3s-Software: >> Codesys Runtime System Security Vulnerabilities
A Stack-based Buffer Overflow issue was discovered in 3S-Smart CODESYS Web Server. Specifically: all Microsoft Windows (also WinCE) based CODESYS web servers running stand-alone Version 2.3, or as part of the CODESYS runtime system running prior to Version V1.1.9.19. A crafted request may cause a buffer overflow and could therefore execute arbitrary code on the web server or lead to a denial-of-service condition due to a crash in the web server.

The Festo CECX-X-C1 Modular Master Controller with CoDeSys and CECX-X-M1
Modular Controller with CoDeSys and SoftMotion provide an undocumented
access method involving the FTP protocol, which could allow a remote attacker to execute arbitrary code or cause a denial of service (application
crash) via unspecified vectors.

The Festo CECX-X-C1 Modular Master Controller with CoDeSys and CECX-X-M1 Modular Controller with CoDeSys and SoftMotion do not require authentication for connections to certain TCP ports, which allows remote attackers to (1) modify the configuration via a request to the debug service on port 4000 or (2) delete log entries via a request to the log service on port 4001.

The Runtime Toolkit in CODESYS Runtime System 2.3.x and 2.4.x does not require authentication, which allows remote attackers to execute commands via the command-line interface in the TCP listener service or transfer files via requests to the TCP listener service.

The CoDeSys Runtime Toolkit’s file transfer functionality does not
perform input validation, which allows an attacker to access files and
directories outside the intended scope. This may allow an attacker to
upload and download any file on the device. This could allow the
attacker to affect the availability, integrity, and confidentiality of
the device.
