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 classified as problematic has been found in Cisco Linksys EA6500. This affects an unknown functionality of the component Restore Router Configuration Handler. The manipulation as part of a Backup File leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The software does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability.

The advisory is shared at securityevaluators.com. The public release happened without involvement of Cisco. The attack can only be done within the local network. The successful exploitation needs a authentication. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue. The advisory points out:

The Linksys EA6500 does not properly validate configuration files that are uploaded through the web management interface. With some social engineering and a malicious configuration file, an attacker and gain shell access to the Linksys EA6500.
