CVE-2026-116778 - FOG：已驗證的低許可權 API 使用者可修改儲存節點並執行 root 命令

FOG 是一個免費、開源的克隆/映像/救援套件/庫存管理系統。在 1.5.10.2253 與 1.6.0-RC-1 之前，擁有 uType=1、已啟用 API、且持有使用者 API 令牌與全域 FOG API 令牌的已驗證使用者，可以使用 PUT /fog/storagenode/{id}/edit 來修改 Storage Node 的 user、pass 與 ftppath 欄位，因為 API 會驗證憑證但不強制僅限管理員角色。啟用儲存複製且有可用 Storage Node 時，FOGImageReplicator 會將這些欄位插值進 lftp 指令，該指令由 root 執行的服務透過 proc_open() 執行，使低許可權使用者能以 root 身份執行指令。此問題已於 1.5.10.2253 與 1.6.0-RC-1 版修復。

  Action	Type	Old Value	New Value
  Added	Description		FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to 1.5.10.2253 and 1.6.0-RC-1, an authenticated API-enabled user with uType=1 who possesses both the user's API token and the global FOG API token can use PUT /fog/storagenode/{id}/edit to modify Storage Node user, pass, and ftppath fields because the API validates the credentials but does not enforce an administrator-only role. With storage replication enabled and a usable Storage Node, FOGImageReplicator interpolates those fields into an lftp command executed through proc_open() by the root-running service, allowing the low-privileged user to execute commands as root. This issue is fixed in versions 1.5.10.2253 and 1.6.0-RC-1.
