CVE-2022-0747
Published: 21 March 2022
Summary
CVE-2022-0747 is a critical-severity SQL Injection (CWE-89) vulnerability in Quantumcloud Infographic Maker. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 0.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The Infographic Maker WordPress plugin before version 4.3.8 contains an unauthenticated SQL injection vulnerability (CWE-89) with a CVSS 3.1 score of 9.8. The flaw exists because the plugin fails to validate or escape the post_id parameter before incorporating it into a SQL statement inside the qcld_upvote_action AJAX handler, which is reachable by both unauthenticated and authenticated users.
An attacker can send a crafted AJAX request containing malicious SQL via the post_id parameter to extract, modify, or delete database contents, and potentially escalate to full site compromise given the high impact on confidentiality, integrity, and availability.
The referenced WordPress plugin changeset and WPScan advisory indicate that the issue was addressed by releasing version 4.3.8, which adds proper validation and escaping for the affected parameter.
The CVE maintains a high EPSS score with a recorded peak of 0.9106 and current value of 0.8486.
