CVE-2025-8769
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 · uneditedTelenium Online Web Application is vulnerable due to a Perl script that is called to load the login page. Due to improper input validation, an attacker can inject arbitrary Perl code through a crafted HTTP request, leading to remote code execution on the server.
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 confidenceTelenium Online Web Application contains a command injection vulnerability in a Perl script used to load the login page. Due to improper input validation, attackers can inject arbitrary Perl code through crafted HTTP requests, achieving remote code execution on the server.

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 Web Application is installedSearch for Telenium-related files, directories, or services on the system. Look for web application directories containing Perl scripts, or check running web services for Telenium components.Affected if Telenium Online is present on the system
-
Locate the Perl login scriptSearch for Perl scripts in the Telenium web application directory, particularly those related to authentication or login functionality. Common paths may include /cgi-bin/, /scripts/, or the main application root.Affected if A Perl script handling the login page exists in the Telenium installation
-
Verify the login page is accessible via HTTPAttempt to access the login endpoint (such as /login.pl, /cgi-bin/login.pl, or similar) through an HTTP request to confirm the vulnerable script is exposed.Affected if The login Perl script is reachable over HTTP/HTTPS
-
Inspect input validation in the login scriptExamine the Perl login script source code for user-supplied parameter handling. Look for unvalidated inputs passed to system calls, exec, qx, or similar functions that could allow command injection.Affected if The script accepts user input without proper sanitization before executing system commands
-
Compare installed version to any available version informationCheck the Telenium installation for version files, headers, or application metadata that indicate the installed version. Compare against any vendor release notes or security advisories.Affected if The installed version matches known affected version ranges (if available) or no patch has been applied
The environment is affected if Telenium Online Web Application is installed and the login Perl script is accessible without having applied vendor patches that address the 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 dataImplement strict input validation and sanitization on all user-supplied parameters in the vulnerable Perl login script, or apply vendor-provided patches if available. Consider temporary mitigation by restricting access to the affected endpoint until the fix is deployed.
