parisneo/lollms-webui is vulnerable to path traversal attacks that can lead to remote code execution due to insufficient sanitization of user-supplied input in the 'Database path' and 'PDF LaTeX path' settings. An attacker can exploit this vulnerability by manipulating these settings to execute arbitrary code on the targeted server. The issue affects the latest version of the software. The vulnerability stems from the application's handling of the 'discussion_db_name' and 'pdf_latex_path' parameters, which do not properly validate file paths, allowing for directory traversal. This vulnerability can also lead to further file exposure and other attack vectors by manipulating the 'discussion_db_name' parameter.

A vulnerability in the parisneo/lollms-webui version 9.3 allows attackers to bypass intended access restrictions and execute arbitrary code. The issue arises from the application's handling of the `/execute_code` endpoint, which is intended to be blocked from external access by default. However, attackers can exploit the `/update_setting` endpoint, which lacks proper access control, to modify the `host` configuration at runtime. By changing the `host` setting to an attacker-controlled value, the restriction on the `/execute_code` endpoint can be bypassed, leading to remote code execution. This vulnerability is due to improper neutralization of special elements used in an OS command (`Improper Neutralization of Special Elements used in an OS Command`).

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.

parisneo/lollms-webui is vulnerable to path traversal and denial of service attacks due to an exposed `/select_database` endpoint in version a9d16b0. The endpoint improperly handles file paths, allowing attackers to specify absolute paths when interacting with the `DiscussionsDB` instance. This flaw enables attackers to create directories anywhere on the system where the application has permissions, potentially leading to denial of service by creating directories with names of critical files, such as HTTPS certificate files, causing server startup failures. Additionally, attackers can manipulate the database path, resulting in the loss of client data by constantly changing the file location to an attacker-controlled location, scattering the data across the filesystem and making recovery difficult.

A Server-Side Request Forgery (SSRF) vulnerability exists in the 'add_webpage' endpoint of the parisneo/lollms-webui application, affecting the latest version. The vulnerability arises because the application does not adequately validate URLs entered by users, allowing them to input arbitrary URLs, including those that target internal resources such as 'localhost' or '127.0.0.1'. This flaw enables attackers to make unauthorized requests to internal or external systems, potentially leading to access to sensitive data, service disruption, network integrity compromise, business logic manipulation, and abuse of third-party resources. The issue is critical and requires immediate attention to maintain the application's security and integrity.
