CODESYS V2 runtime system SP before 2.4.7.55 has a Stack-based Buffer Overflow.

An exploitable stack buffer overflow vulnerability exists in the command line utility getcouplerdetails of WAGO PFC200 Firmware versions 03.01.07(13) and 03.00.39(12), and WAGO PFC100 Firmware version 03.00.39(12). A specially crafted set of packets sent to the iocheckd service "I/O-Check" can cause a stack buffer overflow in the sub-process getcouplerdetails, resulting in code execution. An attacker can send unauthenticated packets to trigger this vulnerability.

An exploitable stack buffer overflow vulnerability exists in the iocheckd service ''I/O-Check'' functionality of WAGO PFC200 Firmware version 03.01.07(13), WAGO PFC200 Firmware version 03.00.39(12) and WAGO PFC100 Firmware version 03.00.39(12).

CODESYS V2 Web-Server before 1.1.9.20 has a Stack-based Buffer Overflow.

CODESYS V2 Web-Server before 1.1.9.20 has an Out-of-bounds Write.

In multiple products of WAGO a vulnerability allows an unauthenticated, remote attacker to create new users and change the device configuration which can result in unintended behaviour, Denial of Service and full system compromise.

This vulnerability allows an attacker who has access to the WBM to read and write settings-parameters of the device by sending specifically constructed requests without authentication on multiple WAGO PLCs in firmware versions up to FW07.

CODESYS V2 Web-Server before 1.1.9.20 has an Improperly Implemented Security Check.

A vulnerability in the web-based management allows an unauthenticated remote attacker to inject arbitrary system commands and gain full system control. Those commands are executed with root privileges. The vulnerability is located in the user request handling of the web-based management.

The configuration backend allows an unauthenticated user to write arbitrary data with root privileges to the storage, which could lead to unauthenticated remote code execution and full system compromise.

The configuration backend of the web-based management can be used by unauthenticated users, although only authenticated users should be able to use the API. The vulnerability allows an unauthenticated attacker to read and set several device parameters that can lead to full compromise of the device.

The Linux Console on the WAGO I/O System 758 model 758-870, 758-874, 758-875, and 758-876 Industrial PC (IPC) devices has a default password of wago for the (1) root and (2) admin accounts, (3) a default password of user for the user account, and (4) a default password of guest for the guest account, which makes it easier for remote attackers to obtain login access via a TELNET session, a different vulnerability than CVE-2012-3013.

WAGO I/O System 758 model 758-870, 758-874, 758-875, and 758-876 Industrial PC (IPC) devices have default passwords for unspecified Web Based Management accounts, which makes it easier for remote attackers to obtain administrative access via a TCP session.

The reported vulnerability allows an attacker who has network access to the device to execute code with specially crafted packets in WAGO Series PFC 100 (750-81xx/xxx-xxx), Series PFC 200 (750-82xx/xxx-xxx), Series Wago Touch Panel 600 Standard Line (762-4xxx), Series Wago Touch Panel 600 Advanced Line (762-5xxx), Series Wago Touch Panel 600 Marine Line (762-6xxx) with firmware versions <=FW10.

eap.c in pppd in ppp 2.4.2 through 2.4.8 has an rhostname buffer overflow in the eap_request and eap_response functions.

WAGO 852-303 before FW06, 852-1305 before FW06, and 852-1505 before FW03 devices contain hardcoded users and passwords that can be used to login via SSH and TELNET.

WAGO 852-303 before FW06, 852-1305 before FW06, and 852-1505 before FW03 devices contain hardcoded private keys for the SSH daemon. The fingerprint of the SSH host key from the corresponding SSH daemon matches the embedded private key.

WAGO IO 750-849 01.01.27 and WAGO IO 750-881 01.02.05 do not contain privilege separation.

In multiple managed switches by WAGO in different versions without authorization and with specially crafted packets it is possible to create users.

Crafted web server requests may cause a heap-based buffer overflow and could therefore trigger a denial-of- service condition due to a crash in the CODESYS V2 web server prior to V1.1.9.22.

CODESYS V2 runtime system SP before 2.4.7.55 has a Heap-based Buffer Overflow.

An exploitable stack buffer overflow vulnerability vulnerability exists in the iocheckd service ‘I/O-Check’ functionality of WAGO PFC 200 Firmware version 03.02.02(14).

An exploitable stack buffer overflow vulnerability vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC 200. An attacker can send a specially crafted packet to trigger the parsing of this cache file. At 0x1ea28 the extracted state value from the xml file is used as an argument to /etc/config-tools/config_interfaces interface=X1 state=<contents of state node> using sprintf().

Later, at 0x1ea08 strcpy() is used to copy the contents of the stack buffer that was overflowed sp+0x40 into sp+0x440. The buffer sp+0x440 is immediately adjacent to sp+0x40 on the stack. Therefore, there is no NULL termination on the buffer sp+0x40 since it overflowed into sp+0x440. The strcpy() will result in invalid memory access. An state value of length 0x3c9 will cause the service to crash.
