CVE-2015-7464 in Jazz Reporting Service
Summary
by MITRE
Report Builder in IBM Jazz Reporting Service (JRS) 5.x before 5.0.2-Rational-CLM-ifix011 and 6.0 before 6.0.0-Rational-CLM-ifix005 allows remote attackers to cause a denial of service (Report Builder server outage) via a crafted request to a Report Builder instance URL.

The vulnerability identified as CVE-2015-7464 affects IBM Jazz Reporting Service (JRS) versions 5.x prior to 5.0.2-Rational-CLM-ifix011 and 6.0 prior to 6.0.0-Rational-CLM-ifix005, specifically targeting the Report Builder component within this enterprise reporting platform. This issue represents a critical denial of service vulnerability that can be exploited by remote attackers to completely disrupt the availability of the reporting service. The vulnerability stems from inadequate input validation mechanisms within the Report Builder instance URL handling functionality, allowing malicious actors to craft specially formatted requests that can trigger system instability and subsequent service outages.
The technical flaw manifests as a lack of proper request sanitization and validation within the Report Builder component, which processes incoming HTTP requests without sufficient checks on the URL parameters or request structure. When a crafted malicious request is submitted to the Report Builder instance URL, the system fails to properly handle the malformed input and subsequently crashes or becomes unresponsive, leading to complete service disruption. This vulnerability operates at the application layer and can be exploited through standard network communication channels without requiring authentication or privileged access, making it particularly dangerous in enterprise environments where continuous reporting availability is critical for business operations.
The operational impact of this vulnerability extends beyond simple service interruption, as it can severely affect business continuity and operational efficiency within organizations using IBM Rational Collaborative Lifecycle Management solutions. When the Report Builder server becomes unavailable, users lose access to critical reporting capabilities that may include project status reports, resource utilization metrics, and compliance documentation that are essential for decision-making processes. The vulnerability affects organizations that rely on automated reporting schedules and real-time data visualization, potentially causing cascading effects throughout the development lifecycle management processes that depend on these reporting services. The attack surface is particularly broad as the vulnerability affects multiple versions of the IBM Jazz Reporting Service, increasing the potential impact across various enterprise deployments.
Organizations affected by this vulnerability should immediately implement the vendor-provided security patches and fixes, specifically the IBM Rational-CLM-ifix011 for version 5.0.2 and the IBM Rational-CLM-ifix005 for version 6.0.0, which address the input validation weaknesses in the Report Builder component. Network-level mitigations such as implementing web application firewalls and access control lists can provide temporary protection while patches are deployed, though these measures are not comprehensive solutions. Additionally, organizations should consider implementing monitoring and alerting mechanisms to detect unusual request patterns that may indicate exploitation attempts, as the vulnerability can be triggered through automated scanning tools. The vulnerability aligns with CWE-400, which describes unrestricted input validation, and maps to ATT&CK technique T1499.004 for network denial of service attacks, emphasizing the importance of proper input validation and robust error handling in enterprise applications to prevent such disruptions.
