3S CODESYS V3 CmpWebServer Multiple Vulnerabilities

High Nessus Plugin ID 129469

Synopsis

A 3S CODESYS V3 environment on the remote host is affected by multiple vulnerabilities.

Description

The 3S CODESYS V3 environment running on the remote host is affected by multiple vulnerabilities :

- A directory traversal vulnerability exists in the web server (CmpWebServer) due to improper validation of user-supplied data. An unauthenticated, remote attacker can exploit this, by sending a URI that contains directory traversal characters, to disclose the contents of files located outside of the server's restricted path. (CVE-2019-13532)

- A stack-based buffer overflow condition exists in the web server (CmpWebServer) due to improper validation of user-supplied data. An unauthenticated, remote attacker can exploit this, via a specially crafted HTTP request, to cause a denial of service condition or the execution of arbitrary code. (CVE-2019-13548)

Solution

Upgrade 3S CODESYS V3 environment to version 3.5.14.10 or higher.
