TITLE

Rockwell Automation MicroLogix 1100 PLC Stack Buffer Overflow Vulnerability

Trust: 0.8

sources: IVD: 63099e7a-2351-11e6-abef-000c29c66e3d // CNVD: CNVD-2016-00717

DESCRIPTION

Stack-based buffer overflow on Rockwell Automation Allen-Bradley MicroLogix 1100 devices A through 15.000 and B before 15.002 allows remote attackers to execute arbitrary code via a crafted web request. Rockwell Automation Allen-Bradley MicroLogix 11001763-L16AWA is a programmable logic controller (PLC) product from Rockwell Corporation of the United States. Multiple MicroLogix 1100 PLC products are prone to a stack-based buffer-overflow vulnerability because it fails to perform adequate boundary-checks on user supplied data. Failed exploit attempts will likely cause denial-of-service conditions. Rockwell Automation Allen-Bradley MicroLogix 1100 1763-L16AWA, etc. The following models and revisions are affected: Allen-Bradley MicroLogix 1100 1763-L16AWA (Series B), 1763-L16BBB (Series B), 1763-L16BWA (Series B), 1763-L16DWD (Series B), 1763-L16AWA (Series A ), 1763-L16BBB (Series A), 1763-L16BWA (Series A), 1763-L16DWD (Series A) 15.000 and earlier
