Deserialization flaws were discovered in jackson-databind relating to EHCache and logback/jndi, which could allow an unauthenticated user to perform remote code execution. The issue was resolved by extending the blacklist and blocking more classes from polymorphic deserialization.

For Debian 8 'Jessie', these problems have been fixed in version 2.4.2-2+deb8u8.

We recommend that you upgrade your jackson-databind packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that jackson-databind, a Java library used to parse JSON and other data formats, did not properly validate user input before attempting deserialization. This allowed an attacker providing maliciously crafted input to perform code execution, or read arbitrary files on the server.

According to its self-reported version number, the Oracle Primavera Unifier installation running on the remote web server is 16.1.x or 16.2.x prior to 16.2.15.10, or 17.7.x through 17.12.x prior to 17.12.11.1, or 18.8.x prior to 18.8.13.0. It is, therefore, affected by multiple vulnerabilities:

    - An unspecified flaw exists in how 'default typing' is handled when 'ehcache' is used in the       jackson-databind component of Primavera Unifier. An unauthenticated, remote attacker can exploit this       via the network over HTTP to cause remote code execution. (CVE-2019-14379)

    - An information disclosure vulnerability exists in the jackson-databind component of Primavera Unifier.
      An unauthenticated, remote attacker can exploit this via an externally exposed JSON endpoint if the       service has the mysql-connector-java jar in the classpath, and the attacker can host a crafted MySQL       server accessible by the victim. An attacker can send a crafted JSON message to read arbitrary local       files on the server. (CVE-2019-12086)

    - An information disclosure vulnerability exists in the jackson-databind component of Primavera Unifier.
      An unauthenticated, remote attacker can exploit this via an externally exposed JSON endpoint if the       service has the logback jar in the classpath, which can allow information disclosure. (CVE-2019-14439)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4813-1 advisory.

  - An issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.5. Use of Jackson default typing     along with a gadget class from iBatis allows exfiltration of content. Fixed in 2.7.9.4, 2.8.11.2, and     2.9.6. (CVE-2018-11307)

  - An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default     Typing is enabled (either globally or for a specific property), the service has the Jodd-db jar (for     database access for the Jodd framework) in the classpath, and an attacker can provide an LDAP service to     access, it is possible to make the service execute a malicious payload. (CVE-2018-12022)

  - An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default     Typing is enabled (either globally or for a specific property), the service has the Oracle JDBC jar in the     classpath, and an attacker can provide an LDAP service to access, it is possible to make the service     execute a malicious payload. (CVE-2018-12023)

  - FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to execute arbitrary code by     leveraging failure to block the slf4j-ext class from polymorphic deserialization. (CVE-2018-14718)

  - FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to execute arbitrary code by     leveraging failure to block the blaze-ds-opt and blaze-ds-core classes from polymorphic deserialization.
    (CVE-2018-14719)

  - FasterXML jackson-databind 2.x before 2.9.7 might allow attackers to conduct external XML entity (XXE)     attacks by leveraging failure to block unspecified JDK classes from polymorphic deserialization.
    (CVE-2018-14720)

  - FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to conduct server-side request     forgery (SSRF) attacks by leveraging failure to block the axis2-jaxws class from polymorphic     deserialization. (CVE-2018-14721)

  - FasterXML jackson-databind 2.x before 2.9.8 might allow attackers to have unspecified impact by leveraging     failure to block the axis2-transport-jms class from polymorphic deserialization. (CVE-2018-19360)

  - FasterXML jackson-databind 2.x before 2.9.8 might allow attackers to have unspecified impact by leveraging     failure to block the openjpa class from polymorphic deserialization. (CVE-2018-19361)

  - FasterXML jackson-databind 2.x before 2.9.8 might allow attackers to have unspecified impact by leveraging     failure to block the jboss-common-core class from polymorphic deserialization. (CVE-2018-19362)

  - 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. (CVE-2019-12086)

  - 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. (CVE-2019-12384)

  - 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. (CVE-2019-12814)

  - 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. (CVE-2019-14379)

  - 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. (CVE-2019-14439)

    (CVE-2019-16335)

  - A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default     Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and     the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service     endpoint to access, it is possible to make the service execute a malicious payload. This issue exists     because of org.apache.commons.dbcp.datasources.SharedPoolDataSource and     org.apache.commons.dbcp.datasources.PerUserPoolDataSource mishandling. (CVE-2019-16942)

  - A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.10. When Default     Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and     the service has the p6spy (3.8.6) jar in the classpath, and an attacker can find an RMI service endpoint     to access, it is possible to make the service execute a malicious payload. This issue exists because of     com.p6spy.engine.spy.P6DataSource mishandling. (CVE-2019-16943)

  - A Polymorphic Typing issue was discovered in FasterXML jackson-databind before 2.9.10. It is related to     net.sf.ehcache.hibernate.EhcacheJtaTransactionManagerLookup. (CVE-2019-17267)
