Unlock Password Plc Siemens S7 300 Rarl
the simatic s7-300 series is the most advanced programmable logic controller from siemens plm software. it is the upgrade version of the s7-200 series and supports a user friendly software framework. it is a programmable logic controller, which can be used for industrial automation. thanks to its user friendly interface, the software is highly compatible with the industrial field. it was launched in 1996 and they are designed and manufactured by siemens.
now, we will explain the reason for setting a new password to the plc. firstly, it is required for security reasons. the plc password is set for each device individually. it is set on the configuration software and on the plc itself. before a function or a command is executed, the load process first checks the block number 0000 and if there is a password set, it is not executed.
the plc password can be updated in case the old password is not available. for example, in the case the plc is not password protected, the engineer may update the password with a new one to change its security. in this case, the old password is automatically removed. the new password is automatically saved in the sdb block.
when siemens industrial control systems were initially developed in the early 2000s, none of them used ssl, which was designed to guarantee that the data that is transmitted over the internet is secure. this made the systems vulnerable to remote attacks, where hackers had complete access to the plant and everything in it.
last week, security researcher dillon beresford published a set of vulnerabilities in siemens industrial control systems. these vulnerabilities are so serious that they could be used to reprogram the devices and cause them to crash, which would affect the devices’ ability to control anything in the plant. these vulnerabilities include a hard-coded password that allows hackers to connect to the devices and do anything they want.
our tool uses a simple c program called “exploit_code_download.c” to download, manipulate, and push the malicious code to siemens plcs. in the very first step, it has to upload itself to its own machine where the plc runs to prove that it is not a virus. when that step succeeded, it connects to the plc and downloads its control program. at this stage, the main focus is to program the control block “ob0” with a simple set of instructions and then unlock the plc with this code. in order to achieve this mission, we set all the input parameters to zero such as, address pins, output pins, currents, etc. and initiate the programming and downloading process. after the programming process, an instruction that locks the plc is executed. after this step, the injected code is unlocked and the plc is ready for further processing
our tool doesn’t check if the plc is the siemens s7 300 or s7 300 r, so it downloads and injects code for both types of devices. this is because it is only targeting mobile devices that run siemens plcs, so siemens 300r is available to attack
we sent the program to siemens and asked them to look into our findings. after we received their findings, we were asked by the manufacturer’s security team to let them know. however, we were asked to sign nda, which we refused.
we do not know how the main siemens plc security is implemented. so we were able to break that instead of breaking siemens security. moreover, we plan to release our tool to the public after we’ve fixed all our findings. the tool was tested under linux and windows 10 os, and it successfully uploaded and then injected its own program on siemens s7 300 rarl. the tool is written in c language and we have shown the program flow in fig. 7. the basic functionality of the tool is as follows:
