Unauthenticated arbitrary file write via GraphQL mutations
Published Sep 30, 2022 · Updated Aug 3, 2024
Path traversal in SonicJS 0.6.0 and earlier allows remote attackers to write or delete arbitrary files through unauthenticated GraphQL mutations. The fileCreate and fileUpdate resolvers pass attacker-controlled filePath and fileContent values to fileService.writeFile, which joins the path to the application root and writes it without traversal validation. Network access to the GraphQL endpoint is sufficient; overwriting a loaded service file enables code execution after application restart.
