CVE-2006-3838: eIQnetworks ESA stack buffer overflows via daemon commands

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 18 September 2026. Confidence: high.

critical priorityCVSS 10.0 with network reachability, no authentication, and very high EPSS make this a top-priority remote code execution risk for exposed ESA deployments.

What it is

eIQnetworks Enterprise Security Analyzer (ESA) before 2.5.0 contains multiple stack-based buffer overflows in its Syslog, Topology, License Manager, and Monitoring components. Remote attackers can send long command arguments to these daemons to overwrite stack memory and execute arbitrary code. The flaw affects ESA and several OEM products that embed it, including Sidewinder, iPolicy Security Manager, Astaro Report Manager, Fortinet FortiReporter, and Top Layer Network Security Analyzer.

Impact

An unauthenticated remote attacker can execute arbitrary code with the privileges of the affected service, potentially taking full control of the host. Because the vulnerable services are network-facing, this can lead to complete compromise of the ESA deployment and any managed security data.

Attack surface

The flaw is reached over the network by sending crafted commands to the Syslog daemon (syslogserver.exe), Topology server (Topology.exe), License Manager (EnterpriseSecurityAnalyzer.exe), or Monitoring agent (Monitoring.exe). The CVSS vector AV:N/AC:L/Au:N indicates no authentication or user interaction is required.

Exploitation

The record is not listed in CISA KEV and no ransomware associations are documented, but EPSS is very high (0.73562, 99.4th percentile), indicating a strong likelihood of exploitation activity. Reference tags are limited to vendor advisories and government resources, with no public exploit tag supplied.

What to do

• Upgrade eIQnetworks ESA to version 2.5.0 or later as documented in the vendor release notes.
• Apply the corresponding updates for OEM products that embed ESA (Sidewinder, iPolicy Security Manager, Astaro Report Manager, Fortinet FortiReporter, Top Layer Network Security Analyzer).
• Restrict network access to the Syslog, Topology, License Manager, and Monitoring services to trusted management hosts only.
• If immediate patching is not possible, isolate or disable the affected daemons until the upgrade can be performed.
• Monitor vendor advisories for any additional affected products or follow-up patches.

Detection

• Inspect network traffic to the affected daemon ports for unusually long command arguments matching the vulnerable command names (DELTAINTERVAL, LOGFOLDER, DELETELOGS, FWASERVER, SYSLOGPUBLICIP, GETFWAIMPORTLOG, GETFWADELTA, DELETERDEPDEVICE, COMPRESSRAWLOGFILE, GETSYSLOGFIREWALLS, ADDPOLICY, EDITPOLICY, GUIADDDEVICE, ADDDEVICE, DELETEDEVICE, LICMGR_ADDLICENSE, TRACE, QUERYMONITOR).
• Monitor process crashes or unexpected restarts of syslogserver.exe, Topology.exe, EnterpriseSecurityAnalyzer.exe, and Monitoring.exe.
• Review host logs for suspicious child processes spawned by the ESA services, which may indicate successful code execution.
• Use IDS/IPS signatures for stack buffer overflow attempts against the ESA daemons if available.
