CVE-2021-47909

Root

Cause

Mult-E-Cart Ultimate 2.4 (v2021) contains multiple classic SQL injection vulnerabilities. The flaws reside in the id parameter used within the view and update functions of the inventory, customer, vendor, and order modules [1][3]. By failing to properly sanitize user-supplied input before incorporating it into SQL queries, the application allows an attacker to inject malicious SQL commands [1].

Exploitation

Exploitation is remote and does not require user interaction, but it does require an authenticated session with either vendor or administrator privileges [1]. An attacker can craft a malicious HTTP request—typically by manipulating the id parameter in a GET or POST request—to alter the intended SQL query [1]. The reference advisory indicates that the attacker's privileges must be at least those of a moderator (vendor or admin) to access the vulnerable functions [1].

Impact

Successful exploitation allows a remote attacker to execute arbitrary SQL commands against the underlying database management system [3]. This can lead to unauthorized reading or modification of sensitive data, privilege escalation, or complete compromise of the database server [1][3]. The CVSS v3 base score assigned is 8.1 (High), reflecting the high potential for data loss or system takeover.

Mitigation

As of the publication date, the vendor has not released a patched version, and no practical workaround is documented [1][3]. Users of Mult-E-Cart Ultimate 2.4 should consider restricting network access to the application, implementing a web application firewall, and monitoring for suspicious requests targeting the id parameter. Given that the product is end-of-life or unsupported, migration to an actively maintained platform may be the most effective mitigation [2][3].
