Deeper analysis

This vulnerability is an authentication bypass issue in Ivanti Avalanche version 6.3.2.3490 stemming from a SQL injection flaw in the ProfileDaoImpl class. The weakness allows a crafted request containing a user-supplied string to be used directly in SQL query construction, enabling an attacker to circumvent the existing authentication mechanism despite the need for initial credentials. It carries a CVSS 3.1 score of 8.8 and is tracked as CWE-89.

Remote attackers who possess limited valid credentials can exploit the flaw over the network to bypass authentication entirely, resulting in full compromise of confidentiality, integrity, and availability on the affected system.

The referenced advisories and release notes indicate that the issue is addressed in Avalanche version 6.3.4, with the corresponding patch available from the vendor download site and further details published in ZDI-22-778.

The EPSS score for this CVE stands at 0.2905 with no material increase from a lower baseline.
