Security readout for executives and security teams
Plain-English summary
This issue affects Devolo dLAN 500 AV Wireless+ firmware 3.1.0-1. A malicious website could cause a logged-in administrator’s browser to make unauthorized device configuration changes. Business risk is mainly unauthorized network device changes, not data theft or full takeover based on the provided sources.
Executive priority
Treat as a moderate-priority network device hardening issue. Prioritize if these devices manage important network segments, expose administration broadly, or are used by non-technical staff. The main urgency is reducing unauthorized configuration-change risk and verifying vendor update options.
Technical view
CVE-2019-25250 is a CWE-352 cross-site request forgery in Devolo dLAN 500 AV Wireless+ 3.1.0-1. The disclosure describes predictable URL actions and missing request validation for administrative functions. Public exploit material is referenced, but the sources do not establish active exploitation. The supplied CVSS is 5.3, though the CSRF description implies user/browser interaction.
Likely exposure
Exposure is most relevant where the device administration interface is reachable by users browsing the web while authenticated. Internet-exposed or broadly reachable management interfaces increase risk. Organizations without this Devolo model or firmware version are not indicated as affected by the provided sources.
Exploitation context
An attacker would need to lure or cause an authenticated administrator’s browser to visit attacker-controlled content. The cited ExploitDB entry indicates public exploit information exists, but there is no KEV listing and no cited evidence of active exploitation.
Researcher notes
Use the CVE record, Zero Science Lab advisory, and ExploitDB reference as primary public sources. Do not assume other Devolo models or firmware are affected beyond the provided bundle. The provided CVSS vector states UI:N, but the CSRF scenario described requires an authenticated user’s browser context.
Mitigation direction
- Identify any Devolo dLAN 500 AV Wireless+ devices running firmware 3.1.0-1.
- Restrict access to the device administration interface to trusted management networks.
- Avoid browsing untrusted sites while logged into the device administration interface.
- Log out of the device interface after administrative work.
- Check Devolo guidance for firmware updates or vendor-recommended mitigations.
Validation and detection
- Inventory Devolo powerline devices and record model and firmware version.
- Confirm whether administrative interfaces are reachable from user workstations or the internet.
- Review device configuration for unexpected administrative changes.
- Check vendor resources for available firmware or security advisories.
- Document compensating controls if no vendor fix is available.

Cross-Site Request Forgery (CSRF)
Cross-Site Request Forgery (CSRF) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
