CVE-2026-68503: LazyOwn: Default C2 Operator Credentials Enable Administrative Access to C2 Dashboard

What it is

LazyOwn RedTeam/APT Framework is an AI-powered C2 and red-team operations framework. Prior to 0.2.154, LazyOwn ships default C2 credentials LazyOwn and LazyOwn in payload.json and core/payload_schema.py and passes them unchanged to lazyc2.py HTTP Basic authentication, allowing any network-reachable attacker who knows the defaults to authenticate to the C2 dashboard with operator-level access. This issue is fixed in 0.2.154.

Description quoted from the CVE record (assigned by GitHub_M, published 2026-07-30).

LazyOwn - Default Credentials

LazyOwn RedTeam/APT Framework before 0.2.154 ships default C2 credentials (LazyOwn / LazyOwn) in payload.json and passes them unchanged to the lazyc2.py HTTP Basic authentication gate. Any network-reachable unauthenticated attacker who knows the defaults can authenticate to the C2 dashboard with operator-level access. The template sends an unauthenticated request (expecting the Basic-auth rejection) and then the same request with the default credentials, confirming the gate is defeated.

Name and description quoted from the template, written by VEDAS.

The template sends 2 requests (GET /api/data, GET /api/data); it decides using dsl matchers. Severity in the template: critical. Marked as not yet verified against a live vulnerable target.
