NVD · unedited
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.
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 analysis · moderate confidence
LazyOwn RedTeam/APT Framework contains hardcoded default credentials (username: LazyOwn, password: LazyOwn) embedded in payload.json and core/payload_schema.py. These credentials are used for HTTP Basic authentication to the C2 dashboard and are transmitted unchanged, allowing any network-adjacent attacker to gain operator-level access.
MitigationImmediately upgrade to version 0.2.154 or later and change default credentials to strong, unique values. Restrict network access to the C2 dashboard and audit for any unauthorized access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checks
Work through these to decide whether this CVE applies to you.
Locate LazyOwn installation and determine version
Search for the LazyOwn C2 framework installation directory (commonly in /opt, /usr/share, or the user's home directory). Look for a version file or check the main lazyc2.py script for a version string. Compare the installed version to 0.2.154.
Affected if The installed version is earlier than 0.2.154 or the version cannot be determined.
Inspect payload.json for hardcoded credentials
Open the payload.json file in the LazyOwn installation directory and search for the strings 'LazyOwn' appearing as both username and password in any authentication-related configuration sections.
Affected if The default credentials (username: LazyOwn, password: LazyOwn) are present in payload.json.
Inspect core/payload_schema.py for hardcoded credentials
Open the core/payload_schema.py file in the LazyOwn installation directory and search for hardcoded strings 'LazyOwn' used as default values for authentication parameters.
Affected if The default credentials (username: LazyOwn, password: LazyOwn) are hardcoded in core/payload_schema.py.
Verify HTTP Basic authentication is configured for the C2 dashboard
Check the LazyOwn configuration files (such as config.py, settings.json, or similar) for settings related to HTTP Basic authentication pointing to the lazyc2.py dashboard endpoint.
Affected if HTTP Basic authentication is enabled and configured to use the default credentials.
The environment is affected if LazyOwn version is prior to 0.2.154 AND the hardcoded default credentials (LazyOwn/LazyOwn) are found in payload.json or core/payload_schema.py AND HTTP Basic authentication is in use for the C2 dashboard.

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.
Immediately upgrade to version 0.2.154 or later and change default credentials to strong, unique values. Restrict network access to the C2 dashboard and audit for any unauthorized access.
Recommended fixHigh confidence
0.2.154
Upgrade LazyOwn to version 0.2.154 or later
After upgrading, change the default C2 credentials from LazyOwn/LazyOwn to a strong, unique password
Verify that the HTTP Basic authentication on lazyc2.py now uses the new credentials

CVE-2026-68503 documents hardcoded credentials (LazyOwn/LazyOwn) in the LazyOwn C2 framework, present in release version 0.2.153 and patched in 0.2.154. What makes this worth your attention isn't the CVSS 9.8 score — it's the pattern: the same credentials appeared across three separate artifacts (payload.json, core/payload_schema.py, and lazyc2.py). That's not a single forgotten line; that's a scaffold that got copied into production.
The real failure here is design-level, not code-level. The tool shipped credentials in plaintext across release artifacts, making it trivial to deploy and trivial to skip the hardening step. If you're using this framework or any similar C2 tool, verify you're on 0.2.154 or later. More importantly, check whether any deployed instances in your environment are still running the vulnerable version — red-team operators frequently prioritize operational continuity over updates, meaning known-vulnerable versions can persist in production far longer than they should.
The secondary risk is the pivot potential. Compromising a C2 framework doesn't just give you one server — it gives you everything that server was positioned to reach. The implants, the campaign data, the operator's access. That's the asymmetry this CVE creates: even a single exposed instance during the vulnerable window could have handed an attacker not just a box, but a capability.
If you maintain similar tooling, the fix isn't just removing strings — it's implementing fail-closed behavior where the tool refuses to activate network listeners until credentials are explicitly set in configuration. A prompt during setup is easy to skip; making the dashboard unreachable until credentials are configured forces the issue. That's the design change that prevents this pattern from recurring in the next feature branch.
