This vulnerability is not remotely exploitable without authentication, i.e., may not be exploited over a network without requiring user credentials." [1] CVE-2021-2464 7.8 AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Supported versions that are affected are 12.1.0.2, 19c and 21c. Easily exploitable vulnerability allows low privileged attacker having Local Logon privilege with logon to the infrastructure where the affected system executes to compromise the affected system. Successful attacks of this vulnerability can result in takeover of the affected system. Affects: o Engineered Systems Utilities 12.1.0.2, 19c, 21c MITIGATION Oracle states: "Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply CPU fixes as soon as possible. Until you apply the CPU fixes, it may be possible to reduce the risk of successful attack by blocking network protocols required by an attack. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from users that do not need the privileges may help reduce the risk of successful attack. Both approaches may break application functionality, so Oracle strongly recommends that customers test changes on non-production systems. Neither approach should be considered a long-term solution as neither corrects the underlying problem."
