CVE-2024-4839 in lollms-webui
Summary
by MITRE • 06/24/2024
A Cross-Site Request Forgery (CSRF) vulnerability exists in the 'Servers Configurations' function of the parisneo/lollms-webui, versions 9.6 to the latest. The affected functions include Elastic search Service (under construction), XTTS service, Petals service, vLLM service, and Motion Ctrl service, which lack CSRF protection. This vulnerability allows attackers to deceive users into unwittingly installing the XTTS service among other packages by submitting a malicious installation request. Successful exploitation results in attackers tricking users into performing actions without their consent.

The CVE-2024-4839 vulnerability represents a critical cross-site request forgery weakness in the parisneo/lollms-webui application, specifically within its server configuration functionalities. This vulnerability affects versions 9.6 through the latest releases and impacts multiple core services including Elastic search Service, XTTS service, Petals service, vLLM service, and Motion Ctrl service. The flaw lies in the absence of proper CSRF protection mechanisms within these administrative functions, creating a significant security gap that can be exploited by malicious actors to manipulate user sessions and execute unauthorized actions on behalf of authenticated users. The vulnerability's impact extends beyond simple data manipulation as it directly undermines the integrity of user consent and system authorization processes.
The technical implementation of this vulnerability stems from the lack of anti-CSRF tokens or similar protection mechanisms in the affected service configuration endpoints. When users navigate to the server configuration interface and attempt to install or modify services such as XTTS, the application fails to validate that the request originates from the legitimate user interface rather than a maliciously crafted request. This absence of validation creates a pathway for attackers to construct malicious web pages or exploit existing user sessions to submit unauthorized installation requests. The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery, and represents a classic example of how insufficient input validation and lack of proper session management can compromise application security. Attackers can leverage this weakness to perform unauthorized service installations, potentially leading to privilege escalation or system compromise through the installation of malicious components.
The operational impact of this vulnerability is substantial as it enables attackers to manipulate user systems without their knowledge or consent, particularly when targeting service installations that may have elevated privileges or system-level access. The ability to trick users into installing the XTTS service or other packages represents a sophisticated attack vector that can be combined with social engineering techniques to maximize exploitation success rates. This vulnerability directly violates the principle of least privilege and user consent, as legitimate users may unknowingly authorize actions that could compromise their system integrity. The attack surface is particularly concerning given that the affected services include various machine learning and artificial intelligence components that may have significant system access requirements. According to ATT&CK framework, this vulnerability maps to T1566 (Phishing) and T1078 (Valid Accounts) as attackers can exploit the CSRF weakness to leverage authenticated sessions for unauthorized service installations, potentially leading to persistent access or privilege escalation.
Organizations utilizing the parisneo/lollms-webui application must implement immediate mitigations to address this CSRF vulnerability. The primary remediation involves implementing robust anti-CSRF token mechanisms across all server configuration endpoints, ensuring that each request contains a unique, unpredictable token that validates the user's intent to perform the requested action. Additionally, implementing proper referer header validation and SameSite cookie attributes can provide additional layers of protection against cross-site request forgery attacks. The application should enforce strict session management protocols and implement proper request origin validation to prevent unauthorized service installations. Security teams should also conduct comprehensive vulnerability assessments to identify any other endpoints that may lack CSRF protection, as this represents a systemic security weakness that could affect multiple application functions. Regular security updates and patch management procedures should be implemented to ensure that such vulnerabilities are promptly addressed when they are discovered in the application's codebase.
