vulnerability analysis and mitigation

CVE-2023-40023 affects yaklang, a programming language designed for cybersecurity. The vulnerability was discovered in the Yak Engine's Fuzztag component, allowing unauthorized local file reading through local file inclusion (LFI). The issue was disclosed on August 14, 2023, affecting versions prior to 1.2.4-sp1 (GitHub Advisory).

The vulnerability exists in the Yak Engine's Fuzztag component, which allows attackers to include files from the server's local file system through the web application. The issue received a CVSS v3.1 base score of 6.5 (Medium), with a vector string of CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N. This indicates the vulnerability is network-accessible, requires low attack complexity, needs no privileges, but does require user interaction (GitHub Advisory).

When exploited, this vulnerability can lead to the unintended exposure of sensitive data from the server's local file system, potentially enabling unauthorized access to confidential information. While the integrity and availability of the system remain unaffected, the confidentiality impact is rated as High (GitHub Advisory).

The vulnerability has been patched in version 1.2.4-sp1. Users are strongly advised to upgrade to this version or later. For those unable to upgrade immediately, it is recommended to avoid exposing vulnerable versions to untrusted input and to monitor for unexpected server behavior (GitHub Advisory).
