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.CVE-2021-34583codesyscodesys+28EPSS score8.84%
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-2021-34578wago750-362_firmware+12EPSS score0.96%
This vulnerability allows an attacker who has access to the WBM to read and write settings-parameters of the device by sending specifically constructed requests without authentication on multiple WAGO PLCs in firmware versions up to FW07.CVE-2021-34569wago750-8100_firmware+54EPSS score0.87%
In WAGO I/O-Check Service in multiple products an attacker can send a specially crafted packet containing OS commands to crash the diagnostic tool and write memory.CVE-2021-34595codesyscodesys+30EPSS score0.85%
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.CVE-2021-34568wago750-8100_firmware+54EPSS score1.11%
In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to provoke a denial of service.CVE-2021-34584codesyscodesys+28EPSS score1.08%
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.CVE-2021-34567wago750-8100_firmware+54EPSS score0.86%
In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to provoke a denial of service and an limited out-of-bounds read.CVE-2021-34593codesyscodesys v2+15EPSS score2.66%
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.CVE-2021-34586codesyscodesys+28EPSS score13.74%
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-2021-34566wago750-8100_firmware+54EPSS score1.15%
In WAGO I/O-Check Service in multiple products an unauthenticated remote attacker can send a specially crafted packet containing OS commands to crash the iocheck process and write memory resulting in loss of integrity and DoS.CVE-2021-34581wago750-831_firmware+9EPSS score1.02%
Missing Release of Resource after Effective Lifetime vulnerability in OpenSSL implementation of WAGO 750-831/xxx-xxx, 750-880/xxx-xxx, 750-881, 750-889 in versions FW4 up to FW15 allows an unauthenticated attacker to cause DoS on the device.CVE-2021-34585codesyscodesys+28EPSS score0.90%
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.CVE-2015-10123wagocontroller bacnet ms/tp+3EPSS score0.64%
An unautheticated remote attacker could send specifically crafted packets to a affected device. If an authenticated user then views that data in a specific page of the web-based management a buffer overflow will be triggered to gain full access of the device.
