CVE-2020-36926: SmarterTrack Information Disclosure Flaw

CVE-2020-36926 Overview

CVE-2020-36926 is an information disclosure vulnerability affecting SmarterTrack version 7922, a customer service and help desk platform developed by SmarterTools. The vulnerability exists in the Chat Management search form, allowing unauthenticated attackers to access sensitive agent identification details through a network-accessible endpoint.

The vulnerable endpoint /Management/Chat/frmChatSearch.aspx improperly exposes agent information without requiring authentication. When accessed, this endpoint reveals agents' first and last names along with their unique identifiers, which could be leveraged for further attacks such as social engineering, targeted phishing campaigns, or enumeration of internal personnel.

Critical Impact

Unauthenticated attackers can remotely enumerate support agent identities and unique identifiers, enabling targeted social engineering attacks and reconnaissance activities against organizations using SmarterTrack.

Affected Products

• SmarterTrack version 7922
• SmarterTools SmarterTrack Chat Management module
• Organizations using vulnerable SmarterTrack deployments with exposed management interfaces

Technical Details for CVE-2020-36926

Vulnerability Analysis

This vulnerability is classified under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere). The Chat Management search functionality fails to implement proper access controls, allowing any network-adjacent or remote attacker to query the endpoint and retrieve agent details that should remain confidential.

The information disclosure occurs because the application does not verify whether the requesting user has appropriate privileges to access the Chat Management search form. This architectural weakness means that sensitive internal data—specifically agent names and unique identifiers—can be harvested by anyone who can reach the endpoint.

The attack requires no user interaction and can be executed with low complexity. While the vulnerability only permits read access to confidential data (no integrity or availability impact), the exposed information could serve as reconnaissance data for more sophisticated attacks.

Root Cause

The root cause of CVE-2020-36926 is insufficient authorization controls on the /Management/Chat/frmChatSearch.aspx endpoint. The application fails to validate that requests to this administrative search form originate from authenticated and authorized users, resulting in exposure of sensitive system information.

This represents a broken access control flaw where the management interface component lacks the necessary authentication checks that should gate access to internal personnel data.

Attack Vector

Exploitation of this vulnerability occurs via network access. An attacker can directly request the vulnerable endpoint from any location with network connectivity to the SmarterTrack instance. The attack flow involves:

1. Identifying a SmarterTrack installation exposed to the network
2. Navigating to the /Management/Chat/frmChatSearch.aspx endpoint
3. Querying the search form to retrieve agent identification information
4. Harvesting agent names and unique identifiers for use in subsequent attacks

The vulnerability can be exploited through standard HTTP requests without any special tools or authentication credentials. For detailed technical information regarding this vulnerability, refer to the Exploit-DB entry #50328 and the VulnCheck Advisory.

Detection Methods for CVE-2020-36926

Indicators of Compromise

• Unusual or unauthorized HTTP requests to /Management/Chat/frmChatSearch.aspx from external IP addresses
• Multiple sequential requests to the Chat Management endpoint indicating enumeration attempts
• Web server logs showing access patterns targeting management interfaces from unauthenticated sources

Detection Strategies

• Configure web application firewall (WAF) rules to alert on access attempts to /Management/Chat/frmChatSearch.aspx from non-whitelisted sources
• Implement network intrusion detection signatures to identify reconnaissance activity against SmarterTrack management endpoints
• Deploy endpoint detection and response (EDR) solutions to monitor for anomalous web traffic patterns targeting help desk infrastructure

Monitoring Recommendations

• Enable detailed access logging on SmarterTrack management endpoints and forward logs to SIEM solutions
• Establish baseline traffic patterns for management interfaces and configure alerts for deviations
• Regularly audit access logs for the /Management/Chat/ directory to identify potential exploitation attempts

How to Mitigate CVE-2020-36926

Immediate Actions Required

• Restrict network access to SmarterTrack management interfaces using firewall rules or network segmentation
• Implement IP whitelisting for administrative endpoints to limit access to trusted sources only
• Review web server configurations to ensure management paths are not exposed to public networks
• Audit existing access logs for evidence of prior exploitation attempts

Patch Information

Organizations should check for updates from SmarterTools that address this information disclosure vulnerability. Visit the SmarterTools Official Site or the SmarterTrack Product Page for the latest security patches and version updates.

For additional vulnerability details, consult the VulnCheck Advisory on SmarterTrack.

Workarounds

• Block external access to the /Management/ directory tree at the web server or reverse proxy level
• Place SmarterTrack management interfaces behind a VPN or zero-trust network access solution
• Implement authentication requirements at the web server level (e.g., HTTP Basic Authentication) as an additional layer of protection for management endpoints

# Example IIS URL Rewrite rule to block external access to management endpoints
# Add to web.config in the SmarterTrack root directory
<rule name="Block Management Access" stopProcessing="true">
    <match url="^Management/.*" />
    <conditions>
        <add input="{REMOTE_ADDR}" pattern="^(192\.168\.|10\.|172\.(1[6-9]|2[0-9]|3[01])\.)" negate="true" />
    </conditions>
    <action type="CustomResponse" statusCode="403" statusReason="Forbidden" statusDescription="Access Denied" />
</rule>
