CVE-2025-4514 is a medium SQL injection flaw (CVSS 6.3) in mayicms up to 5.8E. The file /javascript.php builds a database query from the Value argument without handling it safely, and the attack works over the network and needs only a low privilege account. The record lists no fixed version, so restrict access and fix the query code.
What's affected
Per the CVE record, mayicms versions up to 5.8E from Zhengzhou Jiuhua Electronic Technology are affected. The weakness sits in the file /javascript.php. The record names the Value argument.
The record lists no patched release, and no vendor advisory is referenced. Do not assume an update exists. Check the vendor's download page for a newer build, and treat versions up to 5.8E as vulnerable until you have evidence otherwise.
The record also says the exploit has been disclosed to the public. It does not say the bug is being exploited in the wild, and the CISA Known Exploited Vulnerabilities list does not include it. Public disclosure still matters, because it lowers the effort an attacker needs.
How to check if you're exposed
Start with inventory. Find out whether this application runs anywhere in your estate, including test servers and forgotten hosting accounts. On a Linux web host, a search for the vulnerable file name is a quick first pass:
find /var/www -name "javascript.php" 2>/dev/null
If the file exists, open it and look at how the query is built. Values taken straight from $_GET or $_POST and joined into an SQL string are the pattern to look for:
grep -n "SELECT\|INSERT\|UPDATE\|DELETE" javascript.php
Next, review your web server logs for requests to this path, especially ones with unusual characters in the parameter. A count of requests per client address can show scanning:
grep "/javascript.php" /var/log/nginx/access.log | awk '{print $1}' | sort | uniq -c | sort -rn | head
Adjust the log path for your server. Heavy traffic from one address to a rarely used page is worth a closer look. If you cannot tell, a dynamic scan of the running application will show whether the page accepts the input unsafely.
What to do now
- Find every copy of mayicms you run, and confirm the version.
- If the application does not need to be public, take it off the internet or limit it to a VPN or an allow list.
- Check the vendor site for a newer release and read its notes. If none is listed, plan to fix the code yourself or retire the app.
- Replace string built queries in
javascript.phpwith prepared statements and bound parameters, and validate that identifiers are whole numbers where the field is an ID. - Make sure the database account the application uses has only the rights it needs, and never use an administrator account.
- Review logs and the database for unexpected reads or changes since the application went live.
- Back up the database before any change, and test the fix on a copy.
Why it matters
The record maps this issue to CWE-74 and CWE-89. In plain terms, user input is mixed into a database command and the database cannot tell data from instructions. Depending on the account the application uses, that can expose records, change them or delete them. The CVSS vector rates the impact as low across confidentiality, integrity and availability, which is why the score is 6.3 and not higher.
A SQL injection bug like this is rarely one flaw in one place. Small PHP applications of this kind tend to build queries the same way across many files, so a single report is often a hint about the rest.
Dependency scanners will not catch this kind of flaw, because it lives in the application's own code and not in a library. A static code scan or a dynamic scan of the running app is the right tool. Safeguard's free in-browser dependency scan at gold.safeguard.sh/scan covers the libraries you ship, and the Gold directory lets you look up other CVEs by product.
Quick check
Is CVE-2025-4514 being exploited in the wild?
The CVE record says an exploit has been disclosed publicly, but it does not report exploitation in the wild, and the record's CISA KEV flag is false. Treat the risk as real and act on it.
Is there a patched version of mayicms?
The record does not name one. Check the vendor's site for a newer release. If there is none, fix the query code with prepared statements or stop using the application.
