Lifecycle Timeline
3DescriptionCVE.org
MOOS-IvP pMarineViewer through 24.8.1 fails to limit the number of tracked node identities from NODE_REPORT messages, allowing attackers to exhaust memory by supplying unbounded distinct node names. Attackers can publish crafted NODE_REPORT data to cause memory exhaustion and stall the operator display without authentication.
AnalysisAI
Unbounded memory consumption in MOOS-IvP pMarineViewer through version 24.8.1 allows unauthenticated network attackers to exhaust the operator display process by flooding it with NODE_REPORT messages carrying arbitrary distinct node names. The ContactLedger class allocates a new tracking entry for every unique vessel name it encounters without enforcing any cap, making the ledger - and everything that iterates it - grow without limit. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network-level access to the MOOS publish-subscribe database (MOOSDB), which acts as the message broker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.7 (AV:N/AC:L/AT:N/PR:N/UI:N/VA:H) accurately characterises the availability-only impact: any network peer on the MOOS communication bus can trigger the condition without credentials. … 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 | The primary fix is to apply the upstream patch from GitHub PR #134 (commit 4d8d0693d3f8bf8907dc0aed04ea488d85af9f22), which caps ContactLedger at 200 distinct contacts by default and allows operators to call setMaxContacts() to tune the limit for their mission profile. … Detailed patch versions, workarounds, and compensating controls in full report. |
