CVE-2026-11796 in Asset Suite
Summary
by MITRE • 09/29/2026
Asset Suite allows unauthenticated users to access PropertiesReloadServlet, CacheFlushServlet, MetadataCacheFlushServlet and ResourceBundleReloadServlet, which could result in denial-of-service conditions affecting application availability. These servlets are designed to perform specific functions within production environment depending on how the Asset Suite application is configured.

The vulnerability identified involves a critical misconfiguration or insufficient access control mechanism within the Asset Suite software suite, specifically targeting several administrative and maintenance-oriented JavaServer Pages (JSP) servlets: PropertiesReloadServlet, CacheFlushServlet, MetadataCacheFlushServlet, and ResourceBundleReloadServlet. These components are integral to the dynamic management of application state in production environments, allowing administrators to refresh configuration properties without restarting the entire service or clear cached data to ensure consistency after updates. However, the absence of proper authentication checks on these endpoints allows unauthenticated external actors to invoke them directly via HTTP requests. This lack of authorization enforcement represents a significant deviation from secure design principles, as it exposes sensitive operational controls to any user with network connectivity to the application server, regardless of their privilege level or intent.
From a technical perspective, this flaw constitutes an unauthorized access vulnerability where critical system functions are exposed without requiring valid credentials. The specific servlets mentioned handle resource-intensive operations such as reloading configuration files from disk and purging in-memory caches. When triggered by malicious actors, these actions can be executed repeatedly at high frequency or with malformed inputs to exhaust server resources. For instance, flushing metadata caches may force the application to re-query databases for every subsequent request, leading to severe performance degradation. Similarly, reloading property bundles while under heavy load can cause thread contention and memory spikes within the Java Virtual Machine (JVM). This behavior aligns closely with Common Weakness Enumeration (CWE) category CWE-284: Improper Access Control, as well as CWE-732: Incorrect Permission Assignment for Critical Resource. The vulnerability enables an attacker to disrupt normal operations without needing prior authentication, bypassing the primary security boundary of the application.
The operational impact of this vulnerability is primarily centered on denial-of-service (DoS) conditions that affect the availability and responsiveness of the Asset Suite application. By repeatedly invoking these servlets, an adversary can induce resource exhaustion, causing legitimate users to experience timeouts, slow page loads, or complete service unavailability. In a production environment where high uptime is critical, such disruptions can lead to significant business losses and reputational damage. Furthermore, if the underlying implementation of these servlets does not properly sanitize inputs before processing them, there may be secondary risks involving server-side request forgery (SSRF) or remote code execution through crafted property files that are loaded into memory. However, even without exploitation for arbitrary code execution, the ability to trigger resource-intensive operations unauthenticated provides a reliable vector for disrupting service continuity and testing system resilience against automated attacks.
To mitigate this risk, immediate remediation steps should focus on enforcing strict access controls on all administrative servlets within the Asset Suite deployment. Access to PropertiesReloadServlet, CacheFlushServlet, MetadataCacheFlushServlet, and ResourceBundleReloadServlet must be restricted exclusively to authenticated users with specific administrative roles. This can be achieved by updating the web application security constraints in the deployment descriptor (web.xml) or equivalent configuration files to require valid session tokens or HTTP authentication headers for these endpoints. Additionally, implementing IP whitelisting at the network level provides an extra layer of defense by limiting access to known management subnets. From a defensive posture perspective, this vulnerability maps to MITRE ATT&CK technique T1499: Endpoint Denial of Service, as it involves using system resources to degrade service availability. Security teams should also audit other administrative endpoints for similar misconfigurations and ensure that security patches provided by the vendor are applied promptly to address these access control gaps permanently.
