https://notcve.org/view.php?id=CVE-2019-5184
An exploitable double free vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC 200. A specially crafted XML cache file written to a specific location on the device can cause a heap pointer to be freed twice, resulting in a denial of service and potentially code execution. An attacker can send a specially crafted packet to trigger the parsing of this cache file. Se presenta una vulnerabilidad de doble liberación explotable en la funcionalidad "I/O-Check" del servicio iocheckd de WAGO PFC 200. Un archivo caché XML especialmente diseñado y escrito en una ubicación específica en el dispositivo puede causar que un puntero de la pila sea dos veces liberado, resultando en un denegación de servicio y potencialmente en ejecución de código. • https://talosintelligence.com/vulnerability_reports/TALOS-2019-0965 • CWE-415: Double Free •
CVE-2019-5186
https://notcve.org/view.php?id=CVE-2019-5186
An exploitable stack buffer overflow vulnerability vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC 200. An attacker can send a specially crafted packet to trigger the parsing of this cache file.At 0x1eb9c the extracted interface element name from the xml file is used as an argument to /etc/config-tools/config_interfaces interface=<contents of interface element> using sprintf(). The destination buffer sp+0x40 is overflowed with the call to sprintf() for any interface values that are greater than 512-len("/etc/config-tools/config_interfaces interface=") in length. Later, at 0x1ea08 strcpy() is used to copy the contents of the stack buffer that was overflowed sp+0x40 into sp+0x440. The buffer sp+0x440 is immediately adjacent to sp+0x40 on the stack. • https://talosintelligence.com/vulnerability_reports/TALOS-2019-0966 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVE-2019-5181
https://notcve.org/view.php?id=CVE-2019-5181
An exploitable stack buffer overflow vulnerability vulnerability exists in the iocheckd service ‘I/O-Check’ functionality of WAGO PFC 200 Firmware version 03.02.02(14). A specially crafted XML cache file written to a specific location on the device can cause a stack buffer overflow, resulting in code execution. An attacker can send a specially crafted packet to trigger the parsing of this cache file. The destination buffer sp+0x440 is overflowed with the call to sprintf() for any subnetmask values that are greater than 1024-len(‘/etc/config-tools/config_interfaces interface=X1 state=enabled subnet-mask=‘) in length. A subnetmask value of length 0x3d9 will cause the service to crash. • https://talosintelligence.com/vulnerability_reports/TALOS-2019-0963 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-5180
An exploitable stack buffer overflow vulnerability vulnerability exists in the iocheckd service ‘I/O-Check’ functionality of WAGO PFC 200 Firmware version 03.02.02(14). An attacker can send a specially crafted packet to trigger the parsing of this cache file. The destination buffer sp+0x440 is overflowed with the call to sprintf() for any ip values that are greater than 1024-len(‘/etc/config-tools/config_interfaces interface=X1 state=enabled ip-address=‘) in length. A ip value of length 0x3da will cause the service to crash. Se presenta una vulnerabilidad de desbordamiento del búfer de la pila explotable en la funcionalidad "I-O-Check" del servicio iocheckd de WAGO PFC 200, versiones de Firmware 03.02.02(14). • https://talosintelligence.com/vulnerability_reports/TALOS-2019-0963 • CWE-787: Out-of-bounds Write •
