CVE-2008-4285 in WebSphere Application Server
Summary
by MITRE
Unspecified vulnerability in the Performance Monitoring Infrastructure (PMI) feature in the Servlet Engine/Web Container component in IBM WebSphere Application Server (WAS) 6.1.x before 6.1.0.19, when a component statistic is enabled, allows attackers to cause a denial of service (daemon crash) via vectors related to "a gradual degradation in performance."

The vulnerability identified as CVE-2008-4285 resides within IBM WebSphere Application Server's Performance Monitoring Infrastructure component, specifically affecting versions 6.1.x prior to 6.1.0.19. This issue manifests in the Servlet Engine/Web Container component where performance monitoring statistics are enabled, creating a condition that can be exploited to trigger a denial of service attack. The vulnerability operates through a subtle but impactful mechanism that gradually degrades system performance until complete daemon failure occurs, making it particularly insidious as it may not be immediately apparent to administrators.
The technical flaw in this vulnerability stems from improper handling of component statistics within the PMI framework when monitoring is enabled. When performance monitoring is active, the system maintains detailed metrics about various servlet engine components and their operational characteristics. The vulnerability exploits a condition where the accumulation of these statistics, combined with specific processing patterns, leads to resource exhaustion or memory corruption that ultimately results in the daemon crashing. This degradation occurs gradually rather than instantaneously, making it difficult to detect and correlate with the attack vector.
From an operational impact perspective, this vulnerability presents a significant risk to enterprise environments relying on IBM WebSphere Application Server for critical business applications. The gradual nature of the performance degradation means that administrators may not immediately recognize the system instability, potentially allowing the attack to continue undetected for extended periods. The daemon crash that results from this vulnerability effectively renders the application server unavailable, disrupting business operations and potentially causing financial losses. The attack requires minimal resources from the attacker, making it particularly dangerous as it can be executed by anyone with access to the system.
The vulnerability aligns with CWE-400, which addresses "Uncontrolled Resource Consumption" and falls under the broader category of denial of service attacks. From an ATT&CK framework perspective, this vulnerability maps to T1499.004 for "Network Denial of Service" and potentially T1566 for initial access methods that might be used to enable the monitoring features. Organizations should implement immediate mitigations including applying the vendor patch for IBM WebSphere Application Server 6.1.0.19 or higher, disabling unnecessary performance monitoring components when not actively required, and implementing robust monitoring systems to detect performance degradation patterns. Additionally, network segmentation and access controls should be strengthened to limit potential attack vectors that could lead to enabling the vulnerable monitoring features.
