Vulnerabilidades

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.

A CORS Misconfiguration in the web-based management allows a malicious third party webserver to misuse all basic information pages on the webserver. In combination with CVE-2022-45138 this could lead to disclosure of device information like CPU diagnostics. As there is just a limited amount of information readable the…

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 configuration backend of the web-based management is vulnerable to reflected XSS (Cross-Site Scripting) attacks that targets the users browser. This leads to a limited impact of confidentiality and integrity but no impact of availability.

In WAGO Unmanaged Switch (852-111/000-001) in firmware version 01 an undocumented configuration interface without authorization allows an remote attacker to read system information and configure a limited set of parameters.

The vulnerability allows a remote unauthenticated attacker to download a backup file, if one exists. That backup file might contain sensitive information like credentials and cryptographic material. A valid user has to create a backup after the last reboot for this attack to be successfull.

In CODESYS V3 products in all versions prior V3.5.16.0 containing the CmpUserMgr, the CODESYS Control runtime system stores the online communication passwords using a weak hashing algorithm. This can be used by a local attacker with low privileges to gain full control of the device.

In WAGO I/O-Check Service in multiple products an attacker can send a specially crafted packet containing OS commands to crash the diagnostic tool and write memory.

In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to provoke a denial of service.

In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to provoke a denial of service and an limited out-of-bounds read.

In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to crash the iocheck process and write memory resulting in loss of integrity and DoS.

WAGO Series PFC100/PFC200, Series Touch Panel 600, Compact Controller CC100 and Edge Controller in multiple versions are prone to a loss of MAC-Address-Filtering after reboot. This may allow an remote attacker to circumvent the reach the network that should be protected by the MAC address filter.

In CmpChannelServer of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new communication channel connections. Existing connections are not affected.

In CmpBlkDrvTcp of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new TCP connections. Existing connections are not affected.

A remote, unauthenticated attacker can send a specific crafted HTTP or HTTPS requests causing a buffer over-read resulting in a crash of the webserver of the CODESYS Control runtime system.

A bug in CmpUserMgr component can lead to only partially applied security policies. This can result in enabled, anonymous access to components part of the applied security policy.

An unauthenticated, remote attacker can disrupt existing communication channels between CODESYS products by guessing a valid channel ID and injecting packets. This results in the communication channel to be closed.

A remote, authenticated attacker could utilize the control program of the CODESYS Control runtime system to use the vulnerability in order to read and modify the configuration file(s) of the affected products.

An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally nor control the values to be written. If invalid memory is accessed,…

An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.

Various configuration pages of the device are vulnerable to reflected XSS (Cross-Site Scripting) attacks. An authorized attacker with user privileges may use this to gain access to confidential information on a PC that connects to the WBM after it has been compromised.

A crafted request may cause a read access to an uninitialized pointer in CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56, resulting in a denial-of-service condition.

A crafted request with invalid offsets may cause an out-of-bounds read or write access in CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56, resulting in a denial-of-service condition or local memory overwrite.

In CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56 unauthenticated crafted invalid requests may result in several denial-of-service conditions. Running PLC programs may be stopped, memory may be leaked, or further communication clients may be blocked from accessing the PLC.

In the CODESYS V2 web server prior to V1.1.9.22 crafted web server requests may cause a Null pointer dereference in the CODESYS web server and may result in a denial-of-service condition.
