SerializableProvider in RESTEasy in Red Hat Enterprise Linux Desktop 7, Red Hat Enterprise Linux HPC Node 7, Red Hat Enterprise Linux Server 7, and Red Hat Enterprise Linux Workstation 7 allows remote attackers to execute arbitrary code.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7630-1 advisory.

    It was discovered that RESTEasy made insufficient use of random values in asynchronous jobs. An attacker     could possibly use this issue to steal user data. This issue only affected Ubuntu 14.04 LTS.
    (CVE-2016-6345)

    It was discovered that RESTEasy enabled a vulnerable GZIP decompression module by default. An attacker     could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 LTS.
    (CVE-2016-6346)

    It was discovered that RESTEasy improperly made use of unsanitized data while handling certain errors. An     attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue     only affected Ubuntu 14.04 LTS. (CVE-2016-6347)

    It was discovered that RESTEasy enabled a vulnerable JSON manipulation module by default. An attacker     could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only     affected Ubuntu 14.04 LTS. (CVE-2016-6348)

    It was discovered that RESTEasy enabled a vulnerable deserialization module by default. An attacker could     possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected     Ubuntu 14.04 LTS. (CVE-2016-7050)

    Nikos Papadopoulos discovered that RESTEasy improperly handled URL encoding when certain errors occur. An     attacker could possibly use this issue to modify the app's behavior for other users throughout the     network. This issue did not affect resteasy3.0 in Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04.
    (CVE-2020-10688)

    Mirko Selber discovered that RESTEasy improperly validated user input during HTTP response construction.
    An attacker could possibly use this issue to to cause a denial of service or execute arbitrary code. This     issue did not affect resteasy3.0 in Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04.
    (CVE-2020-1695)

    It was discovered that RESTEasy improperly handled receiving the WebApplicationException during a client     call. An attacker could possibly use this issue to obtain potentially sensitive server information.
    (CVE-2020-25633)

    It was discovered that RESTEasy improperly populated exception responses with endpoint class and method     names. An attacker could possibly use this issue to obtain potentially sensitive server information.
    (CVE-2021-20289)

    It was discovered that RESTEasy used improper permissions when creating temporary files. An attacker could     possibly use this issue to get access to sensitive data. (CVE-2023-0482)

    It was discovered that RESTEasy improperly handled certain HTTP requests containing ASCII control     characters. An attacker could possibly use this issue to cause a denial of service. (CVE-2024-9622)

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 the version of the resteasy-base packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - It was discovered that under certain conditions     RESTEasy could be forced to parse a request with     SerializableProvider, resulting in deserialization of     potentially untrusted data. An attacker could possibly     use this flaw execute arbitrary code with the     permissions of the application using     RESTEasy.(CVE-2016-7050)

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

Security Fix(es) :

  - It was discovered that under certain conditions RESTEasy     could be forced to parse a request with     SerializableProvider, resulting in deserialization of     potentially untrusted data. An attacker could possibly     use this flaw to execute arbitrary code with the     permissions of the application using RESTEasy.
    (CVE-2016-7050)

Additional Changes :

An update for resteasy-base is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

RESTEasy contains a JBoss project that provides frameworks to help build RESTful Web Services and RESTful Java applications. It is a fully certified and portable implementation of the JAX-RS specification.

Security Fix(es) :

* It was discovered that under certain conditions RESTEasy could be forced to parse a request with SerializableProvider, resulting in deserialization of potentially untrusted data. An attacker could possibly use this flaw to execute arbitrary code with the permissions of the application using RESTEasy. (CVE-2016-7050)

Red Hat would like to thank Mikhail Egorov (Odin) for reporting this issue.
