CVSS v3.1 |
| 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. |
| The SysDrv3S driver in the CODESYS Control runtime system on Microsoft Windows allows any system user to read and write within restricted memory space. |
| 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, this results in a crash. |
| An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash. |
| Codesys Profinet in version V4.2.0.0 is prone to null pointer dereference that allows a denial of service (DoS) attack of an unauthenticated user via SNMP. |
| All CODESYS Visualization versions before V4.2.0.0 generate a login dialog vulnerable to information exposure allowing a remote, unauthenticated attacker to enumerate valid users. |
| 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 is not required. |
| The CODESYS OPC DA Server prior V3.5.18.20 stores PLC passwords as plain text in its configuration file so that it is visible to all authorized Microsoft Windows users of the system. |
| In CODESYS EtherNetIP before 4.1.0.0, specific EtherNet/IP requests may cause a null pointer dereference in the downloaded vulnerable EtherNet/IP stack that is executed by the CODESYS Control runtime system. |
| 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. |
| In CODESYS V3 web server before 3.5.17.10, files or directories are accessible to External Parties. |
| Affected versions of CODESYS Git in Versions prior to V1.1.0.0 lack certificate validation in HTTPS handshakes. CODESYS Git does not implement certificate validation by default, so it does not verify that the server provides a valid and trusted HTTPS certificate. Since the certificate of the server to which the connection is made is not properly verified, the server connection is vulnerable to a man-in-the-middle attack. |
| All versions of the CODESYS V3 Runtime Toolkit for VxWorks from version V3.5.8.0 and before version V3.5.17.10 have Improper Handling of Exceptional Conditions. |
| CODESYS Control Runtime system before 3.5.17.10 has a Heap-based Buffer Overflow. |
| 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). |
| The Package Manager of CODESYS Development System 3 before 3.5.17.0 does not check the validity of packages before installation and may be used to install CODESYS packages with malicious content. |
