MicroLogix 1400 PLC Web Server Multiple Vulnerabilities
High Nessus Plugin ID 91384
SynopsisThe remote programmable logic controller (PLC) device is affected by multiple vulnerabilities.
DescriptionThe 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)
SolutionUpgrade to the latest firmware version. Alternatively, block all ports from external networks. See the vendor for further details.
