Deeper analysis
CVE-2023-46262 is a server-side request forgery vulnerability (CWE-918) affecting the Remote Control server component of Ivanti Avalanche. An unauthenticated attacker can trigger the flaw by sending a specifically crafted web request, resulting in a CVSS 7.5 impact that allows high confidentiality exposure without requiring privileges or user interaction.
The attack can be carried out remotely over the network by any party able to reach the affected server. Successful exploitation enables the attacker to cause the server to make outbound requests to arbitrary destinations, potentially disclosing sensitive internal resources or services that would otherwise be inaccessible.
The supplied references point to the Avalanche 6.4.2 release notes, indicating that the vendor addressed the issue in that version.
EPSS for the CVE rose from lower values to a peak of 0.5023 on 2025-12-11 before receding to the current 0.3172, showing a clear post-disclosure increase in exploitation interest that warrants renewed attention.
