CVE-2022-35299Network attack vector

Unauthenticated memory corruption via memory management errors

Published Oct 11, 2022 · Updated Aug 3, 2024

Stack-based buffer overflow in SAP SQL Anywhere 17.0 and SAP IQ 16.1 allows remote attackers to corrupt server memory over the network. SAP attributes the flaw to logical errors in memory management but does not disclose the affected function, processed input, or erroneous operation. Exploitation requires no authentication but does require the database server to run with a debugging option enabled; successful attacks can inject code into the server process.
