CVE-2025-63939 -- CVSS 9.8 Vulnerability Briefing

CVE-2025-63939 | CVSS 9.8 (Critical) | Exploit: No known exploit

What Is It

CVE-2025-63939 is a SQL injection vulnerability in the Grocery Store Management System version 1.0, developed by anirudhkannan, specifically affecting the search endpoint at /Grocery/search_products_itname.php.

Technical Detail

The flaw exists due to improper input validation of the sitem_name POST parameter in the product search functionality, allowing an unauthenticated or authenticated attacker to inject arbitrary SQL statements into the backend database query. Successful exploitation can result in unauthorized data extraction, modification or deletion of database contents, and potentially full database compromise depending on the database user's privilege level. In worst-case configurations where the database account has elevated permissions, exploitation could extend to operating system command execution via database-native functions such as xp_cmdshell or INTO OUTFILE.

Exploitation Status

No known exploit code has been publicly documented for this vulnerability at this time, and it is not listed in CISA's Known Exploited Vulnerabilities catalog. The absence of a confirmed exploit does not reduce the severity, as SQL injection vulnerabilities of this class are straightforward to exploit manually or with widely available tooling such as sqlmap.

Who Is Targeting This

No specific threat actor attribution at this time. The affected software appears to be a small-scale open source project, which may limit broad targeting, but opportunistic attackers scanning for exposed web application endpoints could identify and exploit this vulnerability without significant effort.

What To Do

No official patch has been confirmed as of the date of this briefing; organizations running Grocery Store Management System 1.0 should treat the application as untrustworthy for production use until a remediated version is released. As an immediate workaround, restrict access to the /Grocery/search_products_itname.php endpoint via web server access controls or a web application firewall with SQL injection rule sets enabled. Database accounts used by the application should be reviewed and restricted to the minimum required privileges. Monitor web server and database logs for anomalous POST requests to the affected endpoint containing SQL metacharacters such as single quotes, comment sequences, or UNION-based payloads as detection signals.
