Lollms Web Ui

LoLLMs WEBUI provides the Web user interface for Lord of Large Language and Multi modal Systems. A critical Server-Side Request Forgery (SSRF) vulnerability has been identified in all known existing versions of `lollms-webui`. The `@router.post("/api/proxy")` endpoint allows unauthenticated attackers to force the server into making arbitrary GET requests. This can be exploited to access internal services, scan local networks, or exfiltrate sensitive cloud metadata (e.g., AWS/GCP IAM tokens). As of time of publication, no known patched versions are available.Show less

A vulnerability in parisneo/lollms-webui v13 arises from the server's handling of multipart boundaries in file uploads. The server does not limit or validate the length of the boundary or the characters appended to it, allowing an attacker to craft requests with excessively long boundaries, leading to resource exhaustion and eventual denial of service (DoS). Despite an attempted patch in commit 483431bb, which blocked hyphen characters from being appended to the multipart boundary, the fix is insufficient. The server remains vulnerable if other characters (e.g., '4', 'a') are used instead of hyphens. This allows attackers to exploit the vulnerability using different characters, causing resource exhaustion and service unavailability.Show less

In version v12 of parisneo/lollms-webui, the 'Send file to AL' function allows uploading files with various extensions, including potentially dangerous ones like .py, .sh, .bat, and more. Attackers can exploit this by uploading files with malicious content and then using the '/open_file' API endpoint to execute these files. The vulnerability arises from the use of 'subprocess.Popen' to open files without proper validation, leading to potential remote code execution.Show less

A missing authentication check in the uninstall endpoint of parisneo/lollms-webui V13 allows attackers to perform unauthorized directory deletions. The /uninstall/{app_name} API endpoint does not call the check_access() function to verify the client_id, enabling attackers to delete directories without proper authentication.Show less

A path traversal vulnerability exists in the `install` and `uninstall` API endpoints of parisneo/lollms-webui version V12 (Strawberry). This vulnerability allows attackers to create or delete directories with arbitrary paths on the system. The issue arises due to insufficient sanitization of user-supplied input, which can be exploited to traverse directories outside the intended path.Show less

A Denial of Service (DoS) vulnerability exists in multiple file upload endpoints of parisneo/lollms-webui version V12 (Strawberry). The vulnerability can be exploited remotely via Cross-Site Request Forgery (CSRF). Despite CSRF protection preventing file uploads, the application still processes multipart boundaries, leading to resource exhaustion. By appending additional characters to the multipart boundary, an attacker can cause the server to parse each byte of the boundary, ultimately leading to service unavailability. This vulnerability is present in the `/upload_avatar`, `/upload_app`, and `/upload_logo` endpoints.Show less

A vulnerability in the `upload_app` function of parisneo/lollms-webui V12 (Strawberry) allows an attacker to delete any file or directory on the system. The function does not implement user input filtering with the `filename` value, causing a Path Traversal error.Show less

A vulnerability in the sanitize_path function in parisneo/lollms-webui v10 - latest allows an attacker to bypass path sanitization by using relative paths such as './'. This can lead to unauthorized access to directories within the personality_folder on the victim's computer.Show less

A Cross-site Scripting (XSS) vulnerability exists in the Settings page of parisneo/lollms-webui version 9.8. The vulnerability is due to the improper use of the 'v-html' directive, which inserts the content of the 'full_template' variable directly as HTML. This allows an attacker to execute malicious JavaScript code by injecting a payload into the 'System Template' input field under main configurations.Show less

parisneo/lollms-webui version V13 (feather) suffers from a Server-Side Request Forgery (SSRF) vulnerability in the `POST /api/proxy` REST API. Attackers can exploit this vulnerability to abuse the victim server's credentials to access unauthorized web resources by specifying the JSON parameter `{"url":"http://steal.target"}`. Existing security mechanisms such as `forbid_remote_access(lollmsElfServer)`, `lollmsElfServer.config.headless_server_mode`, and `check_access(lollmsElfServer, request.client_id)` do not protect against this vulnerability.Show less

parisneo/lollms-webui versions v9.9 to the latest are vulnerable to a directory listing vulnerability. An attacker can list arbitrary directories on a Windows system by sending a specially crafted HTTP request to the /open_file endpoint.Show less

A vulnerability in the `start_app_server` function of parisneo/lollms-webui V12 (Strawberry) allows for path traversal and OS command injection. The function does not properly sanitize the `app_name` parameter, enabling an attacker to upload a malicious `server.py` file and execute arbitrary code by exploiting the path traversal vulnerability.Show less

A CORS misconfiguration in parisneo/lollms-webui prior to version 10 allows attackers to steal sensitive information such as logs, browser sessions, and settings containing private API keys from other services. This vulnerability can also enable attackers to perform actions on behalf of a user, such as deleting a project or sending a message. The issue impacts the confidentiality and integrity of the information.Show less

A Cross-Site Request Forgery (CSRF) vulnerability exists in the `install_comfyui` endpoint of the `lollms_comfyui.py` file in the parisneo/lollms-webui repository, versions v9.9 to the latest. The endpoint uses the GET method without requiring a client ID, allowing an attacker to trick a victim into installing ComfyUI. If the victim's device does not have sufficient capacity, this can result in a crash.Show less

A vulnerability in parisneo/lollms-webui version 9.8 allows for a Denial of Service (DOS) attack when uploading an audio file. If an attacker appends a large number of characters to the end of a multipart boundary, the system will continuously process each character, rendering lollms-webui inaccessible. This issue is exacerbated by the lack of Cross-Site Request Forgery (CSRF) protection, enabling remote exploitation. The vulnerability leads to service disruption, resource exhaustion, and extended downtime.Show less

A Local File Inclusion vulnerability exists in parisneo/lollms-webui versions below v9.8. The vulnerability is due to unverified path concatenation in the `serve_js` function in `app.py`, which allows attackers to perform path traversal attacks. This can lead to unauthorized access to arbitrary files on the server, potentially exposing sensitive information such as private SSH keys, configuration files, and source code.Show less

In parisneo/lollms-webui version v9.8, the lollms_binding_infos is missing the client_id parameter, which leads to multiple security vulnerabilities. Specifically, the endpoints /reload_binding, /install_binding, /reinstall_binding, /unInstall_binding, /set_active_binding_settings, and /update_binding_settings are susceptible to CSRF attacks and local attacks. An attacker can exploit this vulnerability to perform unauthorized actions on the victim's machine.Show less

parisneo/lollms-webui, in its latest version, is vulnerable to remote code execution due to an insecure dependency on llama-cpp-python version llama_cpp_python-0.2.61+cpuavx2-cp311-cp311-manylinux_2_31_x86_64. The vulnerability arises from the application's 'binding_zoo' feature, which allows attackers to upload and interact with a malicious model file hosted on hugging-face, leading to remote code execution. The issue is linked to a known vulnerability in llama-cpp-python, CVE-2024-34359, which has not been patched in lollms-webui as of commit b454f40a. The vulnerability is exploitable through the application's handling of model files in the 'bindings_zoo' feature, specifically when processing gguf format model files.Show less

An absolute path traversal vulnerability exists in parisneo/lollms-webui v9.6, specifically in the `open_file` endpoint of `lollms_advanced.py`. The `sanitize_path` function with `allow_absolute_path=True` allows an attacker to access arbitrary files and directories on a Windows system. This vulnerability can be exploited to read any file and list arbitrary directories on the affected system.Show less

A Cross-site Scripting (XSS) vulnerability exists in the chat functionality of parisneo/lollms-webui in the latest version. This vulnerability allows an attacker to inject malicious scripts via chat messages, which are then executed in the context of the user's browser.Show less
