Siemens SIMATIC S7-1200 CPU open Redirection Vulnerability (CVE-2015-1048)
Release date:Updated on:
Affected Systems:Siemens SIMATIC S7-1200 CPU Description:Bugtraq id: 72282CVE (CAN) ID: CVE-2015-1048
The SIMATIC S7-1200 is a programmable controller that enables simple but highly precise automation tasks.
Siemens SIMATIC S7-1200 CPU device (earlier than firmware 4.1) integrated Web server (port 80/tcp and port 443/tcp) has an open redirection vulnerability, remote attackers can exploit this

(such as SSH or Putty) and SpamAssassin 'ssa-learn program. The email server must also set the IMAP protocol to train SpamAssassin.
To train SpamAssassin, follow these steps:
1. Separate the spam from the normal email and put it in a separate email address.
2. Open the ssh application and connect to jupiter.gac.edu.
3. Run the following two commands:
Sa-learn -- ham -- progress -- mbox Mail/nameOfYourHamMailbox

At any time, functions, Eval code blocks, and Global Code may run simultaneously by llint, baseline JIT, and dfg. An extreme example is a recursive function. Because there are multiple stack frames, one may run in llint, the other may run in baseline JIT
perform type check when taking O. X and O. Y. Then we know that their values are doubles, that is, only the double multiplication and addition are triggered. Most dfg type checks usually occur when the heap data is loaded.

The database creation operation must be performed on the server, because the database creation operation through the client is only performed on the client machine. This database can only be used on a single machine. Note that VSS shares controlled version files on the server through WINDOWS network sharing. Therefore, the databases o

Before Raspberry Pi 2, I used an RTD1186-based HD player. How can I compare Raspberry Pi 2 using OpenELEC with a dedicated HD player?
Advantages:
Supports hdmi cec and can be directly operated using the TV remote control.
