  • Detect UTF-7 encoded XSS payloads in URLs triggering Apache 403 Forbidden error pages; look for UTF-7 sequences such as +ADw- (+ADw- = '<') and +AD4- (+AD4- = '>') in request URIs
  • Monitor HTTP requests containing URL-encoded or UTF-7 encoded script tags (e.g., +ADw-script+AD4- patterns) in the request path directed at Apache servers version 2.2.6 and earlier
  • The attack vector is a crafted URL path containing UTF-7 encoded HTML/script content; the payload is reflected in the 403 error page body without charset enforcement
  • ·This vulnerability only affects Apache configurations where the 'AddDefaultCharset' directive has been removed; default Red Hat configurations are not affected
  • ·The root cause is a browser-side weakness (failure to derive response charset per RFC 2616), not solely an Apache flaw; Internet Explorer is specifically identified as the vulnerable client
  • ·All versions of Internet Explorer are reported affected; other browsers may also be affected under certain configurations but this has not been confirmed
