Pi3Web HTTP Server long CGI parameter buffer overflow
|pi3web-long-parameter-bo (7880)||Low Risk|
Pi3Web HTTP Server is vulnerable to a denial of service attack, caused by a buffer overflow in the handling of CGI parameters. By sending several URL requests containing overly long CGI parameter values, a remote attacker can overflow a buffer and cause the Web server to crash. The server must be restarted to regain normal functionality.
Denial of Service
Upgrade to the latest version of Pi3Web (2.0.0 or later), available from the SourceForge Web site. See References.
