Vulnerability from github – Published: 2023-08-09 09:30 – Updated: 2024-11-18 16:26

Details

An authenticated attacker with administrative access to the appliance can inject malicious JavaScript code inside the definition of a Threat Intelligence rule, that will later be executed by another legitimate user viewing the details of such a rule. An attacker may be able to perform unauthorized actions on behalf of legitimate users. JavaScript injection was possible in the content for Yara rules, while limited HTML injection has been proven for packet and STYX rules. The injected code will be executed in the context of the authenticated victim's session.

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.
