CVE-2008-4360: Debian Linux

High severity, CVSS 7.5. EPSS: 4.3% chance of exploitation in the next 30 days.

mod_userdir in lighttpd before 1.4.20, when a case-insensitive operating system or filesystem is used, performs case-sensitive comparisons on filename components in configuration options, which might allow remote attackers to bypass intended access restrictions, as demonstrated by a request for a .PHP file when there is a configuration rule for .php files.

Affected products

  • Debian Debian Linux: version 4.0 only
  • Lighttpd Lighttpd: before 1.4.20 (fixed in 1.4.20)
