CVE-2024-7593: Ivanti Virtual Traffic Manager Authentication Bypass Vulnerability

CVE-2024-7593 is rated critical with a CVSS v3.1 base score of 9.8 and affects Ivanti Virtual Traffic Manager. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available. CISA added it to its Known Exploited Vulnerabilities catalog on 2024-09-24, which means exploitation in the wild has been observed.

Vulnerability description

Incorrect implementation of an authentication algorithm in Ivanti vTM other than versions 22.2R1 or 22.7R2 allows a remote unauthenticated attacker to bypass authentication of the admin panel.

Availability impact: High. Total loss of availability; the component can be shut down.

Underlying weakness

CWE-287: Improper Authentication

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

CWE-303: Incorrect Implementation of Authentication Algorithm

The requirements for the product dictate the use of an established authentication algorithm, but the implementation of the algorithm is incorrect.

Affected products

Ivanti Virtual Traffic Manager: 22.2; 22.3; 22.3 r2; 22.5 r1; 22.6 r1; 22.7 r1
