An issue was discovered in network-manager-applet (aka network-manager-gnome) in Ubuntu 12.04 LTS, 14.04 LTS, 16.04 LTS, and 16.10. A local attacker could use this issue at the default Ubuntu login screen to access local files and execute arbitrary commands as the lightdm user. The exploitation requires physical access to the locked computer and the Wi-Fi must be turned on. An access point that lets you use a certificate to login is required as well, but it's easy to create one. Then, it's possible to open a nautilus window and browse directories. One also can open some applications such as Firefox, which is useful for downloading malicious binaries.Show less

A vulnerability in the web-based GUI of Cisco UCS Director 6.0.0.0 and 6.0.0.1 could allow an authenticated, local attacker to execute arbitrary workflow items with just an end-user profile, a Privilege Escalation Vulnerability. The vulnerability is due to improper role-based access control (RBAC) after the Developer Menu is enabled in Cisco UCS Director. An attacker could exploit this vulnerability by enabling Developer Mode for his/her user profile with an end-user profile and then adding new catalogs with arbitrary workflow items to his/her profile. An exploit could allow an attacker to perform any actions defined by these workflow items, including actions affecting other tenants. Cisco Bug IDs: CSCvb64765.Show less

mod_lua.c in the mod_lua module in the Apache HTTP Server 2.3.x and 2.4.x through 2.4.10 does not support an httpd configuration in which the same Lua authorization provider is used with different arguments within different contexts, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging multiple Require directives, as demonstrated by a configuration that specifies authorization for one group to access a certain directory, and authorization for a second group to access a second directory.Show less
