CVE-2014-6276 in Roundup
Summary
by MITRE
schema.py in Roundup before 1.5.1 does not properly limit attributes included in default user permissions, which might allow remote authenticated users to obtain sensitive user information by viewing user details.

The vulnerability identified as CVE-2014-6276 resides within the schema.py component of Roundup issue tracking system versions prior to 1.5.1. This flaw represents a critical access control weakness that undermines the system's ability to properly enforce user permissions and protect sensitive information. The vulnerability specifically affects how the system handles attribute limitations in default user permissions, creating an avenue for unauthorized information disclosure.
Roundup is a widely-used open source issue tracking and project management system that employs a flexible permission model to control access to various system resources and user data. The schema.py file serves as a crucial component in defining the default permissions and access controls for different user roles within the system. When this component fails to properly limit attributes included in default user permissions, it creates a scenario where authenticated users can potentially access user details that should be restricted to administrators or specific privileged roles.
The technical nature of this vulnerability stems from insufficient input validation and access control enforcement within the permission system. Attackers who have authenticated access to the Roundup system can exploit this flaw by crafting specific requests that bypass the normal attribute filtering mechanisms. This allows them to view user information that would typically be hidden or restricted based on the user's role and permissions level. The vulnerability essentially creates a path for privilege escalation through information disclosure rather than direct privilege manipulation.
The operational impact of CVE-2014-6276 extends beyond simple information disclosure, as it can enable attackers to gather intelligence about system users and potentially identify vulnerabilities in user accounts. This information can be leveraged for further attacks including social engineering, credential harvesting, or targeted attacks against specific user accounts. The vulnerability affects any authenticated user within the system, making it particularly dangerous as it can be exploited by insiders or compromised accounts. Organizations using vulnerable versions of Roundup face significant risk to user privacy and system security.
This vulnerability aligns with CWE-200, which addresses "Information Exposure," and represents a specific instance of improper access control where attribute-level permissions are not properly enforced. From an ATT&CK framework perspective, this vulnerability maps to T1068, which involves the exploitation of remote services or applications to gain unauthorized access. The flaw also demonstrates characteristics of T1210, involving exploitation of remote services for privilege escalation through information gathering.
Organizations affected by CVE-2014-6276 should immediately upgrade to Roundup version 1.5.1 or later, which contains the necessary patches to properly enforce attribute limitations in default user permissions. System administrators should conduct thorough security reviews of existing user permissions and access controls, particularly focusing on attribute-level restrictions. Additional mitigations include implementing network segmentation to limit access to Roundup systems, monitoring for suspicious access patterns, and conducting regular security audits of permission configurations. The vulnerability underscores the importance of proper access control implementation and attribute-based security enforcement in web applications.
