High 7.5
Uncontrolled Memory Allocation in CODESYS Gateway Client
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 cons…

High 8.1
Improper Synchronization in Monitoring in CODESYS Control Runtime
Affected products do not properly synchronize access to their monitoring functionality. When multiple clients send concurrent requests, this may lead to incorrect reads or writes, or to corruption of internal memory structures. An authenticated remote attacke…

High 8.3
CODESYS Control PKI Exposure Enables Remote Certificate Access
A low-privileged attacker can remotely access the PKI folder of the CODESYS Control runtime system and thus read and write certificates and its keys. This allows sensitive data to be extracted or to accept certificates as trusted. Although all services remain…

CODESYS: Exposure of Resource to Wrong Sphere in CODESYS V3
In multiple products of CODESYS v3 in multiple versions a remote low privileged user could utilize this vulnerability to read and modify system files and OS resources or DoS the device.

High 8.8
CODESYS runtime system prone to directory acces
In multiple CODESYS products, file download and upload function allows access to internal files in the working directory e.g. firmware files of the PLC. All requests are processed on the controller only if no level 1 password is configured on the controller o…

High 8.1
CODESYS runtime system prone to denial of service due to use of out of range pointer
Multiple CODESYS Products are prone to a out-of bounds read or write access. A low privileged remote attacker may craft a request with invalid offset, which can cause an out-of-bounds read or write access, resulting in denial-of-service condition or local mem…

CODESYS runtime system prone to denial of service due to buffer over read
Multiple CODESYS Products are prone to a buffer over read. A low privileged remote attacker may craft a request with an invalid offset, which can cause an internal buffer over-read, resulting in a denial-of-service condition. User interaction is not required.

Medium 6.5
CODESYS runtime system prone to denial of service due to buffer copy
Multiple CODESYS products are affected to a buffer overflow.A low privileged remote attacker may craft a request, which can cause a buffer copy without checking the size of the service, resulting in a denial-of-service condition. User Interaction is not requi…

CODESYS runtime system prone to denial of service due to out of bounds read
In multiple CODESYS products, a low privileged remote attacker may craft a request, which cause an out-of-bounds read, resulting in a denial-of-service condition. User Interaction is not required.

High 8.8
CODESYS runtime system prone to denial of service due to Unexpected Sign Extension
In multiple CODESYS products, a remote attacker may craft a request which may cause an unexpected sign extension, resulting in a denial-of-service condition or memory overwrite.
-
High 8.8
CODESYS Runtime System prone to heap based buffer overflow
In multiple CODESYS products, a low privileged remote attacker may craft a request, which may cause a heap-based buffer overflow, resulting in a denial-of-service condition or memory overwrite. User interaction is not required.
-
Medium 6.5
Codesys runtime systems: Access of uninitialised pointer lead to denial of service.
In multiple CODESYS products, a low privileged remote attacker may craft a request that cause a read access to an uninitialized pointer, resulting in a denial-of-service. User interaction is not required.

High 8.1
CODESYS runtime system prone to file deletion due to improper error handling
Multiple products of CODESYS implement a improper error handling. A low privilege remote attacker may craft a request, which is not properly processed by the error handling. In consequence, the file referenced by the request could be deleted. User interaction…
