Eggblog is prone to multiple input validation vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input.
Successful exploitation of these vulnerabilities could result in a compromise of the application, disclosure or modification of data, the theft of cookie-based authentication credentials. They may also permit an attacker to exploit vulnerabilities in the underlying database implementation. An attacker could also exploit this issue to control how the site is rendered to the user; other attacks are also possible.
