CVE-2026-87110 in Ops Manager
Summary
by MITRE • 10/09/2026
An unauthenticated user with network access to the Ops Manager web port can repeatedly request monitoring endpoints that perform costly work without rate limiting. This can temporarily slow other traffic served by the same process while requests continue.

The vulnerability described constitutes a Denial of Service (DoS) condition arising from the absence of adequate input validation and resource management controls within the Ops Manager web interface. Specifically, the monitoring endpoints exposed to unauthenticated users are designed to perform computationally expensive operations without implementing rate limiting mechanisms or request throttling policies. This architectural oversight allows any external actor with basic network connectivity to the service port to initiate a high volume of requests that consume significant server resources such as CPU cycles and memory allocation. The lack of authentication requirement further exacerbates the risk, as it removes the barrier typically used to distinguish between legitimate administrative traffic and malicious exploitation attempts, thereby enabling widespread abuse by any entity on the local network or potentially over the internet if the port is exposed externally.
From a technical perspective, this flaw aligns with CWE-770: Allocation of Resources Without Limits or Throttling, which identifies scenarios where software fails to restrict resource consumption in response to input. The operational impact involves the degradation of service availability for other users and processes sharing the same server infrastructure. As an unauthenticated user repeatedly triggers these costly monitoring queries, the system's processing capacity becomes saturated, leading to increased latency and potential timeouts for legitimate administrative tasks or other critical services hosted on the Ops Manager instance. This resource exhaustion can effectively render the management interface unusable until the attack subsides or manual intervention occurs to restart the service or clear the backlog of pending requests.
This type of vulnerability is often associated with ATT&CK technique T1499: Endpoint Denial of Service, specifically under sub-techniques involving resource exhaustion through application layer attacks. The attacker leverages the legitimate functionality of the monitoring endpoints as a vector for disruption rather than attempting to exploit a traditional software bug like buffer overflow or injection. By flooding the server with valid but expensive requests, the adversary creates a state where the system is busy processing these benign-looking queries and cannot respond to other incoming connections in a timely manner. This approach is particularly effective because it does not require bypassing firewalls or exploiting complex logic flaws; it simply relies on the volume of traffic overwhelming the available computational resources.
Mitigation strategies should focus on implementing robust access control and rate limiting policies at both the application layer and network perimeter. First, all monitoring endpoints that perform heavy computations must be restricted to authenticated users with appropriate administrative privileges, ensuring that unauthenticated actors cannot trigger these operations directly. Second, even for authenticated users, strict rate limiting should be applied to prevent any single user or IP address from generating an excessive number of requests within a defined time window. Additionally, deploying Web Application Firewalls (WAF) can help identify and block patterns indicative of automated flooding attacks before they reach the application server. Regular security assessments and load testing are recommended to ensure that resource limits are appropriately configured and that the system remains resilient under high-load conditions typical in production environments.
