CVE-2026-67973: n/a
An issue in the CFDP receive path of NASA cFS v7.0.1 allows attackers to cause a Denial of Service (DoS) via replaying final CFDP PDUs.
AI Analysis
Technical Summary
This vulnerability exists in the CFDP receive path of NASA's Core Flight System (cFS) version 7.0.1. An attacker can exploit the flaw by replaying final CFDP PDUs, which leads to a denial of service condition. The CVSS v3.1 base score is 7.5, with network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability (CWE-400: Uncontrolled Resource Consumption). No patch or official remediation level has been documented as of the publication date.
Potential Impact
Successful exploitation results in denial of service, disrupting the availability of the CFDP receive path in NASA cFS v7.0.1. There is no impact on confidentiality or integrity. This could affect mission-critical operations relying on the CFDP protocol within the affected software version.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, organizations should monitor for unusual replay of CFDP PDUs and consider implementing network-level controls to limit replay attacks if feasible.
