CVE-2022-26314Network attack vector

Account takeover via predictable initial passwords

Published Mar 8, 2022 · Updated Aug 3, 2024

Weak password generation in Mendix Forgot Password before 3.2.2 and 3.3.0 through 3.5.0 allows remote attackers to take over accounts. The module creates initial passwords with an insecure generation process, but Siemens has not published the algorithm or specific entropy weakness. Siemens states only that exploitation requires specific situations and does not disclose the necessary configuration; successful guessing gives control of the affected account.
