-Rewrite-URL HTTP request header. These headers are designed for IIS support, but it's not
    verified that the server is in fact running IIS, which means anybody who can send these requests to an
    application can trigger this. This affects \Symfony\Component\HttpFoundation\Request::prepareRequestUri()
    where X-Original-URL and X_REWRITE_URL are both used. The fix drops support for these methods so that they
    cannot be used as attack vectors such as web cache poisoning. (CVE-2018-14773)

Web application components can sometimes rely on request HTTP headers like 'X-Original-URL' or 'X-Rewrite-URL' to override the original path of this request. Attackers can leverage this vulnerability to conduct further attacks in order to bypass restrictions or conduct cache poisonning attacks.

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: Security, bundle readers, session handling, SecurityBundle, HttpFoundation, Form, and Security\Http.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its self-reported version number, the detected Drupal application is affected by a vulnerability in Symfony library X-Original-URL and X-Rewrite-URL HTTP headers support.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

## 3.3.18 (2018-08-01)

  - security #cve-2018-14774 [HttpKernel] fix trusted     headers management in HttpCache and     InlineFragmentRenderer (nicolas-grekas)

  - security #cve-2018-14773 [HttpFoundation] Remove support     for legacy and risky HTTP headers (nicolas-grekas)

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its self-reported version, the instance of Drupal running on the remote web server is 8.x prior to 8.5.6. It is, therefore, affected by a restriction bypass vulnerability in the embedded Symfony library.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
