Mon Album 0.8.7
http://www.3dsrc.com/monalbum/

There are 2 sql injection flaws in MonAlbum 0.8.7. First in index.php (line 99)
if (isset($_GET["pc"])) $pc = $_GET["pc"];

... (no sanity checks)

if (isset($pc) && $grech_inactive) $result = execute_requete("select id_rub, 
nom, commentaire from monalbum_rubrique where ( nom like \"%$pc%\" or 
commentaire like \"%$pc%\" ) and (id_rub_mere <> 0 and id_rub <> 0) limit " . 
$deb . ", ". ($ghor*$gvert));



The second flaw is located in the comments system in image_agrandir.php (line 
228)
$pnom = $_POST['pnom'];
$pcourriel = $_POST['pcourriel'];
$pcommentaire = $_POST['pcommentaire'];

... (no sanity checks)

execute_requete("insert into monalbum_commentaire (id_image, nom, courriel, 
commentaire, date_com) values ($id_image, \"$pnom\",\"$pcourriel\", 
\"".addslashes($pcommentaire)."\", \"".date("Y-m-d")."\" )");
