MOOS-IvP pRealm through version 24.8.1 accepts unbounded REALMCAST_REQ subscriptions without validating duration or variable list limits. Attackers can register long-lived pipeways with many variables to cause pRealm to generate excessive output indefinitely, exhausting system resources.
AnalysisAI
Unauthenticated remote resource exhaustion in MOOS-IvP pRealm through version 24.8.1 allows any network-reachable attacker to register unlimited long-lived REALMCAST_REQ subscriptions with arbitrarily large variable lists, causing the pRealm process to serialize and publish excessive output on every scheduling interval until system resources are exhausted. The vulnerability stems from three absent input limits: no cap on subscription duration, no cap on variable count per subscription, and no ceiling on concurrent pipeway registrations. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network-level access to the MOOS communications bus port on the host running pRealm. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.7 with vector AV:N/AC:L/AT:N/PR:N/UI:N/VA:H is consistent with the technical description: no authentication is required (the PR comment explicitly calls the publisher 'unauthenticated'), there is no attack complexity, and the impact is purely availability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upstream fix is available via GitHub PR #132 (https://github.com/moos-ivp/moos-ivp/pull/132) and commit 8a4bb9d9154a70e769a7290ee11dde5157c03e9b; a specific released patched version number is not confirmed from available data - operators should build from the patched commit or monitor the MOOS-IvP release page at https://github.com/moos-ivp/moos-ivp for the next tagged release. … Detailed patch versions, workarounds, and compensating controls in full report. |
