Security readout for executives and security teams
Plain-English summary
This issue affects V-SOL GPON/EPON OLT web management software. A malicious link can abuse a redirect parameter to send an authenticated user to an attacker-chosen site. This is most concerning for telecom or ISP operations where OLT administration portals are reachable by operators.
Executive priority
Prioritize if your organization operates V-SOL OLT infrastructure or exposes management portals beyond trusted networks. Treat as urgent for telecom operations because public details exist and administrator redirection can enable credential theft. If the product is not present, no direct action is needed.
Technical view
CVE-2019-25282 is a CWE-601 open redirect in bindProfile.html. The vulnerable logic improperly validates the parent GET parameter, allowing arbitrary redirect destinations. Sources list multiple V-SOL GPON/EPON OLT Platform versions including V2.03.62R_IPv6 through older V1.x releases. Public exploit/advisory entries exist, but no KEV listing is provided.
Likely exposure
Exposure is likely where listed V-SOL GPON/EPON OLT Platform versions are deployed and the web management interface is reachable to administrators. Internet-facing or broadly accessible management portals increase business risk. The sources do not provide asset prevalence or vendor patch status.
Exploitation context
The bundle includes public exploit database references, so defenders should assume technical details are public. The provided sources do not show CISA KEV status or confirmed active exploitation. The described impact is redirection of logged-in users, commonly useful for phishing or trust abuse.
Researcher notes
The CVSS score in the bundle is 9.8, but the described weakness is an open redirect, so impact depends heavily on management-interface exposure and administrator interaction. No source in the bundle names a patch. The CVE identifier is 2019, while the provided CVE publication date is 2026.
Mitigation direction
- Check V-SOL guidance for fixed firmware or official remediation.
- Restrict OLT management access to trusted networks or VPN.
- Remove direct internet exposure for administration interfaces.
- Train administrators to avoid unsolicited management-console links.
- Monitor for redirects using external parent parameter values.
Validation and detection
- Inventory V-SOL GPON/EPON OLT Platform versions in use.
- Confirm whether listed affected versions are present.
- Identify all reachable web management interfaces.
- Review logs for bindProfile.html requests with unusual parent values.
- Validate remediation against vendor guidance when available.
