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.
A Local File Inclusion (LFI) vulnerability exists in the '/reinstall_extension' endpoint of the parisneo/lollms-webui application, specifically within the `name` parameter of the `@router.post("/reinstall_extension")` route. This vulnerability allows attackers to inject a malicious `name` parameter, leading to the server loading and executing arbitrary Python files from the upload directory for discussions. This issue arises due to the concatenation of `data.name` directly with `lollmsElfServer.lollms_paths.extensions_zoo_path` and its use as an argument for `ExtensionBuilder().build_extension()`. The server's handling of the `__init__.py` file in arbitrary locations, facilitated by `importlib.machinery.SourceFileLoader`, enables the execution of arbitrary code, such as command execution or creating a reverse-shell connection. This vulnerability affects the latest version of parisneo/lollms-webui and can lead to Remote Code Execution (RCE) when the application is exposed to an external endpoint or the UI, especially when bound to `0.0.0.0` or in `headless mode`. No user interaction is required for exploitation.
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.
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.
parisneo/lollms-webui version 9.6 is vulnerable to Cross-Site Scripting (XSS) and Open Redirect due to inadequate input validation and processing of SVG files during the upload process. The XSS vulnerability allows attackers to embed malicious JavaScript code within SVG files, which is executed upon rendering, leading to potential credential theft and unauthorized data access. The Open Redirect vulnerability arises from insufficient URL validation within SVG files, enabling attackers to redirect users to malicious websites, thereby exposing them to phishing attacks, malware distribution, and reputation damage. These vulnerabilities are present in the application's functionality to send files to the AI module.
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.
A Cross-Site Request Forgery (CSRF) vulnerability exists in the profile picture upload functionality of the Lollms application, specifically in the parisneo/lollms-webui repository, affecting versions up to 7.3.0. This vulnerability allows attackers to change a victim's profile picture without their consent, potentially leading to a denial of service by overloading the filesystem with files. Additionally, this flaw can be exploited to perform a stored cross-site scripting (XSS) attack, enabling attackers to execute arbitrary JavaScript in the context of the victim's browser session. The issue is resolved in version 9.3.
