CVE-2023-46223:
Ivanti Avalanche vulnerability analysis and mitigation
Overview
CVE-2023-46223 is a critical vulnerability in Ivanti Avalanche's WLAvalancheService component, discovered and reported by Trend Micro's Zero Day Initiative. The vulnerability was disclosed on December 19, 2023, affecting all supported versions of Avalanche (versions 6.3.1 and above), as well as older versions. This stack-based buffer overflow vulnerability allows attackers to send specially crafted data packets to the Mobile Device Server, potentially causing memory corruption (NVD, Ivanti Blog).
Technical details
The vulnerability is classified as a stack-based buffer overflow in the WLAvalancheService component. It has received a CVSS v3.1 base score of 9.8 (Critical), with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. The high severity score indicates that the vulnerability requires no authentication, is low complexity to exploit, and can be accessed remotely with no user interaction required (ZDI Advisory).
Impact
The successful exploitation of this vulnerability can lead to multiple severe consequences. An attacker can potentially achieve remote code execution in the context of SYSTEM privileges, cause denial of service conditions, or execute arbitrary code on affected installations. The vulnerability's critical nature stems from its potential to allow complete system compromise (ZDI Advisory, Bleeping Computer).
Mitigation and workarounds
Ivanti has released a patch to address this vulnerability in Avalanche version 6.4.2.313. Organizations are strongly recommended to upgrade to this version to mitigate the risk. The fix is available for all impacted versions of the product (Ivanti Blog, Release Notes).
