CVE-2023-22843 (GCVE-0-2023-22843)

Vulnerability from cvelistv5 – Published: 2023-08-09 08:46 – Updated: 2024-09-20 12:04

Title

Stored Cross-Site Scripting (XSS) in Threat Intelligence rules in Guardian/CMC before 22.6.2

Summary

An authenticated attacker with administrative access to the web management interface can inject malicious JavaScript code inside the definition of a Threat Intelligence rule, that will be stored and can later be executed by another legitimate user viewing the details of such a rule. Via stored Cross-Site Scripting (XSS), an attacker may be able to perform unauthorized actions on behalf of legitimate users and/or gather sensitive information. JavaScript injection was possible in the contents for Yara rules, while limited HTML injection has been proven for packet and STYX rules.
