Directory traversal vulnerability in page.recordings.php in the System Recordings component in the configuration interface in FreePBX 2.8.0 and earlier allows remote authenticated administrators to create arbitrary files via a .. (dot dot) in the usersnum parameter to admin/config.php, as demonstrated by creating a .php file under the web root.

The IAX2 protocol implementation in Asterisk Open Source 1.2.x before 1.2.35, 1.4.x before 1.4.26.2, 1.6.0.x before 1.6.0.15, and 1.6.1.x before 1.6.1.6; Business Edition B.x.x before B.2.5.10, C.2.x before C.2.4.3, and C.3.x before C.3.1.1; and s800i 1.3.x before 1.3.0.3 allows remote attackers to cause a denial of service (call-number exhaustion) by initiating many IAX2 message exchanges, a related issue to CVE-2008-3263.

Multiple cross-site scripting (XSS) vulnerabilities in FreePBX 2.5.1, and other 2.4.x, 2.5.x, and pre-release 2.6.x versions, allow remote attackers to inject arbitrary web script or HTML via the (1) display parameter to reports.php, the (2) order and (3) extdisplay parameters to config.php, and the (4) sort parameter to recordings/index.php. NOTE: some of these details are obtained from third party information.

FreePBX 2.5.1, and other 2.4.x, 2.5.x, and pre-release 2.6.x versions, generates different error messages for a failed login attempt depending on whether the user account exists, which allows remote attackers to enumerate valid usernames.

Multiple cross-site request forgery (CSRF) vulnerabilities in FreePBX 2.5.1, and other 2.4.x, 2.5.x, and pre-release 2.6.x versions, allow remote attackers to hijack the authentication of admins for requests that create a new admin account or have unspecified other impact.

Multiple race conditions in WANPIPE before 3.3.6 have unknown impact and attack vectors related to "bri restart logic."
