Titel:	Embedthis GoAhead < 3.6.5 RCE Vulnerability - Active Check
Zusammenfassung:	Embedthis GoAhead is prone to a remote code execution (RCE); vulnerability.
Beschreibung:	Summary: Embedthis GoAhead is prone to a remote code execution (RCE) vulnerability. Vulnerability Insight: Embedthis GoAhead allows remote code execution if CGI is enabled and a CGI program is dynamically linked. This is a result of initializing the environment of forked CGI scripts using untrusted HTTP request parameters in the cgiHandler function in cgi.c. When combined with the glibc dynamic linker, this behaviour can be abused for remote code execution using special parameter names such as LD_PRELOAD. An attacker can POST their shared object payload in the body of the request, and reference it using /proc/self/fd/0. Vulnerability Impact: An unauthenticated attacker may execute arbitrary code. Affected Software/OS: Embedthis GoAhead versions prior to 3.6.5. Solution: Updated to version 3.6.5 or later. As a migitation step disable CGI support.
