CVE-2025-2473 is a high severity SQL injection (CVSS 7.3) in PHPGurukul Company Visitor Management System 2.0, in the file /index.php through the username argument. The record lists no fixed version. Until the vendor ships one, limit who can reach the app, review logs for abuse, and move the query to parameterized statements.
What's affected
The NVD record names PHPGurukul Company Visitor Management System 2.0. The weak spot is the file /index.php of the Sign In component, where the username value reaches a database query without safe handling. The description says the exploit has been disclosed to the public. The record is not on the CISA Known Exploited Vulnerabilities list, so there is no listed evidence of attacks in the wild.
The weaknesses are classed as CWE-74 (injection) and CWE-89 (SQL injection). The score is 7.3 (HIGH). The vector, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L, reads as reachable over the network, low attack complexity, no privileges required and no user interaction. Impact is limited on confidentiality, limited on integrity and limited on availability. The record was published on 2025-03-18.
The record lists no fixed version, and none of its references is a vendor advisory with a patch, so I cannot name one. Check the PHPGurukul site for a newer release before assuming you must stay on this build. Treat any copy at the listed version as exposed until you know otherwise.
How to check if you're exposed
Company Visitor Management System is a self-hosted web application, not a package from a registry, so no single command lists it across your estate. Work through these checks.
- Find every copy. Search web roots and repositories for the file name.
find /var/www -name "index.php" 2>/dev/null
- Confirm the product and version from its documentation or footer and compare it with 2.0.
- Check whether the app is reachable from the internet or only from an internal network.
- Search web server access logs for requests to the file that carry quote characters or SQL keywords.
grep "index.php" /var/log/apache2/access.log | grep -iE "union|select|sleep|%27"
A hit is a lead, not proof, because bots produce similar noise. A clean result is not proof of safety either, since logs rotate and a POST body is not logged by default.
What to do now
- Find every copy of Company Visitor Management System 2.0 in your environment, including test and demo installs that people forgot.
- If nobody needs it, take it offline. An unused install is only risk.
- Restrict access with a VPN, an IP allowlist or web server authentication in front of the affected path while you wait for a vendor fix.
- Add a web application firewall rule for SQL keywords in
usernameas a stopgap. It buys time and does not fix the code. - If you maintain the code, replace string built queries with prepared statements using mysqli or PDO, and run the app with a database account that has only the rights it needs.
- Watch the PHPGurukul site for a release, then upgrade and re-test the affected page.
Why it matters
SQL injection happens when text typed by a user becomes part of the query itself. The database cannot tell which part was meant as data and which part was meant as an instruction, so crafted input can change what the query does. This is a well understood class of bug, listed here as CWE-89 and CWE-74, and the fix is equally well understood: send the value as a bound parameter instead of pasting it into the string.
Small PHP applications like this one are often written for learning or for quick internal use, then end up on a public server. A company visitor system keeps visitor identities, host names and admin accounts. Because the record shows no privileges are needed, a single exposed copy is enough to matter. If you track many applications, the free in-browser dependency scan at gold.safeguard.sh/scan can show which of your components have known CVEs, and the Gold directory lists each one with its fix status.
Quick check
Is a fix available for CVE-2025-2473?
The record lists no fixed version and no vendor advisory, so none is confirmed here. Check the PHPGurukul site, and until you find one, restrict access and review logs.
Does this affect me if the app is only on an internal network?
Exposure is lower, but not zero. The vector shows the attack runs over the network with no privileges, so anyone who can reach the page, including someone already inside your network, could try it. Limit access to those who need it.
