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

The Common Vulnerabilities and Exposures (CVE) system has identified a critical vulnerability in Ivanti’s ICS and Policy Secure products, labeled as CVE-2023-46805. This vulnerability allows a remote attacker to bypass authentication mechanisms, potentially gaining unauthorized access to restricted resources. This poses serious risks to all organizations using the affected Ivanti’s solutions due to the potential for system compromise or data<\/a> leakage. Given the severity score of 8.2, it is imperative that affected parties take immediate action to mitigate this vulnerability<\/a>.<\/p>\n

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

CVE ID: CVE-2023-46805
\nSeverity: High (CVSS: 8.2)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Ivanti ICS | 9.x, 22.x
\nIvanti Policy Secure<\/a> | All versions<\/p>\n

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

The authentication bypass vulnerability in Ivanti ICS and Ivanti Policy<\/a> Secure software occurs in the web component. This flaw allows remote attackers to access restricted resources by bypassing control<\/a> checks. Essentially, the software does not perform adequate checks to ensure that a user is properly authenticated before granting access to secured<\/a> resources. An attacker could exploit this vulnerability by sending specially crafted network<\/a> requests to the affected system, tricking it into granting access without proper authentication.<\/p>\n

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

Here’s a conceptual example of how an attacker might exploit this vulnerability<\/a> using a HTTP request:<\/p>\n

GET \/restricted\/resource HTTP\/1.1\nHost: target.example.com\nX-Forwarded-For: attacker_ip\n{ \"user_session\": \"fake_session_id\" }<\/code><\/pre>\n
In this example, the attacker sends a GET request to a restricted resource, including a fake user session<\/a> ID in the request. The vulnerable system<\/a> fails to properly validate this session ID and grants access to the restricted resource.<\/p>\n
Mitigation<\/strong><\/p>\n
To mitigate this vulnerability, Ivanti has released patches for the affected versions of ICS and Policy Secure<\/a>. It is highly recommended to apply these patches immediately. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by identifying and blocking suspicious requests. However, this is a temporary solution and does not replace the need for the application of the vendor’s patch. Be sure to consistently monitor your systems for any unusual activity and maintain an up-to-date inventory of all devices and applications to ensure no vulnerable versions<\/a> remain in your environment.<\/p>\n","protected":false},"excerpt":{"rendered":"
