The CODESYS Gateway Client allocates memory based on a size field in a gateway response without enforcing an appropriate upper limit. An unauthenticated remote attacker controlling a malicious gateway can exploit this behavior to trigger excessive memory consumption, resulting in...
A local attacker with low privileges can read and modify any users files and cause a DoS in the working directory of the affected products due to exposure of resource to wrong sphere.
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.
In the CODESYS Development System multiple components in multiple versions transmit the passwords for the communication between clients and servers unprotected.
The CODESYS Gateway Server V2 does not verifiy that the size of a request is within expected limits. An unauthenticated attacker may allocate an arbitrary amount of memory, which may lead to a crash of the Gateway due to an out-of-memory condition.
In CODESYS Gateway Server V2 an insufficient check for the activity of TCP client connections allows an unauthenticated attacker to consume all available TCP connections and prevent legitimate users or clients from establishing a new connection to the CODESYS Gateway Server V2. E...
In CODESYS Gateway Server V2 for versions prior to V2.3.9.38 only a part of the the specified password is been compared to the real CODESYS Gateway password. An attacker may perform authentication by specifying a small password that matches the corresponding part of the longer re...
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.
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...
An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.
In CODESYS Gateway V3 before 3.5.17.10, there is a NULL Pointer Dereference. Crafted communication requests may cause a Null pointer dereference in the affected CODESYS products and may result in a denial-of-service condition.
CODESYS Control Runtime system before 3.5.17.0 has improper input validation. Attackers can send crafted communication packets to change the router's addressing scheme and may re-route, add, remove or change low level communication packages.
CODESYS Gateway 3 before 3.5.16.70 has a NULL pointer dereference that may result in a denial of service (DoS).
CODESYS Control V3, Gateway V3, and HMI V3 before 3.5.15.30 allow uncontrolled memory allocation which can result in a remote denial of service condition.
An issue was discovered in 3S-Smart CODESYS before 3.5.15.0 . Crafted network packets cause the Control Runtime to crash.
An issue was discovered in 3S-Smart CODESYS V3 products. A crafted communication request may cause uncontrolled memory allocations in the affected CODESYS products and may result in a denial-of-service condition. All variants of the following CODESYS V3 products in all versions p...
An issue was discovered in 3S-Smart CODESYS V3 products. The CODESYS Gateway does not correctly verify the ownership of a communication channel. All variants of the following CODESYS V3 products in all versions prior to v3.5.14.20 that contain the CmpGateway component are affecte...
Improper Communication Address Filtering exists in CODESYS V3 products versions prior V3.5.14.0.
Use of Insufficiently Random Values exists in CODESYS V3 products versions prior V3.5.14.0.
