CVE-2003-1463 in Webadmin
Summary
by MITRE
Absolute path traversal vulnerability in Alt-N Technologies WebAdmin 2.0.0 through 2.0.2 allows remote attackers with administrator privileges to (1) determine the installation path by reading the contents of the Name parameter in a link, and (2) read arbitrary files via an absolute path in the Name parameter.

The CVE-2003-1463 vulnerability represents a critical absolute path traversal flaw in Alt-N Technologies WebAdmin versions 2.0.0 through 2.0.2, demonstrating a fundamental weakness in input validation and file access controls. This vulnerability operates within the context of a web-based administration interface that processes user-supplied parameters without proper sanitization, creating an attack surface where malicious actors can exploit the system's trust in user input. The flaw specifically manifests in how the application handles the Name parameter within links, allowing unauthorized access to system resources that should remain protected. The vulnerability is particularly dangerous because it requires only administrator privileges to exploit, suggesting that the attack vector targets a system that already has elevated access rights, making the impact more severe than typical path traversal vulnerabilities.
The technical implementation of this vulnerability stems from improper validation of the Name parameter in web requests, where the application directly uses user-supplied absolute paths without adequate sanitization or access control checks. When an attacker crafts a malicious request containing an absolute path in the Name parameter, the WebAdmin application processes this input without verifying whether the requested file path is within acceptable boundaries. This creates a direct path traversal condition that allows attackers to bypass normal file access restrictions and potentially read system files that contain sensitive information such as configuration data, database credentials, or system logs. The vulnerability specifically enables two distinct attack vectors: path disclosure through reading the Name parameter contents and arbitrary file reading through absolute path manipulation, both of which fall under the CWE-22 category of Path Traversal vulnerabilities. The attack pattern aligns with techniques described in the ATT&CK framework under the T1059.007 sub-technique for Command and Scripting Interpreter, as the vulnerability enables attackers to access files that may contain system commands or configuration details necessary for further exploitation.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with critical system information that can be leveraged for subsequent attacks. An attacker who successfully exploits this vulnerability can gain knowledge of the system's installation path, which serves as a foundation for more sophisticated attacks including privilege escalation, system compromise, and data exfiltration. The ability to read arbitrary files means that attackers can potentially access sensitive configuration files, database connection strings, password files, or other system resources that could provide further access to the underlying infrastructure. This vulnerability represents a significant risk to organizations using Alt-N Technologies WebAdmin, as it essentially provides a backdoor mechanism for attackers to bypass normal security controls and access system resources that should be protected from unauthorized access. The vulnerability's exploitation requires only administrator-level access, indicating that the attack chain is relatively straightforward once an attacker has established administrative privileges, making it particularly concerning for systems where administrative accounts are compromised.
Mitigation strategies for CVE-2003-1463 should focus on implementing robust input validation and access control measures to prevent the use of absolute paths in user-supplied parameters. Organizations should immediately apply the vendor-provided patch or upgrade to a newer version of the WebAdmin software that addresses this vulnerability. The implementation of proper parameter sanitization techniques, including the removal or encoding of special characters in user inputs, can prevent malicious path traversal attempts. Additionally, implementing principle of least privilege controls ensures that even if an attacker gains administrative access, they cannot escalate privileges or access sensitive system resources beyond their intended scope. System administrators should also consider implementing web application firewalls that can detect and block suspicious path traversal patterns, and conduct regular security assessments to identify similar vulnerabilities in other applications. The remediation process should include thorough testing to ensure that the patch does not introduce compatibility issues with existing system functionality while maintaining the security improvements necessary to protect against this specific vulnerability.
