Prior to 4.2.0, Fw::FilePacket deserialization used by Svc::FileUplink is vulnerable because Header deserialization casts the byte to the Type enum without validating its range and FilePacket::fromSerialBuffer reaches a default FW_ASSERT. When a network file packet contains an unknown file-packet type byte, the assertion aborts or resets the default Ref application process, causing denial of service. This issue is fixed in version 4.2.0.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-617"],"vendors":[],"products":[],"references":[{"url":"https://github.com/nasa/fprime/commit/cacdd555456bd83ab395b521d56c0330470ea798","tags":[]},{"url":"https://github.com/nasa/fprime/pull/4919","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.2.0","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-3534-8qg7-6cf5","tags":[]}],"exploitRefs":[{"url":"https://github.com/nasa/fprime/commit/cacdd555456bd83ab395b521d56c0330470ea798","tags":[]},{"url":"https://github.com/nasa/fprime/pull/4919","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.2.0","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-3534-8qg7-6cf5","tags":[]}],"hasPoc":true,"ai":null}
