      <title>CVE-2012-6435 — Rockwell Automation ControlLogix PLC Improper Access Control</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2012-6435</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Rockwell Automation 1756-ENBT, 1756-EWEB, 1768-ENBT, 1768-EWEB communication modules, Rockwell Automation CompactLogix L32E and L35E controllers, Rockwell Automation 1788-ENBT FLEXLogix adapter, Rockwell Automation 1794-AENTR FLEX I/O EtherNet/IP adapter, Rockwell Automation ControlLogix, CompactLogix, GuardLogix, and SoftLogix, Rockwell Automation CompactLogix and SoftLogix controllers, Rockwell Automation ControlLogix and GuardLogix controllers, Rockwell Automation MicroLogix&lt;/p&gt;
&lt;p&gt;When an affected product receives a valid CIP message from an unauthorized or unintended source to Port 2222/TCP, Port 2222/UDP, Port 44818/TCP, or Port 44818/UDP that instructs the CPU to stop logic execution and enter a fault state, a DoS can occur. This situation could cause loss of availability and a disruption of communication with other connected devices.&lt;/p&gt;
&lt;p&gt;Rockwell Automation EtherNet/IP products; 1756-ENBT, 1756-EWEB, 1768-ENBT, and 1768-EWEB communication modules; CompactLogix L32E and L35E controllers; 1788-ENBT FLEXLogix adapter; 1794-AENTR FLEX I/O EtherNet/IP adapter; ControlLogix 18 and earlier; CompactLogix 18 and earlier; GuardLogix 18 and earlier; SoftLogix 18 and earlier; CompactLogix controllers 19 and earlier; SoftLogix controllers 19 and earlier; ControlLogix controllers 20 and earlier; GuardLogix controllers 20 and earlier; and MicroLogix 1100 and 1400&lt;/p&gt;</description>
