Frauscher Diagnostic System FDS001 for FAdC R1 and FAdCi R1 v1.3.3 and all previous versions are vulnerable to a path traversal vulnerability of the web interface by a crafted URL without authentication.
An authenticated attacker can send a malformed packet to trigger a device crash via the CODESYS V2 runtime commands parsing.
An unauthenticated attacker with network access to port 502/TCP of the target device can cause a denial-of-service condition by sending multiple specially crafted packets. The MODBUS server does not properly release memory resources that were reserved for incomplete connection attempts by MODBUS clients. This could allow a remote attacker to generate a denial of service condition on devices that incorporate a vulnerable version of the MODBUS server.
The FL MGUARD family of devices is affected by two vulnerabilities.
Two vulnerabilites have been discovered in myREX24 and myREX24.virtual in all versions through 2.13.3.
Two vulnerabilites have been discovered in mbCONNECT24 and mbCONNECT24 in all versions through 2.13.3.
The “legal information” plugin of web-based-management contained a vulnerability which allowed execution of arbitrary commands with privileges of www user.
