Recent Codesys Security Vulnerabilities
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.
CVE-2021-34586
7.5 - High
- October 26, 2021
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.
NULL Pointer Dereference
In the CODESYS V2 web server prior to V1.1.9.22 crafted web server requests can trigger a parser error
CVE-2021-34585
7.5 - High
- October 26, 2021
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.
Unchecked Return Value
Crafted web server requests
CVE-2021-34584
9.1 - Critical
- October 26, 2021
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.
Buffer Over-read
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.
CVE-2021-34583
7.5 - High
- October 26, 2021
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.
