Codesys ≫ Control For Empc-a/imx6

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.

A low-privileged remote attacker could exploit the vulnerability and inject additional system commands via file system libraries which could give the attacker full control of the device.

The CODESYS runtime system in multiple versions allows an remote low privileged attacker to use a path traversal vulnerability to access and modify all system files as well as DoS the device.

In CmpBlkDrvTcp of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new TCP connections. Existing connections are not affected.

In CmpChannelServer of CODESYS V3 in multiple versions an uncontrolled ressource consumption allows an unauthorized attacker to block new communication channel connections. Existing connections are not affected.

CODESYS Control runtime system before 3.5.16.10 allows Uncontrolled Memory Allocation.

An issue was discovered in CODESYS Development System before 3.5.16.0. CODESYS WebVisu and CODESYS Remote TargetVisu are susceptible to privilege escalation.

CODESYS V3 web server before 3.5.15.40, as used in CODESYS Control runtime systems, has a buffer overflow.

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.

CODESYS 3 web server before 3.5.15.20, as distributed with CODESYS Control runtime systems, has a Buffer Overflow.
