CVE-2026-92153— F´: Arbitrary File Write in Svc::FileUplink via attacker-controlled StartPacket.destinationPath

Quick assessment

Affected
nasa fprime
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

F´（F Prime）是一个用于开发和部署航天飞行及其他嵌入式软件应用的框架。在 4.3.0 版本之前，Svc::FileUplink 组件在处理 Fw::FilePacket::StartPacket 消息的目的地路径时，存在安全漏洞：FileUplink 会直接复制由数据包控制的 destinationPath，并在未经过规范化处理或未限制到指定上传目录的情况下，直接以写入方式打开该路径。当具备发送文件上行数据包能力的对等端提供绝对路径、包含路径遍历序列，或其他由攻击者控制的、可写入的目的地路径时，攻击者可以在

Vulnerability Title
F´: Arbitrary File Write in Svc::FileUplink via attacker-controlled StartPacket.destinationPath
Source: CVE Program / CVE List V5
Vulnerability Description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. 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.
