Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.19% for the current model date.

Compensating controls

  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs WODESYS WD-R608U and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 30 daysRemediation target: Within 180 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

01

What, why and how

In WODESYS WD-R608U router (also known as WDR122B V2.0 and WDR28) an unauthorised user can view configuration files by directly referencing the resource in question. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version WDR28081123OV1.01 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

What

In WODESYS WD-R608U router (also known as WDR122B V2.0 and WDR28) an unauthorised user can view configuration files by directly referencing the resource in question. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version WDR28081123OV1.01 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Why

The web application does not adequately enforce appropriate authorization on all restricted URLs, scripts, or files.

How

An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
an adjacent network → Direct Request ('Forced Browsing') → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Adjacent
Privileges required
None: unauthenticated exploitation is possible
User interaction
None
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Not a CVSS 4.0 base metric
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-425 ↗

CWE-425: Direct Request ('Forced Browsing'). The web application does not adequately enforce appropriate authorization on all restricted URLs, scripts, or files.

CERT Polska otrzymał zgłoszenie o podatnościach w oprogramowaniu routera WODESYS WD-R608U i koordynował proces ujawniania informacji. Podatność CVE-2025-65007 : W routerze WD-R608U (znanym również pod nazwą WDR122B V2.0 i WDR28) z powodu braku uwierzytelniania w module zmiany konfiguracji w endpoincie 'adm.cgi', nieuwierzytelniony atakujący może wykonać polecenia, w tym tworzenie kopii zapasowych, restart urządzenia oraz przywracanie urządzenia do ustawień fabrycznych. Podatność CVE-2025-65008 : W routerze WD-R608U (znanym również pod nazwą WDR122B V2.0 i WDR28) z powodu braku walidacji parametru 'langGet' w endpoincie 'adm.cgi', atakujący może wykonywać polecenia powłoki systemowej. Podatność CVE-2025-65009 : W routerze WD-R608U (znanym również pod nazwą WDR122B V2.0 i WDR28) hasło administratora jest przechowywane w pliku konfiguracyjnym w postaci zwykłego tekstu i może zostać uzyskane przez nieautoryzowanego użytkownika poprzez bezpośrednie odwołania do odpowiedniego zasobu. Podatność CVE-2025-65010 : W routerze WD-R608U (znanym również pod nazwą WDR122B V2.0 i WDR28) atakujący może zmienić hasło do panelu administratora bez autoryzacji. Podatność może być również wykorzystana po zakończeniu wstępnej konfiguracji. Podatność CVE-2025-65011 : W routerze WD-R608U (znanym również pod nazwą WDR122B V2.0 i WDR28) nieautoryzowany użytkownik może przeglądać pliki konfiguracyjne poprzez bezpośrednie odwołanie do odpowiedniego zasobu. Producent został wcześnie poinformowany o tej podatności, jednak nie udzielił informacji na temat szczegółów podatności ani zakresu wersji podatnych na atak. Przetestowano i potwierdzono podatność jedynie w wersji WDR28081123OV1.01 — inne wersje nie były testowane i również mogą być podatne.
