A vulnerability was found in GeekLog 1.3.5 (Blog Software). It has been declared as critical. This vulnerability affects an unknown code block of the file index.php/comment.php. The manipulation of the argument url/topic/title with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-80. The software receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. As an impact it is known to affect confidentiality, integrity, and availability. An attacker might be able to inject arbitrary html and script code into the web site. This would alter the appearance and would make it possible to initiate further attacks against site visitors. CVE summarizes:

Cross-site scripting vulnerabilities in GeekLog 1.3.5 and earlier allow remote attackers to execute arbitrary script via (1) the url variable in the Link field of a calendar event, (2) the topic parameter in index.php, or (3) the title parameter in comment.php.
