A memory leak vulnerability in sim-organizer.c of AlienVault Ossim v5 causes a denial of service (DOS) via a system crash triggered by the occurrence of a large number of alarm events.

AlienVault USM and OSSIM before 5.3.7 and NfSen before 1.3.8 have an error in privilege dropping and unnecessarily execute the NfSen Perl code as root, aka AlienVault ID ENG-104945, a different vulnerability than CVE-2017-6970 and CVE-2017-6971.

AlienVault USM and OSSIM before 5.3.7 and NfSen before 1.3.8 allow remote authenticated users to execute arbitrary commands in a privileged context, or launch a reverse shell, via vectors involving the PHP session ID and the NfSen PHP code, aka AlienVault ID ENG-104862.

AlienVault USM and OSSIM before 5.3.7 and NfSen before 1.3.8 allow local users to execute arbitrary commands in a privileged context via an NfSen socket, aka AlienVault ID ENG-104863.

The logcheck function in session.inc in AlienVault OSSIM before 5.3.1, when an action has been created, and USM before 5.3.1 allows remote attackers to bypass authentication and consequently obtain sensitive information, modify the application, or execute arbitrary code as root via an "AV Report Scheduler" HTTP User-Agent header.

Open Source Security Information Management (OSSIM) before 2.1.2 allows remote attackers to bypass authentication, and read graphs or infrastructure information, via a direct request to (1) graphs/alarms_events.php or (2) host/draw_tree.php.

Multiple SQL injection vulnerabilities in Open Source Security Information Management (OSSIM) before 2.1.2 allow remote authenticated users to execute arbitrary SQL commands via the id_document parameter to (1) repository_document.php, (2) repository_links.php, and (3) repository_editdocument.php in repository/; the (4) group parameter to policy/getpolicy.php; the name parameter to (5) host/newhostgroupform.php and (6) net/modifynetform.php; and unspecified other vectors related to the policy menu.

Cross-site scripting (XSS) vulnerability in Open Source Security Information Management (OSSIM) before 2.1.2 allows remote attackers to inject arbitrary web script or HTML via the option parameter to the default URI (aka the main menu).
