CVE-2011-3645 in OmniDocs
Summary
by MITRE
Newgen OmniDocs allows remote attackers to bypass intended access restrictions via (1) a modified FolderRights parameter to doccab/doclist.jsp, which leads to arbitrary permission changes; or (2) a modified UserIndex parameter to doccab/userprofile/editprofile.jsp, which selects the settings page of an arbitrary user.

The vulnerability identified as CVE-2011-3645 affects Newgen OmniDocs, a document management system that provides enterprise-level content management capabilities. This security flaw represents a critical authorization bypass issue that allows remote attackers to manipulate access controls and potentially gain unauthorized administrative privileges within the system. The vulnerability stems from insufficient input validation and improper access control mechanisms within the web application's parameter handling processes.
The technical implementation of this vulnerability manifests through two distinct attack vectors that exploit parameter manipulation within the application's web interface. The first vector involves modifying the FolderRights parameter in the doccab/doclist.jsp endpoint, which enables attackers to alter permission settings for folders within the document repository. This modification allows unauthorized users to escalate their privileges and gain access to restricted content that they would normally be prohibited from viewing or modifying. The second vector targets the UserIndex parameter within doccab/userprofile/editprofile.jsp, enabling attackers to select and potentially modify the profile settings of any user account within the system, effectively allowing for arbitrary user impersonation and privilege escalation.
From an operational impact perspective, this vulnerability creates significant security risks for organizations utilizing Newgen OmniDocs. The ability to bypass access restrictions means that attackers can potentially access sensitive corporate documents, modify user permissions, and impersonate other users within the system. This vulnerability directly violates fundamental security principles of least privilege and principle of least privilege enforcement, as described in CWE-284. The remote nature of the attack means that no local system access is required, making it particularly dangerous as it can be exploited from any location with internet connectivity.
The attack vectors align with techniques documented in the MITRE ATT&CK framework under the Privilege Escalation and Credential Access tactics. Specifically, this vulnerability enables techniques such as "Exploitation for Privilege Escalation" and "Taint Data" where attackers can manipulate application parameters to gain unauthorized access. Organizations using Newgen OmniDocs are particularly vulnerable as this flaw allows attackers to modify user profiles and access control settings without proper authentication, potentially leading to complete system compromise. The vulnerability also exposes organizations to potential data breaches and unauthorized access to confidential information, as it undermines the core access control mechanisms that protect sensitive corporate data.
Mitigation strategies should focus on implementing proper input validation and parameter sanitization throughout the application's codebase. The system should enforce strict access controls and implement proper authentication checks before allowing any modifications to user permissions or access settings. Additionally, organizations should consider implementing web application firewalls and input validation mechanisms to prevent parameter manipulation attacks. Regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other components of the application. The vulnerability also highlights the importance of following secure coding practices and implementing proper authorization checks at every point where user permissions or access controls are modified, as recommended by security standards and best practices in application security development.
