|---|---|---|
| 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 est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
Score EPSS
Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.
Percentile EPSS
Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

Here is the Vulnerability code in /bbs/tb.php
-----------------------vul code-------------------
//bbs/tb.php
$arr = explode("/", $_SERVER[PATH_INFO]);
//$_SERVER[PATH_INFO] is not affected by the magic_quotes_gpc set of php
//we can inject arbitrary sql code include single quotes through $_SERVER[PATH_INFO]
$bo_table = $arr[1];
$wr_id = $arr[2];
$to_token = $arr[3];
//we can pass arbitrary sql code to $bo_table
$write_table = $g4[write_prefix] . $bo_table;
// $write_table can be injected through $bo_table
$sql = " select wr_id, ca_name, wr_email from $write_table where wr_id = '$wr_id' ";
//here $write_table lead to sql injection,and no need of single quotes
$wr = sql_fetch($sql, FALSE);
if (!$wr[wr_id] || !($_POST[title] && $_POST[excerpt] && $_POST[url] && $_POST[blog_name]))
{
$tmp_dir = str_replace("/tb.php", "", $_SERVER[SCRIPT_NAME]);
header("location:$tmp_dir/board.php?bo_table=$bo_table&wr_id=$wr_id");
exit;
