CVE-2006-2467 in WebLogic Server
Summary
by MITRE
BEA WebLogic Server 8.1 up to SP4, 7.0 up to SP6, and 6.1 up to SP7 displays the internal IP address of the WebLogic server in the WebLogic Server Administration Console, which allows remote authenticated administrators to determine the address.

The vulnerability identified as CVE-2006-2467 represents a significant information disclosure weakness in BEA WebLogic Server versions 8.1 through SP4, 7.0 through SP6, and 6.1 through SP7. This flaw manifests within the WebLogic Server Administration Console where the internal IP address of the server is inadvertently exposed to authenticated users. The vulnerability stems from insufficient input validation and output sanitization mechanisms within the administrative interface, creating an unintended information leak that can be exploited by malicious actors with valid administrative credentials.
The technical implementation of this vulnerability occurs through the WebLogic Server Administration Console's response handling mechanism. When authenticated administrators access certain administrative pages, the console includes the internal server IP address in its output, typically within error messages, configuration displays, or diagnostic information. This exposure happens because the system fails to properly sanitize or filter the output before presenting it to users, allowing the internal network address to be visible in the web interface. The vulnerability is classified under CWE-200 Information Exposure, which specifically addresses situations where sensitive information is inadvertently disclosed to unauthorized parties.
From an operational perspective, this vulnerability creates a substantial risk for organizations deploying BEA WebLogic Server in production environments. Remote authenticated administrators who possess valid administrative credentials can leverage this information to map internal network topologies and identify potential attack vectors. The disclosed internal IP addresses provide attackers with critical network intelligence that could facilitate subsequent attacks such as port scanning, service enumeration, or targeted exploitation of other vulnerabilities within the internal network. This information disclosure effectively reduces the attack surface by providing attackers with precise network mapping data that would otherwise require more sophisticated reconnaissance techniques to obtain.
The impact of this vulnerability extends beyond simple information disclosure, as it enables more sophisticated attack patterns within the context of the MITRE ATT&CK framework. Specifically, this weakness supports the initial access and reconnaissance phases by providing attackers with network topology information. The exposure of internal IP addresses can facilitate lateral movement within the network, as attackers can use this information to identify other systems that may be accessible from the compromised administrative account. Organizations may experience increased risk of privilege escalation attacks when this information is combined with other vulnerabilities, as the internal network mapping enables attackers to better understand the infrastructure layout and plan more effective attacks.
Mitigation strategies for CVE-2006-2467 should focus on implementing proper output sanitization and input validation within the WebLogic Server Administration Console. Organizations should immediately apply the applicable service packs and patches provided by BEA to address this vulnerability, as the vendor has released updates specifically designed to prevent the exposure of internal IP addresses in the administrative interface. Additionally, network segmentation and access control measures should be implemented to limit the scope of damage if the vulnerability is exploited, ensuring that administrative access is restricted to authorized personnel only. Security monitoring should be enhanced to detect unusual administrative access patterns that might indicate exploitation attempts. The implementation of web application firewalls and security configuration reviews can further reduce the risk of exploitation while maintaining the necessary administrative functionality. Organizations should also conduct regular security assessments to identify similar information disclosure vulnerabilities in other components of their web application infrastructure.
