CVE-2012-5930 in NetIQ
Summary
by MITRE
The pa_modify_accounts function in auth.dll in unifid.exe in NetIQ Privileged User Manager 2.3.x before 2.3.1 HF2 does not require authentication for the modifyAccounts method, which allows remote attackers to change the passwords of administrative accounts via a crafted application/x-amf request.

The vulnerability identified as CVE-2012-5930 represents a critical authentication bypass flaw in NetIQ Privileged User Manager 2.3.x versions prior to 2.3.1 HF2. This issue resides within the pa_modify_accounts function located in the auth.dll component of the unifid.exe service, which is responsible for managing privileged user accounts within enterprise environments. The flaw stems from improper access control implementation where the modifyAccounts method fails to enforce necessary authentication checks, creating a significant security weakness that directly impacts privileged account management systems.
The technical exploitation of this vulnerability occurs through crafted application/x-amf requests that can be transmitted over network connections to the affected service. This method of attack leverages the Action Message Format protocol which is commonly used for communication between client applications and remote services in enterprise environments. Attackers can remotely submit malicious requests without requiring valid credentials, effectively bypassing the authentication mechanism that should protect administrative account modifications. The vulnerability specifically affects the pa_modify_accounts function within the auth.dll module, which handles account modification operations and should normally require proper authentication before allowing changes to administrative user credentials.
The operational impact of this vulnerability is severe and far-reaching within enterprise security infrastructures. Remote attackers who can reach the affected NetIQ Privileged User Manager service can immediately escalate their privileges by modifying administrative account passwords, potentially gaining full control over privileged user accounts. This creates a direct path to compromise critical enterprise systems where privileged accounts are used for administrative tasks, system maintenance, and access to sensitive data repositories. The vulnerability essentially allows attackers to undermine the fundamental security principle of least privilege by enabling unauthorized modifications to accounts that should be protected with strong authentication mechanisms. Organizations relying on this privileged access management solution face significant risk of unauthorized access to their most sensitive systems and data.
From a cybersecurity framework perspective, this vulnerability maps directly to CWE-287 which describes improper authentication issues, and aligns with ATT&CK technique T1078 for Valid Accounts and T1566 for Phishing, as the exploitation allows for account compromise without requiring legitimate credentials. The flaw demonstrates poor input validation and access control implementation, where the system fails to properly verify caller identity before performing sensitive operations. Organizations should immediately implement mitigations including patching to version 2.3.1 HF2 or later, implementing network segmentation to restrict access to the affected service, and monitoring for suspicious authentication attempts. Additional protective measures include deploying network access controls, enabling logging and monitoring of privileged account modifications, and conducting regular security assessments of privileged access management systems. The vulnerability underscores the critical importance of proper authentication mechanisms in privileged account management systems and the potential consequences of failing to implement adequate access controls for administrative functions.
