CVE-2022-32136

CWE-824
 

 
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.

 
 
CVE-2022-32137

CWE-122
 

 
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.

 
 
CVE-2022-32138

CWE-194
 

 
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.

 
 
CVE-2022-32139

CWE-125
 

 
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.

 
 
CVE-2022-32140

CWE-120
 

 
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 required.

 
 
CVE-2022-32141

CWE-126
 

 
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.

 
 
CVE-2022-32142

CWE-823
 

 
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 memory overwrite, which can lead to a change of local files. User interaction is not required.

 
 
CVE-2022-32143

CWE-552
 

 
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 or if remote attacker has previously successfully authenticated himself to the controller. A successful Attack may lead to a denial of service, change of local files, or drain of confidential Information. User interaction is not required

CWE-755
 

 
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.
