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, which was classified as critical, has been found in Lepton CMS 2.2.2 (Content Management System). This issue affects some unknown processing of the file /LEPTON_stable_2.2.2/upload/admins/pages/add.php of the component Create Page. The manipulation of the argument parent with the input value 0 union select version() leads to a sql injection vulnerability (Blind). Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability.

The weakness was released 11/17/2016 by Tim Coen with Curesec Research Team as Lepton 2.2.2: SQL Injection as confirmed mailinglist post (Full-Disclosure). The advisory is shared at seclists.org. The public release was coordinated with Lepton. The attack may be initiated remotely. Required for exploitation is a simple authentication. Technical details as well as a public exploit are known.
