Security readout for executives and security teams
Plain-English summary
CVE-2018-25159 is a critical remote code execution issue in Epross AVCON6. An unauthenticated attacker could abuse the login.action endpoint to run operating-system commands, reportedly with root privileges. This creates high business risk if AVCON6 is reachable from untrusted networks.
Executive priority
Prioritize immediately for exposed AVCON6 systems. The issue allows unauthenticated command execution with full system impact, and public exploit information exists. If AVCON6 is not externally reachable, prioritize rapid validation and network restriction.
Technical view
The vulnerability is described as OGNL injection through the redirect parameter of login.action. The CVSS 3.1 score is 9.8: network-accessible, low complexity, no authentication, and high confidentiality, integrity, and availability impact. Public references include a VulnCheck advisory and ExploitDB entry.
Likely exposure
Highest exposure is AVCON6 systems reachable from the internet or broad internal networks. The source bundle does not provide precise vulnerable version ranges beyond AVCON6, and the affected-version data is incomplete or inconsistent.
Exploitation context
A public ExploitDB reference exists, but the provided sources do not show CISA KEV listing or confirmed active exploitation. Treat this as readily researchable and high priority because exploitation requires no authentication according to the CVE description.
Researcher notes
Evidence supports critical unauthenticated OGNL injection in AVCON6 login.action. The bundle does not include vendor patch details, exact affected versions, or proof of active exploitation. Avoid assuming all versions are affected beyond the provided AVCON6 product statement.
Mitigation direction
- Identify all Epross AVCON6 deployments and network exposure.
- Check Epross or trusted vendor guidance for patches or supported fixes.
- Restrict AVCON6 access to trusted administrative networks only.
- Block untrusted access to the login.action endpoint where feasible.
- Increase monitoring for suspicious AVCON6 web requests and process execution.
Validation and detection
- Confirm whether AVCON6 is deployed in production or management networks.
- Determine whether any AVCON6 instance is internet-accessible.
- Review web logs for unusual login.action redirect parameter activity.
- Review host logs for unexpected child processes from the AVCON6 service.
- Verify applied vendor updates or compensating network controls.

Unauthorized Error Injection Can Degrade Hardware Redundancy
Unauthorized Error Injection Can Degrade Hardware Redundancy represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
