Name of the Vulnerable Software and Affected Versions PLANET GS-4210-16P2S versions prior to 3.441b260626
Description Authenticated stack buffer overflows exist in the '/cgi-bin/dispatcher.cgi' endpoint. The issue occurs because the following handlers copy POST parameters into fixed-size stack buffers without proper length validation:
  • web login first post handler copies the usrPass parameter.
  • web sys enablePasswd post handler copies the enbPass parameter.
  • web sys localUser post handler copies the usrName and usrPass parameters.
A remote authenticated attacker can send a crafted request to crash the CGI process or web management service, leading to a denial of service.
Recommendations Update to version 3.441b260626 or later.
