Name of the Vulnerable Software and Affected Versions 3S-Smart CODESYS Web Server version 2.3 3S-Smart CODESYS Web Server versions prior to V1.1.9.19

Description A Stack-based Buffer Overflow issue was discovered in the 3S-Smart CODESYS Web Server. This issue can be exploited by a crafted request, potentially causing a buffer overflow, which could lead to the execution of arbitrary code on the web server or result in a denial-of-service condition due to a crash in the web server.

Recommendations For version 2.3, update to a version newer than V1.1.9.19 to resolve the issue. For versions prior to V1.1.9.19, update to version V1.1.9.19 or newer to resolve the issue. As a temporary workaround, consider restricting access to the web server to minimize the risk of exploitation.
