Drupal Core – Moderately Critical – Multiple Vulnerabilities – SA-CORE-2016-002

Description

Saving user accounts can sometimes grant the user all roles (User module – Drupal 7 – Moderately Critical)

A vulnerability exists in the User module, where if some specific contributed or custom code triggers a rebuild of the user profile form, a registered user can be granted all user roles on the site. This would typically result in the user gaining administrative access.

This issue is mitigated by the fact that it requires contributed or custom code that performs a form rebuild during submission of the user profile form.

Views can allow unauthorized users to see Statistics information (Views module – Drupal 8 – Less Critical)

An access bypass vulnerability exists in the Views module, where users without the “View content count” permission can see the number of hits collected by the Statistics module for results in the view.

This issue is mitigated by the fact that the view must be configured to show a “Content statistics” field, such as “Total views”, “Views today” or “Last visit”.

The same vulnerability exists in the Drupal 7 Views module (see SA-CONTRIB-2016-036).

Cisco Security Advisory 20160615-rv

Cisco Security Advisory – A vulnerability in the web interface of the Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and the Cisco RV215W Wireless-N VPN Router could allow an unauthenticated, remote attacker to execute arbitrary code as root on a targeted system. The vulnerability is due to insufficient sanitization of HTTP user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request with custom user data. An exploit could allow the attacker to execute arbitrary code with root-level privileges on the affected system, which could be leveraged to conduct further attacks. Cisco has not released software updates that address this vulnerability. Workarounds that mitigate this vulnerability are not available.

Bomgar Remote Support Unauthenticated Code Execution

This Metasploit module exploits a vulnerability in the Bomgar Remote Support, which deserializes user provided data using PHP’s unserialize method. By providing an specially crafted PHP serialized object, it is possible to write arbitrary data to arbitrary files. This effectively allows the execution of arbitrary PHP code in the context of the Bomgar Remote Support system user. To exploit the vulnerability, a valid Logging Session ID (LSID) is required. It consists of four key-value pairs (i. e., ‘h=[…];l=[…];m=[…];t=[…]’) and can be retrieved by an unauthenticated user at the end of the process of submitting a new issue via the ‘Issue Submission’ form. Versions before 15.1.1 are reported to be vulnerable.
