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

The Common Vulnerability and Exposures (CVE) system has recorded a critical security flaw identified as CVE-2025-55142. This vulnerability affects multiple Ivanti products, including Ivanti Connect Secure, Ivanti Policy Secure, Ivanti ZTA Gateway, and Ivanti Neurons for Secure Access. If exploited, this flaw allows an authenticated attacker with read-only admin privileges to manipulate authentication-related settings, potentially compromising the system or leading<\/a> to data leakage. Given the severity of the vulnerability<\/a> and the potential for significant harm, it’s crucial for organizations using these Ivanti products to understand this issue and take appropriate measures to mitigate it.<\/p>\n

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

CVE ID: CVE-2025-55142
\nSeverity: Critical (8.8 out of 10)
\nAttack Vector: Network
\nPrivileges Required: Low (Authenticated with Read-Only Admin access<\/a>)
\nUser Interaction: None
\nImpact: System compromise<\/a> or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Ivanti Connect Secure | Before 22.7R2.9 or 22.8R2
\nIvanti Policy Secure<\/a> | Before 22.7R1.6
\nIvanti ZTA Gateway | Before 2.8R2.3-723
\nIvanti Neurons for Secure Access | Before 22.8R1.4<\/p>\n

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

The vulnerability arises from a missing authorization<\/a> check in the affected Ivanti products. An authenticated user<\/a> with read-only admin privileges can exploit this flaw by sending a specially crafted request to the server. Since the server does not adequately verify the user’s permissions before processing the request, the attacker can modify authentication-related settings. This manipulation could potentially grant them higher privileges or even full control of the system<\/a>.<\/p>\n

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

Here’s a conceptual example, in the form of an HTTP request, of how the vulnerability might be exploited:<\/p>\n

PATCH \/api\/configure\/authentication HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\nAuthorization: Bearer [Insert Auth Token]\n{ \"admin_privileges\": \"full_control\" }<\/code><\/pre>\n
In this example, the attacker is sending a PATCH request to the `configure\/authentication` endpoint. The request aims to change the `admin_privileges` setting to “full_control”. Since the server doesn’t properly check the user’s authorization, it accepts and processes this request, potentially granting the attacker full control of the system<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
