DESCRIPTION:
Two vulnerabilities have been reported in FreePBX, which can be
exploited by malicious users to compromise a vulnerable system and by
malicious people to conduct cross-site scripting attacks.

1) Input passed to the "login" parameter in recordings/index.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 "callmenum" parameter in
recordings/misc/callme_page.php (when "action" is set to "c") is not
properly verified before being used. This can be exploited to inject
and execute arbitrary shell commands.

The vulnerabilities are reported in version 2.10.0. Other versions
may also be affected.

SOLUTION:
Fixed in the SVN repository.
