Deeper analysis

Customer Support System v1 contains a SQL injection vulnerability, tracked as CVE-2023-49547 and assigned CWE-89, that affects the username parameter processed by the endpoint /customer_support/ajax.php?action=login. The flaw received a CVSS 3.1 score of 9.8, reflecting network-accessible, unauthenticated exploitation with no required user interaction that can result in full confidentiality, integrity, and availability impact.

An unauthenticated remote attacker can supply crafted input to the login action and execute arbitrary SQL commands against the underlying database, enabling data exfiltration, authentication bypass, or modification of records stored by the application. The two public references consist of a GitHub proof-of-concept repository and the original SourceCodester project page for the vulnerable software; neither reference supplies mitigation guidance or patch details.

EPSS scores for the issue have remained low, moving only from a peak of 0.0760 to a current value of 0.0734.
