There is a timing window where there could be a privilege escalation vulnerability in WebSphere Application Server. There is a potential remote code execution vulnerability in WebSphere Application Server. There is a potential cross-site request forgery in WebSphere Application Server Admin Console. There is a potential XXE injection vulnerability in the Knowledge Center used by WebSphere Application Server. There is a potential information disclosure in WebSphere Application Server. There is a potential for weaker than expected security in WebSphere Application Server with SP800-131 transition mode and SSL_TLSv2. There is a potential denial of service with the Google Guava library that is used in WebSphere Application Server. Vulnerability Details CVEID: CVE-2018-1901 DESCRIPTION: IBM WebSphere Application Server could allow a remote attacker to temporarily gain elevated privileges on the system, caused by incorrect cached value being used. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152530 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L) CVEID: CVE-2018-1904 DESCRIPTION: IBM WebSphere Application Server could allow remote attackers to execute arbitrary Java code through an administrative client class with a serialized object from untrusted sources. CVSS Base Score: 8.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152533 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2018-1905 DESCRIPTION: IBM WebSphere Application Server is vulnerable to a XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. CVSS Base Score: 7.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152534 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L) CVEID: CVE-2018-1926 DESCRIPTION: IBM WebSphere Application Server Admin Console is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input. By persuading a user to visit a malicious URL, a remote attacker could send a specially-crafted request. An attacker could exploit this vulnerability to perform CSRF attack and update available applications. CVSS Base Score: 4.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152992 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) CVEID: CVE-2018-1957 DESCRIPTION: IBM WebSphere Application Server could allow sensitive information to be available caused by mishandling of data by the application based on an incorrect return by the httpServletRequest#authenticate() API when an unprotected URI is accessed. CVSS Base Score: 4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 153629 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2018-1996 DESCRIPTION: IBM WebSphere Application Server could provide weaker than expected security, caused by the improper TLS configuration. A remote attacker could exploit this vulnerability to obtain sensitive information using man in the middle techniques. CVSS Base Score: 5.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 154650 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N) CVEID: CVE-2018-10237 DESCRIPTION: Google Guava is vulnerable to a denial of service, caused by improper eager allocation checks in the AtomicDoubleArray and CompoundOrdering class. By sending a specially-crafted data, a remote attacker could exploit this vulnerability to cause a denial of service condition. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 142508 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Affected Products and Versions This vulnerability affects the following versions and releases of IBM WebSphere Application Server in IBM Cloud: o Liberty o Version 9.0 o Version 8.5 Remediation/Fixes To patch an existing service instance, refer to the IBM WebSphere Application Server bulletins listed below o Potential Privilege Escalation Vulnerability in WebSphere Application Server (CVE-2018-1901) o Potential Remote code execution vulnerability in WebSphere Application Server (CVE-2018-1904) o Potential XML External Entity (XXE) Injection Vulnerability in WebSphere Application Server (CVE-2018-1905) o Potential cross-site request forgery in WebSphere Application Server Admin Console (CVE-2018-1926) o Potential information disclosure in WebSphere Application Server (CVE-2018-1957) o Weaker than expected security in WebSphere Application Server with SP800-131 transition mode (CVE-2018-1996) o Potential denial of service in WebSphere Application Server (CVE-2018-10237) Please see Updating your environment in the KnowlegeCenter for information on applying service.
