Vulnerability Details CVEID: CVE-2018-11771 DESCRIPTION: Apache Commons Compress is vulnerable to a denial of service, caused by the failure to return the correct EOF indication after the end of the stream has been reached by the ZipArchiveInputStream method. By reading a specially crafted ZIP archive, a remote attacker could exploit this vulnerability to cause the application to enter into an infinite loop. CVSS Base Score: 3.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 148429 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L) Affected Products and Versions The following product, running on all supported platforms, is affected: IBM InfoSphere Information Server: version 11.7.1.0 IBM InfoSphere Information Server on Cloud: version 11.7 Remediation/Fixes +-----------+---------+---------+-----------------------------------------------+ |Product |VRMF |APAR |Remediation/First Fix | +-----------+---------+---------+-----------------------------------------------+ |InfoSphere |11.7.1 |JR61522 |--Apply IBM InfoSphere Information Server | |Information| | |Connectivity Security patch | |Server, | | | | |Information| | | | |Server on | | | | |Cloud | | | | +-----------+---------+---------+-----------------------------------------------+ Workarounds and Mitigations None Change History 06 December 2019: Original version published Document Information Modified date: 06 December 2019 - -------------------------------------------------------------------------------- Security Bulletin: Multiple vulnerabilities in Jackson databind affect IBM InfoSphere Information Server Summary Multiple vulnerabilities in Jackson databind were addressed by IBM InfoSphere Information Server. Vulnerability Details CVEID: CVE-2019-12384 DESCRIPTION: FasterXML jackson-databind 2.x before 2.9.9.1 might allow attackers to have a variety of impacts by leveraging failure to block the logback-core class from polymorphic deserialization. Depending on the classpath content, remote code execution may be possible. CVSS Base score: 9.8 CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities /162849 for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2019-12086 DESCRIPTION: A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has the mysql-connector-java jar (8.0.14 or earlier) in the classpath, and an attacker can host a crafted MySQL server reachable by the victim, an attacker can send a crafted JSON message that allows them to read arbitrary local files on the server. This occurs because of missing com.mysql.cj.jdbc.admin.MiniAdmin validation. CVSS Base score: 5.3 CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities /161256 for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2019-14379 DESCRIPTION: SubTypeValidator.java in FasterXML jackson-databind before 2.9.9.2 mishandles default typing when ehcache is used (because of net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup), leading to remote code execution. CVSS Base score: 9.8 CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities /165286 for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2019-14439 DESCRIPTION: A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9.2. This occurs when Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the logback jar in the classpath. CVSS Base score: 5.3 CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities /164744 for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2019-12814 DESCRIPTION: A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x through 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has JDOM 1.x or 2.x jar in the classpath, an attacker can send a specifically crafted JSON message that allows them to read arbitrary local files on the server. CVSS Base score: 7.5 CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities /162875 for the current score.
