An attacker may cause a denial of service by crafting an Accept-Language header which ParseAcceptLanguage will take significant time to parse.

A vulnerability has been identified in Teamcenter Active Workspace V5.2 (All versions < V5.2.9), Teamcenter Active Workspace V6.0 (All versions < V6.0.3). A reflected cross-site scripting (XSS) vulnerability exists in the web interface of the affected application that could allow an attacker to execute malicious code by tricking users into accessing a malicious link.

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

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.

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.
