CVE-2024-33859 is a stored cross-site scripting (XSS) vulnerability identified in Logpoint versions before 7.4.0. The vulnerability occurs because the application fails to properly escape HTML content embedded within logs when rendering the 'Interesting Field' in the Web UI. Attackers can inject malicious HTML or JavaScript code into log entries, which, when viewed by a user in the Web UI, executes in the context of that user's browser session. This can lead to unauthorized actions such as session hijacking, credential theft, or manipulation of the UI to mislead users. The vulnerability does not require any privileges or authentication to exploit, but user interaction is necessary to trigger the malicious payload by viewing the affected UI component. The CVSS v3.1 score of 6.1 reflects a medium severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and impacts on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). No public exploits have been reported to date. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation leading to XSS. This vulnerability is significant because Logpoint is a widely used SIEM platform, and exploitation could allow attackers to compromise the security monitoring environment or steal sensitive information from administrators. The fix involves proper escaping or sanitization of HTML content in the UI to prevent script execution. Organizations should upgrade to Logpoint 7.4.0 or later once available or apply any interim mitigations recommended by the vendor.

The primary impact of CVE-2024-33859 is on the confidentiality and integrity of data within the Logpoint SIEM environment. Successful exploitation allows attackers to execute arbitrary scripts in the context of the victim's browser, potentially leading to session hijacking, theft of authentication tokens, or manipulation of the UI to display misleading information. This can undermine trust in security monitoring data and may allow attackers to conceal their activities or escalate privileges. Although availability is not directly affected, the indirect consequences of compromised SIEM data integrity can be severe, including delayed detection of attacks or false security alerts. Organizations relying on Logpoint for centralized log analysis and incident response could face increased risk of targeted attacks against their security infrastructure. The vulnerability's medium severity and requirement for user interaction reduce the likelihood of widespread automated exploitation, but targeted attacks against security teams remain a concern. The absence of known exploits in the wild suggests limited current risk but underscores the need for proactive mitigation.

To mitigate CVE-2024-33859, organizations should prioritize upgrading Logpoint to version 7.4.0 or later, where the vulnerability is addressed by proper escaping of HTML content in the 'Interesting Field' Web UI. Until an official patch is available, administrators can implement the following specific measures: 1) Restrict access to the Logpoint Web UI to trusted personnel only, minimizing exposure to potential malicious log entries. 2) Implement strict input validation and sanitization on log sources where possible to prevent injection of malicious HTML or scripts into logs. 3) Educate users to avoid clicking or interacting with suspicious log entries that may contain unexpected content. 4) Monitor logs for unusual or suspicious entries containing HTML or script tags that could indicate attempted exploitation. 5) Employ Content Security Policy (CSP) headers on the Logpoint Web UI to limit the execution of unauthorized scripts. 6) Regularly review and audit user roles and permissions to reduce the risk of privilege escalation. These targeted mitigations complement general security best practices and help reduce the attack surface until the vendor patch is applied.
