CVE-2020-36972
Published: 28 January 2026
Summary
CVE-2020-36972 is a high-severity SQL Injection (CWE-89) vulnerability in Smartdatasoft Smartblog. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 19.8th 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 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2020-36972 is a blind SQL injection vulnerability in SmartBlog 2.0.1, specifically within the 'id_post' parameter of the details controller. This flaw allows attackers to extract database information by injecting crafted SQL queries that systematically test and retrieve contents character by character. It is classified under CWE-89 and carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N).
Unauthenticated remote attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required. Exploitation enables the systematic extraction of sensitive database contents, resulting in high confidentiality impact and low integrity impact, while availability remains unaffected.
