Title
Sage XRT Treasury, version 3, fails to properly restrict database access to authorized users, which may enable any authenticated user to gain full access to privileged database functions
Summary
Sage XRT Treasury, version 3, fails to properly restrict database access to authorized users, which may enable any authenticated user to gain full access to privileged database functions. Sage XRT Treasury is a business finance management application. Database user access privileges are determined by the USER_CODE field associated with the querying user. By modifying the USER_CODE value to match that of a privileged user, a low-privileged, authenticated user may gain privileged access to the SQL database. A remote, authenticated user can submit specially crafted SQL queries to gain privileged access to the application database.
Severity
No CVSS data available.

Title
Wowza Streaming Engine 4.5.0 Local Privilege Escalation via nssm_x64.exe
Summary
Wowza Streaming Engine 4.5.0 contains a local privilege escalation vulnerability that allows authenticated users to escalate privileges by replacing executable files due to improper file permissions granting full access to the Everyone group. Attackers can replace the nssm_x64.exe binary in the manager and engine service directories with malicious executables to execute code with LocalSystem privileges when services restart.

Title
Openstack keystone: openstack keystone: authorization bypass via improper ec2 token handling
Summary
A flaw was found in OpenStack Keystone. This vulnerability allows remote authenticated users to bypass intended authorization restrictions. This occurs because OpenStack Keystone does not properly handle EC2 (Elastic Compute Cloud) tokens when a user's role has been removed from a tenant. An attacker can leverage a token associated with a removed user role to gain unauthorized access.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
No CAPEC attack patterns related to this CWE.
