ManageEngine ServiceDesk Plus MSP Security Advisory

This is a security advisory regarding possible Integer/Heap Overflow - Remote Code Execution (RCE) and Remote Denial of Service vulnerabilities in ServiceDesk Plus MSP and Remote AssetExplorer (software used for distributed asset scans), which have been identified and rectified.

Users of ServiceDesk Plus MSP (Professional and Enterprise editions) with versions up to 10525 and using the distributed asset scanning agents from Remote AssetExplorer might be affected by the vulnerabilities and are advised to update to the latest version (10526) immediately.

Severity: High

Impact:

The Integer/Heap Overflow - RCE vulnerability allows an attacker to send a new scan request to a listening agent on the network and also receive the agent's HTTP request verifying its authtoken. The agent reaching out over HTTP makes it vulnerable to an integer overflow, which can be turned into a heap overflow if the POST payload response is too large. This allows for RCE as NT AUTHORITY/SYSTEM on the agent machine.

The Remote Denial of Service vulnerability might be exploited to repetitively send commands to the Remote AssetExplorer agent, which listens on port 9000 for incoming commands over HTTPS from the ManageEngine server. While these commands may not be executed, the Remote AssetExplorer agent reaches out to the ManageEngine server for an HTTP request, which results in a memory leak. These memory leaks allow a remote attacker to send commands to the agent repetitively and eventually crash the agent due to an out-of-memory condition.

What led to the vulnerabilities?

The Integer/Heap Overflow - RCE vulnerability was caused by ServiceDesk Plus MSP's distributed asset scan agent, Remote AssetExplorer, not validating HTTPS certificates, which allows an attacker on the network to statically configure their IP address to match the ServiceDesk Plus MSP server's IP address.

The Remote Denial of Service vulnerability was caused by HTTPS certificates not being verified, which allows any arbitrary user on the network to send commands over port 9000.

Moreover, ServiceDesk Plus MSP (up to version 10525) allowed vulnerable agents to be downloaded from the product UI itself.

Who is affected?

These vulnerabilities affect customers of the Professional and Enterprise editions of ServiceDesk Plus MSP using versions up to 10525 and using the product’s distributed asset scanning agents.

How have we fixed them?

Both vulnerabilities are resolved in ServiceDesk Plus MSP 10526. In ServiceDesk Plus MSP, we have removed the built-in remote agent support, and agent-based scanning can no longer be performed directly from ServiceDesk Plus MSP; instead, all agents must push data through Remote AssetExplorer servers.

Remote AssetExplorer has adopted Desktop Central's unified agent for asset discovery. You can download the compatible Remote AssetExplorer build here. (Note: This Remote AssetExplorer build is compatible only with the latest version, i.e., ServiceDesk Plus MSP 10526 and above.)

How to find out if you are affected

Click the Help link in the top-right corner of the ServiceDesk Plus MSP web client. Select the About option from the drop-down to see your current version. If your current version (Professional and Enterprise editions) is 10525 or below and you are using the asset scanning agent in ServiceDesk Plus MSP, you might be affected.

What customers should do

Customers who fit the above criteria can upgrade to the latest version (10526) using the appropriate migration path here.

Please read the upgrade instructions carefully before beginning the upgrade. For assistance, write to support@servicedeskplusmsp.com or call us toll-free at +1.888.720.9500.

Important note:

As always, make a copy of the entire ServiceDesk Plus MSP installation folder before applying the upgrade, and keep the copy in a separate location.

ManageEngine ServiceDesk Plus MSP Security Advisory

This is a security advisory regarding possible Integer/Heap Overflow - Remote Code Execution (RCE) and Remote Denial of Service vulnerabilities in ServiceDesk Plus MSP and Remote AssetExplorer (software used for distributed asset scans), which have been identified and rectified.

Users of ServiceDesk Plus MSP (Professional and Enterprise editions) with versions up to 10525 and using the distributed asset scanning agents from Remote AssetExplorer might be affected by the vulnerabilities and are advised to update to the latest version (10526) immediately.

Severity: High

Impact:

The Integer/Heap Overflow - RCE vulnerability allows an attacker to send a new scan request to a listening agent on the network and also receive the agent's HTTP request verifying its authtoken. The agent reaching out over HTTP makes it vulnerable to an integer overflow, which can be turned into a heap overflow if the POST payload response is too large. This allows for RCE as NT AUTHORITY/SYSTEM on the agent machine.

The Remote Denial of Service vulnerability might be exploited to repetitively send commands to the Remote AssetExplorer agent, which listens on port 9000 for incoming commands over HTTPS from the ManageEngine server. While these commands may not be executed, the Remote AssetExplorer agent reaches out to the ManageEngine server for an HTTP request, which results in a memory leak. These memory leaks allow a remote attacker to send commands to the agent repetitively and eventually crash the agent due to an out-of-memory condition.

What led to the vulnerabilities?

The Integer/Heap Overflow - RCE vulnerability was caused by ServiceDesk Plus MSP's distributed asset scan agent, Remote AssetExplorer, not validating HTTPS certificates, which allows an attacker on the network to statically configure their IP address to match the ServiceDesk Plus MSP server's IP address.

The Remote Denial of Service vulnerability was caused by HTTPS certificates not being verified, which allows any arbitrary user on the network to send commands over port 9000.

Moreover, ServiceDesk Plus MSP (up to version 10525) allowed vulnerable agents to be downloaded from the product UI itself.

Who is affected?

These vulnerabilities affect customers of the Professional and Enterprise editions of ServiceDesk Plus MSP using versions up to 10525 and using the product’s distributed asset scanning agents.

How have we fixed them?

Both vulnerabilities are resolved in ServiceDesk Plus MSP 10526. In ServiceDesk Plus MSP, we have removed the built-in remote agent support, and agent-based scanning can no longer be performed directly from ServiceDesk Plus MSP; instead, all agents must push data through Remote AssetExplorer servers.

Remote AssetExplorer has adopted Endpoint Central (formerly Desktop Central)'s unified agent for asset discovery. You can download the compatible Remote AssetExplorer build here.

If anything goes wrong during the upgrade, you'll have this copy as a backup, which will keep all your settings intact. If you're using a MS SQL server as a back-end database, back up the ServiceDesk Plus MSP database before applying the upgrade. Once the upgrade is successfully completed, remember to delete the backup.

We offer our sincerest apologies for any inconvenience this may have caused.

Thanks,
Umasankar
ServiceDesk Plus MSP team.
