Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

SI-10 mandates information input validation at critical entry points like the 'bid' parameter in admin.php to directly prevent SQL injection exploitation.

SI-2 Flaw Remediation good match

prevent

SI-2 requires timely identification, reporting, and remediation of flaws such as the SQL injection vulnerability in ImpressCMS 1.3.11.

RA-5 Vulnerability Monitoring and Scanning good match

detect

RA-5 employs vulnerability scanning to detect SQL injection vulnerabilities like CVE-2019-25703 in the system.

NVD Description

ImpressCMS 1.3.11 contains a time-based blind SQL injection vulnerability that allows authenticated attackers to manipulate database queries by injecting SQL code through the 'bid' parameter. Attackers can send POST requests to the admin.php endpoint with malicious 'bid' values containing SQL…

commands to extract sensitive database information.

Deeper analysisAI

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.
