CVE-2021-35048Public exploitNetwork attack vector

Authentication-token disclosure via unauthenticated XML SQL injection

Published Jun 25, 2021 · Updated Sep 17, 2024

SQL injection in Fidelis Network and Deception CommandPost before 9.3.7 and in 9.4 allows remote attackers to expose authentication tokens. One of two unauthenticated XML endpoints passes crafted request data into a database operation without neutralizing SQL syntax, producing a SQL error. Unauthenticated web access is sufficient; exploitation can dump CommandPost database contents, including reversibly encoded credentials.
