Nginx UI: Server-Side Request Forgery (SSRF) via Cluster Proxy Middleware Allows Access to Internal Services

Nginx UI is a web user interface for the Nginx web server. In 2.3.4 and earlier, an authenticated user can perform Server-Side Request Forgery (SSRF) by creating a cluster node pointing to an arbitrary internal URL and then sending API requests with the X-Node-ID header. The Proxy middleware forwards these requests to the attacker-specified internal address, bypassing network segmentation and enabling access to services bound to localhost or internal networks.

nginx-ui: Unauthenticated First-Run Installer Allows Remote Initial Admin Claim

Nginx UI is a web user interface for the Nginx web server. From version 2.0.0 to before version 2.3.8, an unauthenticated network attacker can claim the initial administrator account on a fresh nginx-ui instance during the first-run setup window. The public /api/install endpoint is reachable without authentication, and the request-encryption flow only protects payload confidentiality in transit; it does not authenticate who is allowed to perform installation. A remote attacker who reaches the se…

nginx-ui: Authenticated settings disclosure exposes node.secret and enables trusted-node authentication abuse, backup exfiltration, and restore-based nginx-ui state rollback

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.8, an authenticated user can call GET /api/settings and retrieve sensitive configuration values, including node.secret. The same node.secret is accepted by AuthRequired() through the X-Node-Secret header (or node_secret query parameter), causing the request to be treated as authenticated via the trusted-node path and associated with the init user. This issue has been patched in version 2.3.8.

Nginx-UI vulnerable to Cross-Site WebSocket Hijacking (CSWSH) via missing origin validation on all WebSocket endpoints

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.5, all WebSocket endpoints in nginx-ui use a gorilla/websocket Upgrader with CheckOrigin unconditionally returning true, allowing Cross-Site WebSocket Hijacking (CSWSH). Combined with the fact that authentication tokens are stored in browser cookies (set via JavaScript without HttpOnly or explicit SameSite attributes), a malicious webpage can establish authenticated WebSocket connections to the nginx-ui instance when…

Nginx-UI: Disabled users retain full API access through previously issued bearer tokens

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, a user who was disabled by an administrator can use previously issued API tokens for up to the token lifetime. In practice, disabling a compromised account does not actually terminate that user’s access, so an attacker who already stole a JWT can continue reading and modifying protected resources after the account is marked disabled. Since tokens can be used to create new accounts, it is possible the disabled user…

nginx-ui Backup Restore Allows Tampering with Encrypted Backups

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, the nginx-ui backup restore mechanism allows attackers to tamper with encrypted backup archives and inject malicious configuration during restoration. This issue has been patched in version 2.3.4.

Nginx UI: Improper Path Validation Allows Recursive Deletion of the Nginx Configuration Directory

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, the nginx-ui configuration improperly handles URL-encoded traversal sequences. When specially crafted paths are supplied, the backend resolves them to the base Nginx configuration directory and executes the operation on the base directory (/etc/nginx). In particular, this allows an authenticated user to remove the entire /etc/nginx directory, resulting in a partial Denial of Service. This issue has been patched in…

Nginx UI: Race Condition Leads to Persistent Data Corruption and Service Collapse

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, the nginx-ui application is vulnerable to a Race Condition. Due to the complete absence of synchronization mechanisms (Mutex) and non-atomic file writes, concurrent requests lead to the severe corruption of the primary configuration file (app.ini). This vulnerability results in a persistent Denial of Service (DoS) and introduces a non-deterministic path for Remote Code Execution (RCE) through configuration cross-c…

Nginx UI: DoS via Negative Integer Input in Logrotate Interval

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, an input validation vulnerability in the logrotate configuration allows an authenticated user to cause a complete Denial of Service (DoS). By submitting a negative integer for the rotation interval, the backend enters an infinite loop or an invalid state, rendering the web interface unresponsive. This issue has been patched in version 2.3.4.

Nginx UI: Unauthenticated MCP Endpoint Allows Remote Nginx Takeover

Nginx UI is a web user interface for the Nginx web server. In versions 2.3.5 and prior, the nginx-ui MCP (Model Context Protocol) integration exposes two HTTP endpoints: /mcp and /mcp_message. While /mcp requires both IP whitelisting and authentication (AuthRequired() middleware), the /mcp_message endpoint only applies IP whitelisting - and the default IP whitelist is empty, which the middleware treats as "allow all". This means any network attacker can invoke all MCP tools without authenticatio…

Nginx UI: Unauthenticated Backup Download with Encryption Key Disclosure

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.3, the /api/backup endpoint is accessible without authentication and discloses the encryption keys required to decrypt the backup in the X-Backup-Security response header. This allows an unauthenticated attacker to download a full system backup containing sensitive data (user credentials, session tokens, SSL private keys, Nginx configurations) and decrypt it immediately. This issue has been patched in version 2.3.3.

Nginx-UI authenticated RCE through injecting into the application config via CRLF

Nginx-UI is a web interface to manage Nginx configurations. It is vulnerable to an authenticated arbitrary command execution via CRLF attack when changing the value of test_config_cmd or start_cmd. This vulnerability exists due to an incomplete fix for CVE-2024-22197 and CVE-2024-22198. This vulnerability has been patched in version 2.0.0.beta.12.

Nginx-UI arbitrary file write through the Import Certificate feature

Nginx-UI is a web interface to manage Nginx configurations. The Import Certificate feature allows arbitrary write into the system. The feature does not check if the provided user input is a certification/key and allows to write into arbitrary paths in the system. It's possible to leverage the vulnerability into a remote code execution overwriting the config file app.ini. Version 2.0.0.beta.12 fixed the issue.

Authenticated (user role) arbitrary command execution by modifying `start_cmd` setting (GHSL-2023-268)

Nginx-UI is a web interface to manage Nginx configurations. It is vulnerable to arbitrary command execution by abusing the configuration settings. The `Home > Preference` page exposes a list of system settings such as `Run Mode`, `Jwt Secret`, `Node Secret` and `Terminal Start Command`. While the UI doesn't allow users to modify the `Terminal Start Command` setting, it is possible to do so by sending a request to the API. This issue may lead to authenticated remote code execution, privilege esca…

Authenticated (user role) SQL injection in `OrderAndPaginate` (GHSL-2023-270)

Nginx-UI is an online statistics for Server Indicators Monitor CPU usage, memory usage, load average, and disk usage in real-time. This issue may lead to information disclosure. By using `DefaultQuery`, the `"desc"` and `"id"` values are used as default values if the query parameters are not set. Thus, the `order` and `sort_by` query parameter are user-controlled and are being appended to the `order` variable without any sanitization. This issue has been patched in version 2.0.0.beta.9.

Authenticated (user role) remote command execution by modifying `nginx` settings (GHSL-2023-269)

Nginx-ui is online statistics for Server Indicators Monitor CPU usage, memory usage, load average, and disk usage in real-time. The `Home > Preference` page exposes a small list of nginx settings such as `Nginx Access Log Path` and `Nginx Error Log Path`. However, the API also exposes `test_config_cmd`, `reload_cmd` and `restart_cmd`. While the UI doesn't allow users to modify any of these settings, it is possible to do so by sending a request to the API. This issue may lead to authenticated R…
