Synopsis
The remote programmable logic controller (PLC) device is affected by multiple vulnerabilities.Description
The firmware installed on the remote Allen-Bradley MicroLogix 1400 PLC device is a version prior to 15.003. It is, therefore, affected by multiple vulnerabilities :- A flaw exists due to improper sanitization of user-supplied input before using it in SQL queries. An authenticated, remote attacker can exploit this to inject SQL queries against the back-end database, resulting in the manipulation or disclosure of arbitrary data. (CVE-2015-6486)
- A cross-site scripting (XSS) vulnerability exists due to improper validation of input before returning it to users. An unauthenticated, remote attacker can exploit this, via a crafted request, to execute arbitrary script code in the user's browser session. (CVE-2015-6488)
- A flaw exists due to improper sanitization of user-supplied input before returning it to users. An authenticated, remote attacker can exploit this to insert into a FRAME element the content of an include file from a remote host, resulting in the execution of arbitrary commands or code with the same privileges as the web server. (CVE-2015-6491)
- A memory corruption issue exists that allows an unauthenticated, remote attacker, via a crafted HTTP request, to crash the device, resulting in a denial of service condition. (CVE-2015-6492)
Solution
Upgrade to the latest firmware version. Alternatively, block all ports from external networks. See the vendor for further details.See Also
