CVE-2007-0424 in WebLogic Server
Summary
by MITRE
Unspecified vulnerability in the BEA WebLogic Server proxy plug-in for Netscape Enterprise Server before September 2006 for Netscape Enterprise Server allow remote attackers to cause a denial of service via certain requests that trigger errors that lead to a server being marked as unavailable, hosting web server failure, or CPU consumption.

The vulnerability identified as CVE-2007-0424 affects the BEA WebLogic Server proxy plug-in implementation within Netscape Enterprise Server environments prior to the September 2006 security update cycle. This issue represents a classic denial of service weakness that exploits error handling mechanisms within the proxy component, specifically targeting the integration between WebLogic Server and Netscape Enterprise Server. The vulnerability manifests when remote attackers submit carefully crafted requests that trigger internal error conditions within the proxy plug-in, ultimately leading to cascading system failures that compromise availability and operational integrity.
The technical flaw resides in the inadequate error handling and resource management within the WebLogic Server proxy plug-in module. When processing certain malformed or unexpected requests, the plug-in fails to properly validate input parameters or handle exceptional conditions, causing the system to enter unstable states. This improper error propagation can result in the server being marked as unavailable by the proxy infrastructure, leading to complete hosting web server failure or excessive cpu consumption that degrades overall system performance. The vulnerability operates at the application layer and leverages protocol-level weaknesses in request processing, making it particularly dangerous as it can be exploited without requiring authentication or specialized privileges.
The operational impact of this vulnerability extends beyond simple service disruption to encompass broader system reliability concerns within enterprise web infrastructure deployments. Organizations utilizing BEA WebLogic Server in conjunction with Netscape Enterprise Server face significant risks including unauthorized service disruption, potential data loss due to server instability, and increased administrative overhead for system recovery operations. The vulnerability's exploitation can lead to complete unavailability of web applications hosted through the affected proxy configuration, affecting business continuity and potentially exposing sensitive data processing environments to additional security risks. Network administrators must consider the cascading effects of such failures, as proxy server malfunctions can propagate throughout complex enterprise architectures.
Mitigation strategies for CVE-2007-0424 require immediate implementation of the vendor-provided security patches released in September 2006 for the BEA WebLogic Server proxy plug-in. Organizations should also implement network-level monitoring to detect unusual request patterns that may indicate exploitation attempts, while establishing robust error handling procedures within their web application frameworks. The vulnerability aligns with CWE-400, which categorizes unrestricted resource consumption as a significant security concern, and corresponds to ATT&CK technique T1499.004 for network denial of service attacks. System administrators should conduct comprehensive vulnerability assessments to identify all affected proxy configurations and implement proper input validation controls to prevent similar issues in other components of their web infrastructure stack.
