A critical SQL injection vulnerability in Campcodes Grocery Sales and Inventory System 1.0 allows unauthenticated remote attackers to compromise the database.

This vulnerability is a SQL injection flaw (CWE-89) triggered by the improper sanitization of the ID argument within the /ajax.php file. The attack is remotely exploitable and does not require authentication, allowing an adversary to interact directly with the backend database.

The ability to perform unauthorized SQL queries poses a severe risk to data confidentiality, integrity, and availability. With a CVSS score of 7.3, this flaw enables attackers to extract sensitive inventory or user data, modify records, or potentially disrupt service, leading to significant reputational and operational damage.

Immediate Action: As no official patch is currently identified, administrators should immediately restrict access to the /ajax.php endpoint or disable the affected functionality until a vendor update is released.

Proactive Monitoring: Review web server access logs for anomalous requests targeting /ajax.php, particularly those containing SQL syntax characters like single quotes, semicolons, or comment indicators.

Compensating Controls: Deploy a Web Application Firewall (WAF) rule to inspect and block incoming requests to /ajax.php that contain suspicious patterns characteristic of SQL injection attempts.

Public Exploit Available: Yes, a public proof-of-concept exists as documented in the GitHub issue referenced by the vulnerability record.

Given the availability of a public exploit and the lack of a formal vendor patch, this vulnerability presents a high risk to the environment. Security teams must prioritize isolating the affected system or implementing strict network-level access controls to prevent unauthorized interaction with the vulnerable endpoint while awaiting further guidance from the vendor.
