Overview<\/strong><\/p>\n

A severe vulnerability has been identified in the Caido web security auditing toolkit. This vulnerability, tracked as CVE-2025-49004, affects Caido versions prior to 0.48.0 and can potentially lead to system compromise or data leakage. It is crucial for system administrators and cybersecurity professionals to be aware of the vulnerability, its effects, and the mitigation strategies available.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-49004
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: System compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Caido | Prior to 0.48.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability arises from the lack of protection against DNS rebinding in Caido. An attacker can load Caido on a domain they control, which allows a malicious website to hijack the authentication flow of Caido and achieve code execution. During the initial setup, a malicious website loaded in the browser can hijack the locally running Caido instance and achieve remote command execution. Even if the Caido instance is already configured, an attacker can initiate the authentication flow by performing DNS rebinding.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Given the nature of the vulnerability, an example of exploiting it would involve an attacker setting up a malicious website and forcing the victim to visit it. This could be done through phishing tactics or other social engineering methods.<\/p>\n

GET \/malicious_site HTTP\/1.1\nHost: attacker_controlled_domain.com\nUser-Agent: victim_browser<\/code><\/pre>\n
This request would force the victim’s browser to connect to the attacker-controlled domain, which then initiates the DNS rebinding attack, leading to remote command execution on the victim’s system through the Caido toolkit.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
The primary mitigation strategy is to upgrade to Caido version 0.48.0 or later, which includes a patch for this vulnerability. As a temporary measure, users can also employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to help detect and prevent potential exploitation of this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
