CVE-2015-0554
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe ADB (formerly Pirelli Broadband Solutions) P.DGA4001N router with firmware PDG_TEF_SP_4.06L.6 does not properly restrict access to the web interface, which allows remote attackers to obtain sensitive information or cause a denial of service (device restart) as demonstrated by a direct request to (1) wlsecurity.html or (2) resetrouter.html.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisA legacy NVD category covering weaknesses where permissions or privileges are assigned, checked, or dropped incorrectly, so an action ends up running with more access than it should. It is an umbrella label from older records, not a single flaw. The remedy depends on the specific case, but the throughline is least privilege with explicit, checked transitions wherever privilege changes.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped- This is a legacy ISP-provided router (ADB/Pirelli) that reached end-of-life with no manufacturer support.
- Replace the router with a currently-supported device from a vendor that provides regular security updates.
- If replacement is not immediately possible, implement network isolation: place the router in a restricted VLAN away from sensitive systems.
- Block external/internet access to the router's web interface (ports 80/443) at the upstream firewall.
- Monitor for unauthorized access attempts to wlsecurity.html and resetrouter.html endpoints.
- Contact your ISP to request a modern replacement router or inquire about firmware update availability.
Generated from the published advisory — verify against the referenced sources before acting.
There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
Free. We build fixes in the order the community asks for them — and we’ll tell you the moment this one lands.
We develop and verify an original fix where the vendor hasn’t, from $1,950. Deployed to your staging first — never straight to production.

The advisory tells you what broke. It rarely tells you what actually worked. If you’ve dealt with this one, that detail is what the next engineer is searching for.
- The version that genuinely resolved it — not the one the vendor claimed
- A config change or rule that shut the vector down
- A gotcha in the upgrade path that cost you an afternoon
