Unauthenticated payload reaching an unauthenticated-by-default MOOSDB (AV:N/PR:N/AC:L); heap OOB write yielding memory corruption and potential code execution gives C:H/I:H/A:H, same process so S:U.

3DescriptionCVE.org
MOOS-IvP through 24.8.1 contains a buffer overflow vulnerability in StringToIvPFunction() where dimension, piece, and degree counts from encoded BHV_IPF payloads are used as allocation sizes and loop bounds without validation. Attackers can supply crafted payloads with mismatched dimension values to write attacker-controlled doubles past the end of the IvPBox weight array, causing memory corruption and potential code execution.
AnalysisAI
Out-of-bounds write in MOOS-IvP through 24.8.1 allows remote attackers to corrupt memory and potentially execute code by supplying a crafted encoded BHV_IPF payload. The StringToIvPFunction() decoder reads dimension, piece, and degree counts directly from the payload and uses them as allocation sizes and loop bounds without any ceiling check, so mismatched dimension values let an attacker write attacker-controlled doubles past the end of the IvPBox weight array. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires delivering a crafted, encoded BHV_IPF/IvP-function string into a MOOS variable that MOOS-IvP (<=24.8.1) decodes with StringToIvPFunction() - in practice the attacker must be able to publish into the target's MOOSDB community or otherwise supply an IPF payload consumed by the IvP Helm. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 9.3 (AV:N/AC:L/PR:N/UI:N/VC:H/VI:H/VA:H) reflects an unauthenticated, low-complexity network vector with high impact to confidentiality, integrity and availability, consistent with a heap OOB write that can escalate to code execution. … 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 | Apply the upstream fix from MOOS-IvP PR #126 / commit 85f4653ff792b30c3ab14dc0eac0991d1405d904 (https://github.com/moos-ivp/moos-ivp/pull/126), which introduces MAX_IPF_DIMENSIONS/MAX_IPF_DEGREE ceilings, bounds the piece count by payload length, and guards IvPBox and PDMap against negative or narrowed sizes; because the references point to a PR and commit rather than a tagged release, rebuild from the patched source and confirm no released patched version tag is independently verified. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory all systems running MOOS-IvP through version 24.8.1 and isolate them from untrusted networks if operationally feasible. …
