CVE-2008-6590: Path Traversal
Multiple directory traversal vulnerabilities in LightNEasy "no database" (aka flat) version 1.2.2, and possibly SQLite version 1.2.2, allow remote attackers to read arbitrary files via a .. (dot dot) in the page parameter to (1) index.php and (2) LightNEasy.php.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Modify input validation in index.php and LightNEasy.php to reject or canonicalize any 'page' parameter values that contain directory-traversal sequences (e.g., '..' or percent-encoded forms such as %2e%2e). Ensure the application returns an error for such requests or normalizes the path to a safe base directory.
LightNEasy (flat/no-database) 1.2.2 page parameter validation = reject or canonicalize any '..' sequences and their percent-encoded equivalents - Compensating control
Deploy a web application firewall or reverse-proxy rule to block requests to index.php and LightNEasy.php that include '..' or URL-encoded equivalents (e.g., %2e%2e) in the 'page' parameter. If a WAF is not available, restrict network access to LightNEasy 1.2.2 and SQLite 1.2.2 endpoints to trusted IP addresses via firewall/ACLs to prevent remote exploitation.
