The vulnerability identified as CVE-2005-0542 resides within the cyclades alterpath manager console server version 1.2.1, specifically in the saveuser.do component. This flaw represents a critical privilege escalation vulnerability that allows local attackers to elevate their system privileges by manipulating a single parameter within the application's user management functionality. The vulnerability stems from insufficient input validation and access control mechanisms within the application's administrative user creation process, creating a pathway for unauthorized privilege elevation.
The technical implementation of this vulnerability occurs through the manipulation of the adminuser parameter within the saveuser.do script. When a local user submits a request to create a new user account through this interface, they can set the adminuser parameter to true, effectively bypassing the normal administrative user creation restrictions. This parameter manipulation allows the attacker to create a new administrative user account with elevated privileges, thereby gaining unauthorized access to the system with administrative capabilities. The flaw exists due to the absence of proper authentication checks and authorization validation before processing the administrative user creation request, making it a classic example of insecure direct object reference vulnerability.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it provides attackers with complete administrative control over the affected system. Once an attacker successfully exploits this vulnerability, they can perform any action within the system that an authorized administrator could perform, including modifying system configurations, accessing sensitive data, creating additional administrative accounts, and potentially establishing persistent access. This vulnerability is particularly dangerous in environments where the console server is used for critical infrastructure management, as it allows attackers to compromise the entire management interface and potentially gain access to underlying systems.
The vulnerability aligns with CWE-284, which describes improper access control mechanisms, and demonstrates characteristics consistent with ATT&CK technique T1068, which involves privilege escalation through local exploitation. Organizations using cyclades alterpath manager console server 1.2.1 are particularly at risk, as this vulnerability requires no specialized tools or network access to exploit, making it highly attractive to attackers who may already have local system access. The lack of proper parameter validation and the absence of privilege verification during user creation processes creates a fundamental security flaw that violates basic security principles of least privilege and proper access control enforcement.
Mitigation strategies for this vulnerability should include immediate patching of the affected console server version to address the parameter validation flaw. System administrators should also implement additional security controls such as monitoring for unusual user creation patterns and implementing proper access controls for administrative functions. The recommended approach involves disabling the vulnerable saveuser.do functionality until a patched version is deployed, while also reviewing and strengthening the overall access control mechanisms within the application. Organizations should conduct comprehensive security assessments of similar applications to identify and remediate comparable vulnerabilities that may exist in other components of their infrastructure.
