CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 1CVE-2021-34586 – CODESYS V2 web server: crafted requests could trigger a null pointer dereference (DoS)
https://notcve.org/view.php?id=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. En el servidor web de CODESYS V2 versiones anteriores a 1.1.9.22, unas peticiones del servidor web diseñadas pueden causar una desreferencia de puntero Null en el servidor web de CODESYS y puede resultar en una condición de denegación de servicio • https://customers.codesys.com/index.php?eID=dumpFile&t=f&f=16876&token=a3f1d937f95e7034879f4f2ea8e5a99b168256a7&download= https://www.tenable.com/security/research/tra-2021-47 • CWE-476: NULL Pointer Dereference •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 1CVE-2021-34585 – CODESYS V2 web server: crafted requests could trigger a pointer dereference with an invalid address (DoS)
https://notcve.org/view.php?id=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. En el servidor web de CODESYS V2 versiones anteriores a 1.1.9.22, unas peticiones de servidor web diseñadas pueden desencadenar un error de análisis. Dado que el resultado del analizador no se comprueba en todas las condiciones, puede producirse una desreferencia de puntero con una dirección no válida. • https://customers.codesys.com/index.php?eID=dumpFile&t=f&f=16876&token=a3f1d937f95e7034879f4f2ea8e5a99b168256a7&download= https://www.tenable.com/security/research/tra-2021-47 • CWE-252: Unchecked Return Value •

https://notcve.org/view.php?id=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. Unas peticiones del servidor web diseñadas pueden ser usadas para leer parcialmente la pila o la memoria de la pila o pueden desencadenar una situación de denegación de servicio debido a un bloqueo en el servidor web de CODESYS V2 versiones anteriores a 1.1.9.22 • https://customers.codesys.com/index.php?eID=dumpFile&t=f&f=16876&token=a3f1d937f95e7034879f4f2ea8e5a99b168256a7&download= https://www.tenable.com/security/research/tra-2021-47 • CWE-126: Buffer Over-read •

https://notcve.org/view.php?id=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. Unas peticiones del servidor web diseñadas pueden causar un desbordamiento del búfer en la región heap de la memoria y, por tanto, podrían desencadenar una situación de denegación de servicio debido a un bloqueo en el servidor web de CODESYS V2 versiones anteriores a 1.1.9.22 • https://customers.codesys.com/index.php?eID=dumpFile&t=f&f=16876&token=a3f1d937f95e7034879f4f2ea8e5a99b168256a7&download= https://www.tenable.com/security/research/tra-2021-47 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
