Unauthenticated denial of service
Published Jul 20, 2021 · Updated Sep 25, 2024
Denial of service in Outside In Filters in Oracle Outside In Technology 8.5.5 allows remote attackers to cause crashes via HTTP. The vendor has not disclosed the specific parser operation or code locus that mishandles untrusted input. Exploitation requires a consuming application to pass attacker-controlled network data directly to the SDK; successful attacks hang or repeatedly crash that application, interrupting availability without reported confidentiality or integrity impact.
