|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 problematic, has been found in pfSense 2.4.4-p2/2.4.4-p3 (Firewall Software). This issue affects an unknown functionality of the file diag_command.php. The manipulation of the argument
timePeriod as part of a Parameter leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. Impacted is integrity. 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. The summary by CVE is:
In pfSense 2.4.4-p2 and 2.4.4-p3, if it is possible to trick an authenticated administrator into clicking on a button on a phishing page, an attacker can leverage XSS to upload arbitrary executable code, via diag_command.php and rrd_fetch_json.php (timePeriod parameter), to a server. Then, the remote attacker can run any command with root privileges on that server.
The weakness was published 06/25/2019. The identification of this vulnerability is CVE-2019-12949 since 06/24/2019. The attack may be initiated remotely. The successful exploitation needs a simple authentication. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1059.007 for this issue.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
