Title
[NotCVE-2026-0012] EmpManageX Hardcoded Administrative Credentials in Login API Allow Full Access to Employee Records
Summary
---------------------------------------------------------------------------- NotCVE Advisory — NotCVE-2026-0012 ---------------------------------------------------------------------------- [-] Summary: kamalpanse18 EmpManageX, a Flask-based employee management application, ships hard-coded administrative credentials in its authentication logic. The username admin and the plaintext password admin123 are module-level constants in app.py, compared directly against the values submitted to the /api/login handler. An attacker who can reach the listener authenticates as the sole administrator and obtains full read and write control of every employee record. The credentials are not a guessable secret: the project's own README.md and QUICK_START.md state them openly. As shipped the server binds to 127.0.0.1 only, so the default exposure is local; a deployer who binds an external interface makes the same defect remotely reachable. CVSS:3.1 7.7 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). [-] Affected: kamalpanse18 EmpManageX, all versions (app.py). The repository has a single commit, f4de83b, dated 2025-12-31, and no tagged releases. No fixed version is currently verified. [-] Technical Description: ADMIN_USERNAME and ADMIN_PASSWORD are assigned at lines 17-18 of app.py and compared directly against the submitted values in the /api/login handler. The credential pair is a source-level constant with no configuration mechanism behind it: app.py contains no use of os.environ or os.getenv, no configuration file, no first-run setup step and no password-change endpoint. The only supported way to alter the administrator password is to edit the source and restart the process, and that change is lost whenever the deployment is refreshed from the upstream repository. The same value is therefore present in every unmodified deployment, and because README.md and QUICK_START.md state it openly it is a published constant rather than a guessable secret. A successful call to /api/login sets session['logged_in'], which is the only condition tested by the login_required decorator. No further authorisation check is performed, so the caller obtains the entire protected surface: POST /api/employee (create), GET /api/employees and GET /api/employee/<int:emp_id> (read all stored employee data), PUT /api/employee/<int:emp_id> (modify) and DELETE /api/employee/<int:emp_id> (delete). On a match the handler sets session['user_id'], session['username'] and session['logged_in'] and returns a signed session cookie marked permanent with a 24-hour lifetime, which the caller can replay against the protected endpoints. The entry point is app.run(debug=True, port=5000), which passes no host argument and therefore binds the Werkzeug development server to 127.0.0.1 only; README.md, SETUP_GUIDE.md and QUICK_START.md all direct the user to http://127.0.0.1:5000. In the configuration as shipped the endpoint is reachable only from the local host, which is what the CVSS vector above reflects. A deployer who binds 0.0.0.0 or places the application behind a reverse proxy makes the same defect remotely reachable. SETUP_GUIDE.md carries a "Security Recommendations for Production" section suggesting that the credentials be read from environment variables, but that guidance is not implemented in the shipped app.py, and the example it gives retains admin/admin123 as the fallback default. The step-by-step attack path and the full write-up are published at the advisory URL below.

Silent;Call — Pre-Authentication Remote Root in Cisco CUCM 15.x (SKYLINE-2026-001/002/003)
Summary
## Advisory Information - Advisory IDs: SKYLINE-2026-001, SKYLINE-2026-002, SKYLINE-2026-003 - Title: Pre-Authentication Remote Root via Tomcat Manager Header Injection + Hardcoded Credentials - CVSSv3.1: 10.0 (Critical) — AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H - CWE: CWE-798, CWE-644, CWE-269 - Product: Cisco Unified Communications Manager 15.0.1.12900-234 - Vendor: Cisco Systems, Inc. - Public Disclosure: 2026-08-04 - Researcher: 0xReadingSteiner (0xReadingSteiner () proton me) ## Summary A pre-authentication remote code execution chain in Cisco CUCM 15.x allows an unauthenticated network attacker to achieve root-level access in three HTTP requests. The chain exploits: 1. RemoteIpValve misconfiguration — accepts X-Forwarded-For from any source without internalProxies restriction, allowing IP spoofing as 127.0.0.1 2. Hardcoded Tomcat Manager credentials — identical on every CUCM 15.x installation (username: 1mJdd4WKi+ / password: 1ge1AVWsx~), not configurable by administrators 3. Unrestricted sudo for the tomcat user — passwordless gdb with an attacker-controlled command file in /tmp, plus three additional independent root escalation paths (systemctl, PYTHONPATH, LD_PRELOAD) ## Impact Root access to CUCM grants: interception of all voice communications via SRTP key extraction, silent activation of built-in CALEA-compliant lawful intercept wiretapping, access to all voicemail, complete CDR exfiltration, call routing manipulation, E911 disruption, and lateral movement into the voice VLAN. CUCM is deployed in Fortune 500 companies, US federal agencies, the Department of Defense, hospitals, financial institutions, law enforcement, and telecommunications providers worldwide. ## Quick Test curl -sk -H "X-Forwarded-For: 127.0.0.1" \ -u '1mJdd4WKi+:1ge1AVWsx~' \ "https://TARGET:443/manager/text/list"; If the response begins with "OK - Listed applications for virtual host [localhost]" — the system is vulnerable. ## Vendor Coordination - 17 CUCM submissions to ZDI — unprocessed - SSD paused CUCM acquisitions (Cisco won't fix existing reports) - Cisco PSIRT contacted 2026-08-04 — no response - MITRE CVE IDs requested (CNA of Last Resort) — pending This is advisory 1 of 55 identified vulnerabilities in CUCM 15.x. ## References Full advisory: https://github.com/0xReadingSteiner/Silent-Call PoC script: https://github.com/0xReadingSteiner/Silent-Call/blob/main/poc.sh Master index: https://github.com/0xReadingSteiner/cisco-security-research ## Disclosure Statement This research was conducted independently on commercially available software in a private laboratory. No proprietary source code, internal tools, or confidential information was used. Coordination was attempted through three independent channels before publication. Additional findings will be published on a rolling basis. 0xReadingSteiner 0xReadingSteiner@proton.mePGP: D5E22255F645A8B935056C278C0958C5D533080A Sent with [Proton Mail](https://proton.me/mail/home) secure email. _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: https://seclists.org/fulldisclosure/

CVE-2025-71317 (GCVE-0-2025-71317)

Vulnerability from cvelistv5 – Published: 2026-06-05 17:49 – Updated: 2026-06-05 19:35

Title
NetMan 204 Hard-coded Backdoor Credentials
Summary
NetMan 204 contains a hard-coded backdoor account with the username and password 'eurek' that grants administrative access. A remote, unauthenticated attacker can authenticate through the cgi-bin/login.cgi endpoint (for example /cgi-bin/login.cgi?username=eurek&password=eurek, which due to lax parameter validation can be shortened to /cgi-bin/login.cgi?username=eurek%20eurek) to obtain administrator privileges, allowing them to alter device configuration, enable the telnet/SSH services, and reset local user credentials.

Title
Ruckus vRIoT IoT Controller < 3.0.0.0 Hardcoded SSH Credentials RCE
Summary
The Ruckus vRIoT IoT Controller firmware versions prior to 3.0.0.0 (GA) contain hardcoded credentials for an operating system user account within an initialization script. The SSH service is network-accessible without IP-based restrictions. Although the configuration disables SCP and pseudo-TTY allocation, an attacker can authenticate using the hardcoded credentials and establish SSH local port forwarding to access the Docker socket. By mounting the host filesystem via Docker, an attacker can escape the container and execute arbitrary OS commands as root on the underlying vRIoT controller, resulting in complete system compromise.

Title
Ruckus vRIoT IoT Controller < 3.0.0.0 Hardcoded Tokens RCE
Summary
The Ruckus vRIoT IoT Controller firmware versions prior to 3.0.0.0 (GA) expose a command execution service on TCP port 2004 running with root privileges. Authentication to this service relies on a hardcoded Time-based One-Time Password (TOTP) secret and an embedded static token. An attacker who extracts these credentials from the appliance or a compromised device can generate valid authentication tokens and execute arbitrary OS commands with root privileges, resulting in complete system compromise.

CVE-2025-68926 (GCVE-0-2025-68926)

Title
RustFS has a gRPC Hardcoded Token Authentication Bypass
Summary
RustFS is a distributed object storage system built in Rust. In versions prior to 1.0.0-alpha.78, RustFS implements gRPC authentication using a hardcoded static token `"rustfs rpc"` that is publicly exposed in the source code repository, hardcoded on both client and server sides, non-configurable with no mechanism for token rotation, and universally valid across all RustFS deployments. Any attacker with network access to the gRPC port can authenticate using this publicly known token and execute privileged operations including data destruction, policy manipulation, and cluster configuration changes. Version 1.0.0-alpha.78 contains a fix for the issue.

CVE-2025-66454 (GCVE-0-2025-66454)

Vulnerability from cvelistv5 – Published: 2025-12-02 18:23 – Updated: 2025-12-02 19:28

Title
Arcade MCP Default Hardcoded Worker Secret Allows Full Unauthorized Access to All HTTP MCP Worker Endpoints
Summary
Arcade MCP allows you to to create, deploy, and share MCP Servers. Prior to 1.5.4, the arcade-mcp HTTP server uses a hardcoded default worker secret ("dev") that is never validated or overridden during normal server startup. As a result, any unauthenticated attacker who knows this default key can forge valid JWTs and fully bypass the FastAPI authentication layer. This grants remote access to all worker endpoints—including tool enumeration and tool invocation—without credentials. This vulnerability is fixed in 1.5.4.

Mitigation
Architecture and Design
  • For outbound authentication: store passwords, keys, and other credentials outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible [REF-7].
  • In Windows environments, the Encrypted File System (EFS) may provide some protection.
Mitigation
Architecture and Design

For inbound authentication: Rather than hard-code a default username and password, key, or other authentication credentials for first time logins, utilize a "first login" mode that requires the user to enter a unique strong password or key.

Mitigation
Architecture and Design

If the product must contain hard-coded credentials or they cannot be removed, perform access control checks and limit which entities can access the feature that requires the hard-coded credentials. For example, a feature might only be enabled through the system console instead of through a network connection.

Mitigation
Architecture and Design
  • For inbound authentication using passwords: apply strong one-way hashes to passwords and store those hashes in a configuration file or database with appropriate access control. That way, theft of the file/database still requires the attacker to try to crack the password. When handling an incoming password during authentication, take the hash of the password and compare it to the saved hash.
  • Use randomly assigned salts for each separate hash that is generated. This increases the amount of computation that an attacker needs to conduct a brute-force attack, possibly limiting the effectiveness of the rainbow table method.
Mitigation
Architecture and Design
  • For front-end to back-end connections: Three solutions are possible, although none are complete.
  • The first suggestion involves the use of generated passwords or keys that are changed automatically and must be entered at given time intervals by a system administrator. These passwords will be held in memory and only be valid for the time intervals.
  • Next, the passwords or keys should be limited at the back end to only performing actions valid for the front end, as opposed to having full access.
  • Finally, the messages sent should be tagged and checksummed with time sensitive values so as to prevent replay-style attacks.
CAPEC-191: Read Sensitive Constants Within an Executable

An adversary engages in activities to discover any sensitive constants present within the compiled code of an executable. These constants may include literal ASCII strings within the file itself, or possibly strings hard-coded into particular routines that can be revealed by code refactoring methods including static and dynamic analysis.

CAPEC-70: Try Common or Default Usernames and Passwords

An adversary may try certain common or default usernames and passwords to gain access into the system and perform unauthorized actions. An adversary may try an intelligent brute force using empty passwords, known vendor default credentials, as well as a dictionary of common usernames and passwords. Many vendor products come preconfigured with default (and thus well-known) usernames and passwords that should be deleted prior to usage in a production environment. It is a common mistake to forget to remove these default login credentials. Another problem is that users would pick very simple (common) passwords (e.g. "secret" or "password") that make it easier for the attacker to gain access to the system compared to using a brute force attack or even a dictionary attack using a full dictionary.
