Published: 13 August 2020
Summary
CVE-2020-17463 is a critical-severity SQL Injection (CWE-89) vulnerability in Thedaylightstudio Fuel Cms. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 4.8% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities 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
FUEL CMS version 1.4.7 contains an SQL injection vulnerability (CWE-89) that affects the col parameter in the administrative endpoints /pages/items, /permissions/items, and /navigation/items. The flaw permits unsanitized input to be passed directly into database queries, resulting in a CVSS 3.1 base score of 9.8.
An unauthenticated attacker with network access can supply a crafted col value to these endpoints and execute arbitrary SQL statements. Successful exploitation grants full read, write, and delete access to the underlying database, enabling data exfiltration, privilege escalation, or persistent compromise of the CMS installation.
The vendor addressed the issue in release 1.4.8, available from the project GitHub repository and the official getfuelcms.com site. Public exploit code demonstrating the injection has been published on Packet Storm.

Directly requires validation and sanitization of untrusted input such as the col parameter before it reaches database queries, blocking the SQL injection vector.
Mandates timely application of the vendor patch (1.4.8) that eliminates the unsanitized col-parameter flaw in the listed administrative endpoints.
Enforces access-control policy on the /pages/items, /permissions/items and /navigation/items endpoints so that unauthenticated network callers cannot reach the injectable code paths.
