What is CVE-2023-35853?

Prior to version 6.0.13, Suricata is susceptible to a vulnerability that allows an attacker with control over Lua rules to execute arbitrary Lua code. This poses significant security risks, as it can enable malicious actions within the system. The issue has been mitigated in version 6.0.13 by altering the default Lua configuration to disable code execution unless explicitly permitted via the allow-rules setting.
