CVE-2023-30130

Deeper analysis

CraftCMS version 3.8.1 contains a code injection vulnerability tracked as CVE-2023-30130 and assigned CWE-94. The flaw resides in handling of the Section parameter and permits a remote attacker to supply a crafted script that results in arbitrary code execution on the server. The issue carries a CVSS 3.1 base score of 8.8, reflecting network attack vector, low complexity, no required privileges, and required user interaction.

An unauthenticated remote attacker can exploit the weakness by delivering a malicious payload through the Section parameter, typically via a crafted link or request that a user must interact with. Successful exploitation grants the attacker the ability to execute arbitrary code, leading to full compromise of confidentiality, integrity, and availability on the affected CraftCMS instance.

The provided references point to the vendor site and a technical write-up describing server-side template injection but contain no explicit mitigation guidance or patch details. The EPSS score reached a peak of 0.0840 before settling at the current value of 0.0713, indicating a modest post-disclosure increase in exploitation interest.
