CVE-2025-10659
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Telenium Online Web Application is vulnerable due to a PHP endpoint accessible to unauthenticated network users that improperly handles user-supplied input. This vulnerability occurs due to the insecure termination of a regular expression check within the endpoint. Because the input is not correctly validated or sanitized, an unauthenticated attacker can inject arbitrary operating system commands through a crafted HTTP request, leading to remote code execution on the server in the context of the web application service account.
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 · high confidenceThe Telenium Online Web Application contains a PHP endpoint accessible to unauthenticated users that fails to properly validate or sanitize user input. The vulnerability stems from an insecure termination of a regular expression check within the endpoint, allowing attackers to inject arbitrary operating system commands through crafted HTTP requests and achieve remote code execution.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Telenium Online is installedSearch the web server document root for files containing 'Telenium' or check web application directories for Telenium-specific PHP filesAffected if The application is present on the server
-
Identify the PHP endpoint with regex handlingLocate PHP files in the Telenium web directory that process HTTP request parameters and contain regular expression operations (preg_match, preg_replace, etc.)Affected if A PHP endpoint processing user input with regex is found
-
Check if endpoint allows unauthenticated accessVerify the PHP endpoint does not require authentication tokens, sessions, or login checks before processing requestsAffected if The endpoint is accessible without authentication credentials
-
Determine installed versionCheck version file, composer.json, or header/meta information within the Telenium installation directoryAffected if The installed version falls within any vulnerable range or cannot be determined (treat as potentially affected)
-
Verify command injection is possibleSend a crafted HTTP request to the endpoint with injected shell metacharacters (e.g., |, ;, &&) in input parameters used within regex operationsAffected if The application executes injected OS commands from unauthenticated requests
If Telenium Online is present with an unauthenticated-accessible PHP endpoint that processes user input through regex operations, the environment is likely affected and should be tested for command injection vulnerability.

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.
From vendor dataRestrict network access to the vulnerable PHP endpoint and implement proper input validation/sanitization to prevent command injection. Apply vendor patch when available.
