CVE-2021-35499

The Web Reporting component of TIBCO Software Inc.'s TIBCO Nimbus contains easily exploitable Stored Cross Site Scripting (XSS) vulnerabilities that allow a low privileged attacker to social engineer a legitimate user with network access to execute scripts targeting the affected system or the victim's local system. A successful attack using this vulnerability requires human interaction from a person other than the attacker. Affected releases are TIBCO Software Inc.'s TIBCO Nimbus: versions 10.4.0 and below.

Security Impact Summary

This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.0, indicating it can be exploited remotely over the network with relatively low complexity though user interaction is required requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 1 product from tibco organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2021, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For tibco's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
