5.3CVE-2025-2595codesyscodesys visualization
EPSS score
0.46%
An unauthenticated remote attacker can bypass the user management in CODESYS Visualization and read visualization template files or static elements by means of forced browsing.
7.5CVE-2025-1468codesyscodesys runtime toolkit
EPSS score
0.64%
An unauthenticated remote attacker can gain access to sensitive information including authentication information when using CODESYS OPC UA Server with the non-default Basic128Rsa15 security policy.
8.3CVE-2025-41659codesyscontrol_for_beaglebone_sl+15
EPSS score
0.22%
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.
5.5CVE-2025-41658codesyscontrol_for_beaglebone_sl+11
EPSS score
0.12%
CODESYS Runtime Toolkit-based products may expose sensitive files to local low-privileged operating system users due to default file permissions.
8.8CVE-2025-41660codesyscodesys control for beaglebone sl+15
EPSS score
0.43%
A low-privileged remote attacker may be able to replace the boot application of the CODESYS Control runtime system, enabling unauthorized code execution.
5.9CVE-2025-41739codesyscodesys control for beaglebone sl+15
EPSS score
0.35%
An unauthenticated remote attacker, who beats a race condition, can exploit a flaw in the communication servers of the CODESYS Control runtime system on Linux and QNX to trigger an out-of-bounds read via crafted socket communication, potentially causing a denial of service.
7.5CVE-2025-41738codesyscodesys control for beaglebone sl+33
EPSS score
0.39%
An unauthenticated remote attacker may cause the visualisation server of the CODESYS Control runtime system to access a resource with a pointer of wrong type, potentially leading to a denial-of-service (DoS) condition.
7.5CVE-2025-41691codesyscontrol_for_beaglebone_sl+14
EPSS score
0.55%
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.
7.8CVE-2025-41700codesyscodesys+1
EPSS score
0.15%
An unauthenticated attacker can trick a local user into executing arbitrary code by opening a deliberately manipulated CODESYS project file with a CODESYS development system. This arbitrary code is executed in the user context.
6.6CVE-2025-0694codesyscodesys control for beaglebone sl+14
EPSS score
0.28%
Insufficient path validation in CODESYS Control allows low privileged attackers with physical access to gain full filesystem access.
6.5CVE-2020-7052codesyscontrol_for_beaglebone+14
EPSS score
1.88%
CODESYS Control V3, Gateway V3, and HMI V3 before 3.5.15.30 allow uncontrolled memory allocation which can result in a remote denial of service condition.
10CVE-2020-10245codesyscontrol_for_beaglebone+13
EPSS score
2.50%
CODESYS V3 web server before 3.5.15.40, as used in CODESYS Control runtime systems, has a buffer overflow.
7.5CVE-2020-15806codesyscontrol_for_beaglebone+15
EPSS score
2.05%
CODESYS Control runtime system before 3.5.16.10 allows Uncontrolled Memory Allocation.
9.9CVE-2020-6081codesysruntime
EPSS score
1.76%
An exploitable code execution vulnerability exists in the PLC_Task functionality of 3S-Smart Software Solutions GmbH CODESYS Runtime 3.5.14.30. A specially crafted network request can cause remote code execution. An attacker can send a malicious packet to trigger this vulnerability.
7.8CVE-2020-12069codesyscodesys v3 containing the cmpusermgr+64
EPSS score
0.17%
In CODESYS V3 products in all versions prior V3.5.16.0 containing the CmpUserMgr, the CODESYS Control runtime system stores the online communication passwords using a weak hashing algorithm. This can be used by a local attacker with low privileges to gain full control of the device.
6.5CVE-2020-12068codesyscontrol_for_beaglebone+11
EPSS score
0.94%
An issue was discovered in CODESYS Development System before 3.5.16.0. CODESYS WebVisu and CODESYS Remote TargetVisu are susceptible to privilege escalation.
5.3CVE-2022-1989codesyscodesys visualization+1
EPSS score
0.86%
All CODESYS Visualization versions before V4.2.0.0 generate a login dialog vulnerable to information exposure allowing a remote, unauthenticated attacker to enumerate valid users.
5.5CVE-2022-1794codesyscodesys opc da server+1
EPSS score
0.21%
The CODESYS OPC DA Server prior V3.5.18.20 stores PLC passwords as plain text in its configuration file so that it is visible to all authorized Microsoft Windows users of the system.
8.1CVE-2022-1965codesysplcwinnt+1
EPSS score
1.05%
Multiple products of CODESYS implement a improper error handling. A low privilege remote attacker may craft a request, which is not properly processed by the error handling. In consequence, the file referenced by the request could be deleted. User interaction is not required.
8.8CVE-2022-47380codesyscodesys control for beaglebone sl+33
EPSS score
1.32%
An authenticated remote attacker may use a stack based  out-of-bounds write vulnerability in multiple CODESYS products in multiple versions to write data into the stack which can lead to a denial-of-service condition, memory overwriting, or remote code execution.
