Prior to 4.3.0, Svc::FileUplink handling of Fw::FilePacket::StartPacket destination paths FileUplink copies the packet-controlled destinationPath and opens it for writing without canonicalization or confinement to an upload directory. When a peer able to send file-uplink packets supplies an absolute, traversing, or otherwise attacker-selected writable destination path, files can be created or overwritten at attacker-selected writable filesystem locations, affecting integrity and potentially availability. This issue is fixed in version 4.3.0.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","cwes":["CWE-22","CWE-73"],"vendors":[],"products":[],"references":[{"url":"https://github.com/nasa/fprime/commit/4c8b9c0b8692b0d47cbd5f2ccec61c74aa02b893","tags":[]},{"url":"https://github.com/nasa/fprime/pull/5320","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.3.0","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv","tags":[]}],"exploitRefs":[{"url":"https://github.com/nasa/fprime/commit/4c8b9c0b8692b0d47cbd5f2ccec61c74aa02b893","tags":[]},{"url":"https://github.com/nasa/fprime/pull/5320","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.3.0","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-5rfj-hw2g-vwmv","tags":[]}],"hasPoc":true,"ai":null}
