- Hardcoded CNBlogs API Credential in Test Script## Vulnerability Details **File Location**: `tests/test_all.sh:4-6` **Vulnerability Type**: Hardcoded access token and account information **Risk Level**: High ### Vulnerable Code ```bash export CNBLOGS_BLOG_URL="https://rpc.cnblogs.com/metaweblog/sueyyyy" export CNBLOGS_USERNAME="suyang320" export CNBLOGS_TOKEN="03989364193E50C002FD667C5F016FC00423F010502BC4958DC3EA953527806A" ``` ### Technical Analysis The test script contains a plaintext CNBlogs MetaWeblog access token alongside the corresponding username and API endpoint. A credential committed to a project must be considered compromised because it can be recovered from distributed copies, archives, logs, or version-control history even if it is removed in a later revision. The project's scripts pass this token to authenticated XML-RPC methods that can retrieve, create, edit, publish, and delete posts. If the token remains valid, possession of the project is potentially sufficient to perform operations under the affected CNBlogs account. ### Attack Path 1. An attacker obtains a copy of the project or its version-control history. 2. The attacker reads `tests/test_all.sh` and extracts the API endpoint, username, and token. 3. The attacker submits the credentials to the CNBlogs MetaWeblog endpoint. 4. The attacker invokes supported methods such as `getRecentPosts`, `getPost`, `newPost`, `editPost`, or `deletePost`. 5. Depending on the token's server-side privileges and validity, the attacker reads private drafts or modifies, publishes, and deletes blog content. ### Impact Assessment The exposed token may grant authenticated access to the associated CNBlogs account's MetaWeblog functionality. Potential impact includes disclosure of posts and drafts, unauthorized content creation, modification or publication of existing content, and deletion of posts. The scope is limited by the permissions assigned to the exposed token and whether CNBlogs has already revoked it.
- Remediation
- ## Remediation Suggestions 1. Immediately revoke the exposed CNBlogs token and generate a replacement. 2. Remove the credential from the current tree and purge it from version-control history using an appropriate history-rewriting tool. 3. Require test credentials to be supplied through protected environment variables or a dedicated secret manager. 4. Commit only a placeholder configuration, such as `CNBLOGS_TOKEN="your-token"`. 5. Restrict the replacement token to the minimum permissions supported by CNBlogs. 6. Add automated secret scanning to local hooks and CI pipelines. 7. Review account activity for unauthorized API operations performed with the exposed token.
