Publicly-known default superuser password permits remote unauthenticated admin login (PR:N/AC:L) yielding full control (C:H/I:H/A:H); limited only by whether the default was changed, a deployment factor.

Lifecycle Timeline
2DescriptionCVE.org
A vulnerability was identified in aiyiyi121 SxDevOps 1.0/1.1. This vulnerability affects the function ensure_default_superuser of the file rbac/services.py. The manipulation leads to hard-coded credentials. The attack is possible to be carried out remotely. The identifier of the patch is 2b4bf8585c3e731e7a8af30801ea46680bc783f9. It is recommended to apply a patch to fix this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
AnalysisAI
Hard-coded default superuser credentials in aiyiyi121 SxDevOps 1.0/1.1 let unauthenticated remote attackers log in to the management/API interface as a superuser, because the shipped password (Admin@123456, published in the project's own README) is generated by ensure_default_superuser in rbac/services.py and is never forced to be changed. The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N, VC/VI/VA:L) confirms no authentication or user interaction is required and that the attack is network-reachable; our own assessment rates the true impact higher (C/I/A:H) since a superuser session yields full control of managed hosts and tasks, limited only by whether the operator changed the default after initialization. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires that the SxDevOps deployment was initialized by ensure_default_superuser without overriding the default password - i.e., the operator did not set SXDEVOPS_ADMIN_INITIAL_PASSWORD/SXDEVOPS_DEMO_PASSWORD and left the shipped default Admin@123456 in place (behavior of versions 1.0/1.1 before commit 2b4bf858). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor scores this CVSS 4.0 6.9 (AV:N/AC:L/PR:N/UI:N/VC:L/VI:L/VA:L), but that low VC/VI/VA:L rating understates the real impact: the flaw is a hard-coded default superuser password (Admin@123456, documented in the project's own README) created by ensure_default_superuser in rbac/services.py. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the upstream fix: upgrade to the corrected SxDevOps release the vendor states it published, or cherry-pick/merge patch commit 2b4bf8585c3e731e7a8af30801ea46680bc783f9 (https://github.com/aiyiyi121/sxdevops/commit/2b4bf8585c3e731e7a8af30801ea46680bc783f9 , see also https://github.com/aiyiyi121/sxdevops/issues/16 ), which removes the embedded password and instead requires SXDEVOPS_ADMIN_INITIAL_PASSWORD (and optionally SXDEVOPS_DEMO_PASSWORD) to be set before initialization, otherwise generating a random one-time password that is printed once to the command output - note that this means an operator who relied on the old login must capture and store the new generated password during setup or the superuser becomes inaccessible. … Detailed patch versions, workarounds, and compensating controls in full report. |
