The PharStreamWrapper (aka phar-stream-wrapper) package 2.x before 2.1.1 and 3.x before 3.1.1 for TYPO3 does not prevent directory traversal, which allows attackers to bypass a deserialization protection mechanism, as demonstrated by a phar:///path/bad.phar/../good.phar URL.

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

  - The PharStreamWrapper (aka phar-stream-wrapper) package 2.x before 2.1.1 and 3.x before 3.1.1 for TYPO3     does not prevent directory traversal, which allows attackers to bypass a deserialization protection     mechanism, as demonstrated by a phar:///path/bad.phar/../good.phar URL. (CVE-2019-11831)

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:

  - The PharStreamWrapper (aka phar-stream-wrapper) package 2.x before 2.1.1 and 3.x before 3.1.1 for TYPO3
    does not prevent directory traversal, which allows attackers to bypass a deserialization protection
    mechanism, as demonstrated by a phar:///path/bad.phar/../good.phar URL. (CVE-2019-11831)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true,
    {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable
    __proto__ property, it could extend the native Object.prototype. (CVE-2019-11358)

  - The PharStreamWrapper (aka phar-stream-wrapper) package 2.x before 2.1.1 and 3.x before 3.1.1 for TYPO3
    does not prevent directory traversal, which allows attackers to bypass a deserialization protection
    mechanism, as demonstrated by a phar:///path/bad.phar/../good.phar URL. (CVE-2019-11831)

Two security updates have been released for PharStreamWrapper.

Drupal Security Team reports :

CVE-2019-11831: By-passing protection of Phar Stream Wrapper Interceptor.

In order to intercept file invocations like file_exists or stat on compromised Phar archives the base name has to be determined and checked before allowing to be handled by PHP Phar stream handling. The current implementation is vulnerable to path traversal leading to scenarios where the Phar archive to be assessed is not the actual (compromised) file.

  -     [SA-CORE-2019-007](https://www.drupal.org/SA-CORE-2019-0     07)     ([CVE-2019-11831](https://nvd.nist.gov/vuln/detail/CVE-2     019-11831))

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 7.0.x prior to 7.67, 8.6.x prior to 8.6.16, or 8.7.x prior to 8.7.1. It is, therefore, affected by a path traversal vulnerability. This security release fixes third-party dependencies included in or required by Drupal core.

The current implementation is vulnerable to path traversal leading to scenarios where the Phar archive to be assessed is not the actual (compromised) file. (SA-CORE-2019-007)

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

Several security vulnerabilities have been discovered in drupal7, a PHP website platform. The vulnerabilities affect the embedded versions of the jQuery JavaScript library and the Typo3 Phar Stream Wrapper library.

CVE-2019-11358

It was discovered that the jQuery version embedded in Drupal was prone to a cross site scripting vulnerability in jQuery.extend().

For additional information, please refer to the upstream advisory at https://www.drupal.org/sa-core-2019-006.

CVE-2019-11831

It was discovered that incomplete validation in a Phar processing library embedded in Drupal, a fully-featured content management framework, could result in information disclosure.

For additional information, please refer to the upstream advisory at https://www.drupal.org/sa-core-2019-007.

For Debian 8 'Jessie', these problems have been fixed in version 7.32-1+deb8u17.

We recommend that you upgrade your drupal7 packages.
