DESCRIPTION:
Gjoko Krstic has discovered multiple vulnerabilities in AChecker,
which can be exploited by malicious people to conduct cross-site
scripting and SQL injection attacks.

1) Input passed to the "id" parameter in
themes/default/language/language_add_edit.tmpl.php and in
themes/default/user/user_group_create_edit.tmpl.php is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

2) Input passed to the "p" parameter in
documentation/frame_header.php is not properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

3) Input passed to the "id" parameter in user/user_create_edit.php
and the "myown_patch_id" parameter in updater/patch_edit.php is not
properly sanitised before being returned to the user within an SQL
error message in the "execute()" function
(include/classes/DAO/DAO.class.php). This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

4) Input passed to the "id" parameter in user/user_create_edit.php
and the "myown_patch_id" parameter in updater/patch_edit.php is not
properly sanitised before being used in a SQL query in the
"execute()" function (include/classes/DAO/DAO.class.php). This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities are confirmed in version 1.2. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
