Summary

CVE-2019-25703 is a high-severity SQL Injection (CWE-89) vulnerability in Impresscms Impresscms. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2019-25703 is a time-based blind SQL injection vulnerability in ImpressCMS 1.3.11. The issue resides in the admin.php endpoint, where the 'bid' parameter is vulnerable to manipulation, allowing attackers to inject SQL code into database queries.

Authenticated attackers with low privileges can exploit this vulnerability remotely with low attack complexity and no user interaction. By sending POST requests to admin.php containing malicious 'bid' values with SQL commands, they can extract sensitive database information, resulting in high confidentiality impact, low integrity impact, and no availability impact (CVSS 7.1; AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N; CWE-89).

Advisories and references include the ImpressCMS official site, a SourceForge download for version 1.3.11, an Exploit-DB entry (46239) demonstrating the exploit, and a VulnCheck advisory detailing the SQL injection via the 'bid' parameter.
