jasypt before 1.9.2 allows a timing attack against the password hash comparison.

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2017:3141 advisory.

  - jasypt: Vulnerable to timing attack against the password hash comparison (CVE-2014-9970)

  - jackson-databind: Deserialization vulnerability via readValue method of ObjectMapper (CVE-2017-7525)

  - hibernate-validator: Privilege escalation when running under the security manager (CVE-2017-7536)

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

An update for rh-sso7-keycloak is now available for Red Hat Single Sign-On 7.1 for RHEL 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. 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.

Red Hat Single Sign-On is a standalone server, based on the Keycloak project, that provides authentication and standards-based single sign-on capabilities for web and mobile applications.

This release of Red Hat Single Sign-On 7.1.3 serves as a replacement for Red Hat Single Sign-On 7.1.2, and includes several bug fixes and enhancements. For further information, refer to the Release Notes linked to in the References section.

Security Fix(es) :

* It was found that keycloak would accept a HOST header URL in the admin console and use it to determine web resource locations. An attacker could use this flaw against an authenticated user to attain reflected XSS via a malicious server. (CVE-2017-12158)

* It was found that the cookie used for CSRF prevention in Keycloak was not unique to each session. An attacker could use this flaw to gain access to an authenticated user session, leading to possible information disclosure or further attacks. (CVE-2017-12159)

* It was found that libpam4j did not properly validate user accounts when authenticating. A user with a valid password for a disabled account would be able to bypass security restrictions and possibly access sensitive information. (CVE-2017-12197)

* It was found that Keycloak oauth would permit an authenticated resource to obtain an access/refresh token pair from the authentication server, permitting indefinite usage in the case of permission revocation. An attacker on an already compromised resource could use this flaw to grant himself continued permissions and possibly conduct further attacks. (CVE-2017-12160)

Red Hat would like to thank Mykhailo Stadnyk (Playtech) for reporting CVE-2017-12158; Prapti Mittal for reporting CVE-2017-12159; and Bart Toersche (Simacan) for reporting CVE-2017-12160. The CVE-2017-12197 issue was discovered by Christian Heimes (Red Hat).

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2809 advisory.

    Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on the JBoss     Application Server.

    This release of Red Hat JBoss Enterprise Application Platform 7.0.8 serves as a replacement for Red Hat     JBoss Enterprise Application Platform 7.0.7, and includes bug fixes and enhancements, which are documented     in the Release Notes document linked to in the References.

    Security Fix(es):

    * It was found that when using remote logging with log4j socket server the log4j server would deserialize     any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log     event that, during deserialization, would execute arbitrary code in the context of the logger application.
    (CVE-2017-5645)

    * A vulnerability was found in Jasypt that would allow an attacker to perform a timing attack on password     hash comparison. (CVE-2014-9970)

    * It was found that an information disclosure flaw in Bouncy Castle could enable a local malicious     application to gain access to user's private information. (CVE-2015-6644)

    * It was found that while parsing the SAML messages the StaxParserUtil class of Picketlink replaces     special strings for obtaining attribute values with system property. This could allow an attacker to     determine values of system properties at the attacked system by formatting the SAML request ID field to be     the chosen system property which could be obtained in the InResponseTo field in the response.
    (CVE-2017-2582)

    * It was found that when the security manager's reflective permissions, which allows it to access the     private members of the class, are granted to Hibernate Validator, a potential privilege escalation can     occur. By allowing the calling code to access those private members without the permission an attacker may     be able to validate an invalid instance and access the private member value via     ConstraintViolation#getInvalidValue(). (CVE-2017-7536)

    The CVE-2017-2582 issue was discovered by Hynek Mlnarik (Red Hat) and the CVE-2017-7536 issue was     discovered by Gunnar Morling (Red Hat).
