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.

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.

    It was discovered that Jackson Databind incorrectly handled deserialization. An attacker could possibly     use this issue to obtain sensitive information. (CVE-2018-11307, CVE-2019-12086, CVE-2019-12814)

    It was discovered that Jackson Databind incorrectly handled deserialization. An attacker could possibly     use this issue to execute arbitrary code or other unspecified impact.

    It was discovered that Jackson Databind incorrectly handled deserialization. An attacker could possibly     use this issue to execute XML entity (XXE) attacks. (CVE-2018-14720)

    It was discovered that Jackson Databind incorrectly handled deserialization. An attacker could possibly     use this issue to execute server-side request forgery (SSRF). (CVE-2018-14721)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

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.

- Update jackson-databind to version 2.9.9.3.

  - Update jackson-core to version 2.9.9.

  - Update jackson-annotations to version 2.9.9.

  - Update jackson-bom to version 2.9.9.

Resolves CVE-2019-12086, CVE-2019-12384, CVE-2019-12814, CVE-2019-14379, and CVE-14439.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
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.

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.
