SQL Injection Vulnerability in GG Soft Software Services Inc. Paperwork

GG Soft Software Services Inc. Paperwork, in versions released through 2026-09-09, contains a critical SQL injection vulnerability identified as CVE-2026-85215. This vulnerability stems from improper neutralization of special elements used in SQL commands within the application's database interaction layer. An unauthenticated attacker can exploit this flaw by supplying maliciously crafted inputs to vulnerable endpoints. Successful exploitation allows for the execution of arbitrary SQL queries, which may lead to unauthorized data retrieval, modification, or deletion of the backend database content. Given the severity of the potential impact, organizations using affected versions of Paperwork should restrict internet-facing access to the application and monitor database logs for anomalous query patterns.

Impact

Successful exploitation of CVE-2026-85215 grants attackers unauthorized access to the underlying application database. Depending on the privileges assigned to the database user account used by the Paperwork application, this could result in complete data exfiltration, unauthorized modification of sensitive administrative settings, or deletion of critical business information.

Recommendation

• Audit all internet-facing instances of GG Soft Paperwork and ensure they are patched to versions released after 2026-09-09.
• Implement web application firewall (WAF) rules to detect and block common SQL injection patterns targeting URI parameters and input fields.
• Review database query logs for suspicious SQL syntax, such as UNION SELECT, SLEEP(), or heavy use of comment characters like '--' or '/*'.
• Restrict access to the Paperwork management interface to authorized networks using VPNs or internal network segmentation.
