| <dt>Summary:</dt> |
| <dd><p>Some versions of mod_pagespeed and ngx_pagespeed are vulnerable to |
| cross-site scripting (XSS), which can permit a hostile 3rd party to |
| inject javascript running in the context of the site.</p></dd> |
| <dt>Solution:</dt> |
| <dd><p>For mod_pagespeed, update to one of versions 1.0.22.8-stable, |
| 1.2.24.2-stable, 1.3.25.5-stable, 1.4.26.5-stable, 1.5.27.4-beta, or |
| 1.6.29.7 or newer.</p> |
| |
| <p>For ngx_pagespeed, update to 1.6.29.7 or newer.</p> |
| </dd> |
| <dt>Workaround:</dt> |
| <dd> |
| <p>No workaround is available for mod_pagespeed.</p> |
| |
| <p>For ngx_pagespeed, you can completely prohibit access to |
| <code>/ngx_pagespeed_statistics</code>, |
| <code>/ngx_pagespeed_global_statistics</code> and |
| <code>/ngx_pagespeed_message</code> (an IP whitelist is insufficient), via |
| options similar to: |
| <pre> |
| location /ngx_pagespeed_global_statistics { deny all; } |
| location /ngx_pagespeed_statistics { deny all; } |
| location /ngx_pagespeed_message { deny all; } |
| </pre> |
