Consequently, this can cause the application to access files or directories outside of the restricted directory, potentially leading to sensitive information exposure, system compromise, or data leakage.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3414888116\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Here is a conceptual example of a HTTP request that could exploit this vulnerability:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/file?filename=..\/..\/..\/etc\/passwd HTTP\/1.1\nHost: vulnerable-clever.com<\/code><\/pre>\n<p>In this example, the attacker attempts to traverse the file system to the &#8220;\/etc\/passwd&#8221; file, which could reveal sensitive information about the system&#8217;s users.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>Users of the affected versions of LambertGroup CLEVER are strongly advised to apply the vendor-supplied patch as soon as possible. As a temporary mitigation measure, users can make use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to protect against potential exploitation of this vulnerability. However, these measures should not replace the need for patching and updating the software to a secure version.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report covers CVE-2025-31635, a critical Path Traversal vulnerability discovered in LambertGroup&#8217;s CLEVER product.
