CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in ZKTime Web 2.0.1.12280. It has been rated as problematic. Affected by this issue is the function password_change of the file /accounts/password_change/ of the component Modify Password. The manipulation as part of a HTTP Request leads to a cross-site request forgery vulnerability. Using CWE to declare the problem leads to CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. Impacted is integrity. CVE summarizes:

The ZKTime Web Software 2.0.1.12280 allows the Administrator to elevate the privileges of the application user using a 'password_change()' function of the Modify Password component, reachable via the old_password, new_password1, and new_password2 parameters to the /accounts/password_change/ URI. An attacker takes advantage of this scenario and creates a crafted CSRF link to add himself as an administrator to the ZKTime Web Software. He then uses social engineering methods to trick the administrator into clicking the forged HTTP request. The request is executed and the attacker becomes the Administrator of the ZKTime Web Software. If the vulnerability is successfully exploited, then an attacker (who would be a normal user of the web application) can escalate his privileges and become the administrator of ZKTime Web Software.
