Lifecycle Timeline
2DescriptionCVE.org
A vulnerability was identified in NASA cFS up to 7.0.1. Impacted is the function OS_read of the file modules/protocol/tcp/fsw/src/sbn_tcp_if.c of the component SBN TCP Module. Such manipulation of the argument MsgSz leads to buffer overflow. The attack must be carried out from within the local network. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Buffer overflow in NASA Core Flight System (cFS) up to version 7.0.1 allows adjacent-network attackers to corrupt memory through the SBN TCP Module's OS_read function. The MsgSz argument read from incoming TCP messages is not bounds-checked before use, enabling a crafted packet to overflow an internal buffer. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be on the same local network segment as the target cFS node - internet-originated attacks are not possible given AV:A. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:A/AC:L/AT:N/PR:N/UI:N) assigns adjacent-network access with no authentication, no complexity barriers, and all three CIA impacts at Low - yielding a 5.3 base score. … 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 | No vendor-released patch has been identified at time of analysis, and NASA did not respond to coordinated disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
