Detailsinfo

A vulnerability has been found in Log2Space Subscriber Management Software 1.1 and classified as critical. Affected by this vulnerability is an unknown functionality of the file /l2s/api/selfcareLeadHistory of the component POST Handler. The manipulation of the argument lead_id with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Log2Space Subscriber Management Software 1.1 is vulnerable to unauthenticated SQL injection via the `lead_id` parameter in the `/l2s/api/selfcareLeadHistory` endpoint. A remote attacker can exploit this by sending a specially crafted POST request, resulting in the execution of arbitrary SQL queries. The backend fails to sanitize the user input, allowing enumeration of database schemas, table names, and potentially leading to full database compromise.
