CVSS v3.1 |
| CODESYS V2 runtime system SP before 2.4.7.55 has Improper Neutralization of Special Elements used in an OS Command. |
| CODESYS V2 runtime system SP before 2.4.7.55 has a Stack-based Buffer Overflow. |
| CODESYS V2 Web-Server before 1.1.9.20 has a Stack-based Buffer Overflow. |
| CODESYS V2 Web-Server before 1.1.9.20 has Improper Access Control. |
| CODESYS V2 Web-Server before 1.1.9.20 has a a Buffer Copy without Checking the Size of the Input. |
| CODESYS V2 Web-Server before 1.1.9.20 has an Improperly Implemented Security Check. |
| CODESYS V2 Web-Server before 1.1.9.20 has an Out-of-bounds Write. |
| CODESYS V2 Web-Server before 1.1.9.20 has an Out-of-bounds Read. |
| CODESYS V2 runtime system before 2.4.7.55 has Improper Input Validation. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| CODESYS V2 runtime system SP before 2.4.7.55 has a Heap-based Buffer Overflow. |
| CODESYS Runtime Toolkit-based products may expose sensitive files to local low-privileged operating system users due to default file permissions. |
| A low-privileged attacker can remotely access the PKI folder of the CODESYS Control runtime system and thus read and write certificates and its keys. This allows sensitive data to be extracted or to accept certificates as trusted. Although all services remain available, only unencrypted communication is possible if the certificates are deleted. |
| An unauthenticated remote attacker may trigger a NULL pointer dereference in the affected CODESYS Control runtime systems by sending specially crafted communication requests, potentially leading to a denial-of-service (DoS) condition. |
