TITLE:
ACollab Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA35173
VERIFY ADVISORY:
http://secunia.com/advisories/35173/
DESCRIPTION:
Russ McRee has discovered some vulnerabilities in ACollab, which can
be exploited by malicious users to conduct script insertion attacks
and by malicious people to conduct cross-site scripting and
cross-site request forgery attacks.
1) Input passed to the "f" parameter in sign_in.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 via e.g. the "address" parameter in profile.php or
the "description" parameter in events/add_event.php is not properly
sanitised before being used. This can be exploited to insert
arbitrary HTML and script code, which will be executed in a user's
browser session when the malicious data is viewed.
3) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. add members or groups when a
logged-in administrator visits a specially crafted web page.
The vulnerabilities are confirmed in version 1.2. Other versions may
also be affected.
SOLUTION:
The vendor will discontinue the support for ACollab.
Use another product.
