Summary

WAGO: Multiple Vulnerabilities in CODESYS Runtime 2.3 and WebVisualisation

Notes

Summary: Multiple vulnerabilities were reported in CODESYS 2.3 Runtime. The CODESYS 2.3 Runtime is an essential component in several WAGO PLCs. All vulnerable PLCs are listed in chapter 'Affected Products'. https://www.codesys.com/security/security-reports.html

Mitigation: 1. Use general security best practices to protect systems from local and network attacks. 2. Do not allow direct access to the device from untrusted networks. 3. Update to the latest firmware according to the table in chapter solutions. 4. Disable the CODESYS 2.3 WebVisualisation and CODESYS 2.3 port 2455. For further impact information and risk mitigation, please refer to the official CODESYS Advisory Website at https://www.codesys.com/security/security-reports.html

Impact: A successful attack stops all network communication. To restore the network connectivity the device needs to be restarted. The automation task is not affected.

Remediation: UPDATE A: fixed Firmware versions for 750-890/0xx-xxx, 750-891 and 750-893 We recommend all effected users with CODESYS 2.3 Runtime PLCs to update to the firmware version listed below.

CVE-2021-34584

Crafted web server requests can be utilised to read partial stack or heap memory or may trigger a denial-of- service condition due to a crash in the CODESYS V2 web server prior to V1.1.9.22.

9.1 (Critical)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H

CWE-126 - Buffer Over-read

Mitigation 1. Use general security best practices to protect systems from local and network attacks. 2. Do not allow direct access to the device from untrusted networks. 3. Update to the latest firmware according to the table in chapter solutions. 4. Disable the CODESYS 2.3 WebVisualisation and CODESYS 2.3 port 2455.

CVE-2021-34595

A crafted request with invalid offsets may cause an out-of-bounds read or write access in CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56, resulting in a denial-of-service condition or local memory overwrite.

8.1 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H

CWE-823 - Use of Out-of-range Pointer Offset

CVE-2021-34583

Crafted web server requests may cause a heap-based buffer overflow and could therefore trigger a denial-of- service condition due to a crash in the CODESYS V2 web server prior to V1.1.9.22.

7.5 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-122 - Heap-based Buffer Overflow

CVE-2021-34585

In the CODESYS V2 web server prior to V1.1.9.22 crafted web server requests can trigger a parser error. Since the parser result is not checked under all conditions, a pointer dereference with an invalid address can occur. This leads to a denial of service situation.

7.5 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-252 - Unchecked Return Value

CVE-2021-34586

In the CODESYS V2 web server prior to V1.1.9.22 crafted web server requests may cause a Null pointer dereference in the CODESYS web server and may result in a denial-of-service condition.

7.5 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-476 - NULL Pointer Dereference

CVE-2021-34596

A crafted request may cause a read access to an uninitialized pointer in CODESYS V2 Runtime Toolkit 32 Bit full and PLCWinNT prior to versions V2.4.7.56, resulting in a denial-of-service condition.

6.5 (Medium)


                        
                          CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

CWE-824 - Access of Uninitialized Pointer
