Name of the Vulnerable Software and Affected Versions TOTOLINK T6 version 4.1.5cu.748 B20211015
Description Incorrect access control in the showSyslog() function allows unauthenticated attackers to retrieve recent system logs. This is achieved by sending a crafted POST request to the '/cgi-bin/cstecgi.cgi' endpoint.
Recommendations As a temporary workaround, restrict access to the '/cgi-bin/cstecgi.cgi' endpoint or disable the showSyslog() function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
