-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 =========================================================================== AUSCERT Security Bulletin ASB-2018.0014 Multiple vulnerabilities have been identified in Oracle Database Server 17 January 2018 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Oracle Database Server Operating System: Windows UNIX variants (UNIX, Linux, OSX) Impact/Access: Execute Arbitrary Code/Commands -- Remote/Unauthenticated Modify Arbitrary Files -- Remote with User Interaction Read-only Data Access -- Remote with User Interaction Resolution: Patch/Upgrade CVE Names: CVE-2018-2699 CVE-2018-2680 CVE-2018-2575 CVE-2017-12617 CVE-2017-10282 Member content until: Friday, February 16 2018 Reference: ESB-2017.2487 OVERVIEW Multiple vulnerabilities have been identified in Application Express versions prior to 5.1.4.00.08 and Oracle Database Server, versions 11.2.0.4, 12.1.0.2, 12.2.0.1. [1] IMPACT The vendor has provided the following information regarding the vulnerabilities: "This Critical Patch Update contains 5 new security fixes for the Oracle Database Server. 3 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials. 1 of these fixes is applicable to client-only installations, i.e., installations that do not have the Oracle Database Server installed." [1] "CVE-2017-10282 9.1 AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H Easily exploitable vulnerability allows high privileged attacker having Create Session, Execute Catalog Role privilege with network access via Oracle Net to compromise Core RDBMS. While the vulnerability is in Core RDBMS, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Core RDBMS. CVE-2018-2680 8.3 AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java VM. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java VM, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java VM. CVE-2017-12617 8.1 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise WLM (Apache Tomcat). Successful attacks of this vulnerability can result in takeover of WLM (Apache Tomcat). CVE-2018-2699 6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Application Express. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Application Express, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Application Express accessible data as well as unauthorized read access to a subset of Application Express accessible data. CVE-2018-2575 2.0 AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:N/A:N Difficult to exploit vulnerability allows high privileged attacker having Local Logon privilege with network access via multiple protocols to compromise Core RDBMS. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Core RDBMS accessible data. Note: Applicable only to Windows platform." [2] 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."
