CVE-2023-2418

Information disclosure via insufficiently random login values

Published Apr 29, 2023 · Updated Aug 2, 2024

Use of insufficiently random values in the Konga 2.8.3 Login API allows attackers to disclose sensitive information from an adjacent network. The CNA does not identify the affected function, the generated value, or how Login API input causes the value to become predictable. Exploitation requires no account or user interaction but does require adjacent access and unspecified high-complexity conditions.
