CVE-2023-32567Network attack vector

Unauthenticated information disclosure via external entity resolution

Published Aug 10, 2023 · Updated Oct 9, 2024

XML external entity processing in Ivanti Avalanche before 6.4.1.236 allows remote attackers to disclose sensitive information via crafted XML. The decodeToMap method permits external entity resolution, causing the XML parser to fetch a supplied URI and embed its contents for processing. No authentication is required, and disclosure is limited to resources accessible to the parser running in the SYSTEM context.
