CVE-2024-39182 Overview
CVE-2024-39182 is an information disclosure vulnerability in ISPmanager v6.98.0, a commercial web hosting control panel. The flaw allows attackers to access sensitive details of the root user's session through an arbitrary command, tracked internally as ISP6-1779. The issue is categorized under [CWE-200] (Exposure of Sensitive Information to an Unauthorized Actor). Successful exploitation exposes session data tied to the highest-privileged account on the host, providing attackers with material that can support further compromise of the managed server.
Critical Impact
Remote attackers can retrieve sensitive root session details from ISPmanager v6.98.0 over the network without authentication or user interaction, undermining administrative trust boundaries on hosting servers.
Affected Products
- ISPmanager v6.98.0
- ISPmanager 6 deployments prior to the vendor's corrective release
- Hosting environments managed through the affected control panel build

Technical Details for CVE-2024-39182
Vulnerability Analysis
The vulnerability resides in ISPmanager v6.98.0 and is reachable over the network. An attacker issues an arbitrary command against the control panel and receives session-related data belonging to the root user in the response. Because ISPmanager runs with elevated privileges to manage hosting tasks, root session details are a high-value target for adversaries who chain disclosures into session takeover.
The weakness aligns with [CWE-200], where the application returns more information than the requesting context should be allowed to see. The affected request path does not properly partition output between administrative state and the data exposed to a network caller.
Root Cause
The root cause is improper restriction of sensitive data returned by an internal command handler in ISPmanager. The handler exposes attributes of the active root session rather than confining its output to non-sensitive operational data. The vendor's change log entry referenced as ISP6-1779 corresponds to the corrective fix in the ISPmanager Change Log.
Attack Vector
The attack vector is network-based with low complexity and requires no privileges or user interaction. An attacker who can reach the ISPmanager web interface submits the arbitrary command and parses the response for root session identifiers. The vulnerability impacts confidentiality only; it does not directly enable code execution or modification of data, though disclosed session material may be reused in follow-on attacks against the panel.
No public proof-of-concept code or exploit module is currently documented in the references for this CVE. Administrators should treat the issue as exploitable in any environment that exposes ISPmanager to untrusted networks. See the ISPmanager Change Log for the vendor's technical notes.
Detection Methods for CVE-2024-39182
Indicators of Compromise
- Unexpected HTTP requests to ISPmanager command endpoints originating from external or unmanaged IP addresses.
- Access log entries showing repeated calls to control-panel command parameters outside normal administrator workflows.
- Concurrent root sessions or session reuse from geographically inconsistent source addresses.
Detection Strategies
- Inspect ISPmanager access logs for requests that invoke command parameters without an associated authenticated administrative workflow.
- Correlate web server logs with panel session activity to flag responses containing session identifiers returned to unauthenticated clients.
- Alert on responses from the panel that exceed expected size for command endpoints, which may indicate session data leakage.
Monitoring Recommendations
- Forward ISPmanager and reverse-proxy logs into a centralized analytics platform with retention sufficient for retroactive hunting.
- Monitor for use of root session tokens from new source IP addresses or user agents.
- Track configuration changes in /usr/local/mgr5/ and related ISPmanager paths to detect post-exploitation tampering.
How to Mitigate CVE-2024-39182
Immediate Actions Required
- Upgrade ISPmanager to a version newer than v6.98.0 that includes the fix referenced as ISP6-1779.
- Restrict access to the ISPmanager web interface to trusted administrative IP ranges using firewall or reverse-proxy rules.
- Invalidate active root sessions and rotate administrative credentials after patching.
Patch Information
The vendor addressed the issue in a subsequent ISPmanager 6 release. Review the ISPmanager Change Log for the build that incorporates the ISP6-1779 fix and follow the documented upgrade procedure for your deployment.
Workarounds
- Place ISPmanager behind a VPN or bastion host so the panel is not directly exposed to the internet.
- Apply strict IP allow-lists at the reverse proxy or host firewall for the panel's listening port.
- Disable or block the affected command endpoints at the proxy layer until the patched version is deployed.
# Configuration example: restrict ISPmanager access with iptables
iptables -A INPUT -p tcp --dport 1500 -s 203.0.113.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 1500 -j DROP
