CVE-2024-31839

Vulnerability

Overview CVE-2024-31839 is a Cross-Site Scripting (XSS) vulnerability found in tiagorlampert's CHAOS remote administration tool version 5.0.1. The flaw resides in the sendCommandHandler function within the handler.go component. This XSS vulnerability can be exploited by a remote attacker to execute arbitrary JavaScript in the context of the application, leading to privilege escalation [1].

Exploitation

Conditions To exploit this vulnerability, an attacker does not need prior authentication or special network access. The attack vector is network-based and does not require user interaction. The attacker can inject malicious script payloads via crafted input that is not properly sanitized by the sendCommandHandler function. Once the payload is stored or reflected, it can be executed in the browser of an authenticated user, potentially allowing the attacker to perform actions on behalf of that user [1][2].

Impact

Successful exploitation enables privilege escalation, meaning the attacker can gain higher-level permissions within the CHAOS application. This could lead to unauthorized control over connected agents, access to sensitive data, and potentially full compromise of the affected system. The impact is amplified because CHAOS is a remote administration tool that manages multiple endpoints [2].

Mitigation

Status As of the publication date (2024-04-12), no official patch for version 5.0.1 has been confirmed. Users are advised to follow the vendor's repository for updates and consider applying security measures such as input validation and output encoding to mitigate XSS risks [1][2].
