CVE-2015-6490 is a stack-based buffer overflow vulnerability affecting Allen-Bradley MicroLogix 1100 devices before B FRN 15.000 and MicroLogix 1400 devices through B FRN 15.003. The flaw allows a remote attacker to trigger memory corruption via unspecified network vectors and potentially execute arbitrary code on the targeted programmable logic controller. The vulnerability affects industrial control devices used in operational technology environments, making successful exploitation particularly significant because it can compromise controller integrity and plant operations.
