>> Hogstorps Guestbook Authentication Bypass and Cross Site Scripting Vulnerabilities
|
Two vulnerabilities have been identified in Hogstorps Guestbook, which could be exploited by attackers to gain unauthorizd access or execute arbitrary scripting code.
The first flaw is due to authentication errors in "admin/radera/tabort.asp" and "admin/redigera/redigera2.asp", which could be exploited by attackers to edit or delete arbitrary entries.
The second issue is due to input validation errors in the "add.asp" script that does not validate certain parameters, which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser in the security context of an affected Web site.
