CVE-2004-2748 in WebTrends
Summary
by MITRE
viewreport.pl in NetIQ WebTrends Reporting Center Enterprise Edition 6.1a allows remote attackers to determine the installation path via an invalid profileid parameter, which leaks the pathname in an error message.

The vulnerability identified as CVE-2004-2748 affects the NetIQ WebTrends Reporting Center Enterprise Edition version 6.1a, specifically within the viewreport.pl script. This represents a classic information disclosure weakness that occurs when the application fails to properly validate user input parameters. The flaw manifests when an attacker submits an invalid profileid parameter to the viewreport.pl endpoint, causing the system to return an error message that contains the absolute installation path of the web application. This type of vulnerability falls under the category of CWE-200 Information Exposure, where sensitive system information is inadvertently revealed to unauthorized users through error handling mechanisms.
The technical exploitation of this vulnerability demonstrates poor input validation and error handling practices within the web application. When the viewreport.pl script processes an invalid profileid parameter, it does not sanitize or properly validate the input before using it in error generation routines. Instead of returning a generic error message, the application reveals the complete file path where the software is installed on the server. This information leakage creates a significant security risk as it provides attackers with crucial system topology details that can be leveraged for subsequent attacks. The vulnerability is classified as a path traversal information disclosure issue that directly violates secure coding principles and can be categorized under ATT&CK technique T1083 - File and Directory Discovery.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with critical infrastructure details that can be used to plan more sophisticated attacks. Once an attacker knows the installation path, they can potentially map the entire directory structure, identify other potentially vulnerable components, and develop targeted exploitation strategies. This information can be particularly valuable for attackers planning directory traversal attacks, local file inclusion vulnerabilities, or other path-based exploits that rely on knowing the exact server path structure. The vulnerability also represents a significant risk to the organization's attack surface, as it provides an easy method for threat actors to gather reconnaissance information without requiring any special privileges or advanced techniques.
Organizations affected by this vulnerability should implement immediate mitigations including input validation improvements, proper error handling mechanisms, and comprehensive security hardening of the web application. The most effective remediation involves modifying the viewreport.pl script to sanitize all user inputs and implement generic error messages that do not reveal system path information. Additionally, organizations should consider implementing web application firewalls, input validation filters, and regular security assessments to prevent similar issues. This vulnerability highlights the importance of following secure coding practices and adhering to standards such as the OWASP Top Ten, which emphasizes the critical nature of proper error handling and input validation in preventing information disclosure attacks. The incident also underscores the necessity of conducting regular security audits and penetration testing to identify and remediate such exposure vulnerabilities before they can be exploited by malicious actors.
