CVE-2024-5125 affects the parisneo/lollms-webui product, specifically version 9.6, where the application fails to properly neutralize input during web page generation, leading to Cross-Site Scripting (CWE-79) and Open Redirect vulnerabilities. The root cause lies in inadequate validation and sanitization of SVG files uploaded through the application's interface, which is used to send files to an AI processing module. Malicious actors can craft SVG files containing embedded JavaScript code that executes when the SVG is rendered in the victim's browser, enabling theft of session cookies, credentials, or other sensitive data, and potentially allowing unauthorized actions within the application context. Additionally, the Open Redirect vulnerability stems from insufficient URL validation within these SVG files, permitting attackers to redirect users to external malicious websites. This can facilitate phishing attacks, malware delivery, and damage to the organization's reputation. The CVSS 3.0 vector indicates the attack requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), and user interaction (UI:R), with impacts on confidentiality (C:L), integrity (I:H), and availability (A:H). Although no public exploits are reported yet, the vulnerability's nature and impact warrant urgent attention. The vulnerability affects the web UI component handling file uploads, a common feature in AI-related applications, increasing the risk if deployed in sensitive environments.

For European organizations, exploitation of CVE-2024-5125 could lead to significant confidentiality breaches, including theft of user credentials and sensitive data processed by the AI module. The integrity of data and system operations may be compromised due to unauthorized actions triggered by malicious scripts. Availability could also be affected if attackers disrupt service or manipulate the application workflow. The Open Redirect vulnerability increases the risk of successful phishing campaigns targeting employees or customers, potentially leading to broader network compromise or financial fraud. Organizations in sectors such as finance, healthcare, and government, which may use AI web interfaces like parisneo/lollms-webui, face heightened risks due to the sensitivity of their data and regulatory requirements under GDPR. The reputational damage from successful attacks could also have long-term business impacts. Given the local access requirement but no need for authentication, insider threats or compromised internal systems could facilitate exploitation. The lack of known exploits in the wild currently provides a window for proactive mitigation before widespread attacks occur.

European organizations should immediately review their deployment of parisneo/lollms-webui, especially version 9.6 or earlier, and apply any available patches or updates from the vendor once released. In the absence of patches, implement strict input validation and sanitization on the server side for all uploaded SVG files, including disabling or filtering out embedded scripts and suspicious URL redirects within SVG content. Employ Content Security Policy (CSP) headers to restrict script execution contexts and prevent inline script execution from untrusted sources. Limit file upload permissions to trusted users and monitor upload activity for anomalous behavior. Conduct regular security assessments and penetration tests focusing on file upload functionalities. Educate users about the risks of interacting with untrusted SVG files and suspicious redirects. Network segmentation and application-layer firewalls can help contain potential exploitation attempts. Finally, maintain robust logging and alerting mechanisms to detect exploitation attempts early.
