Huawei EulerOS: Security Advisory for tomcat (EulerOS-SA-2017-1192)

Published: 2020-01-23 10:57:27
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:N

Summary:
The remote host is missing an update for the Huawei EulerOS 'tomcat' Linux Distribution Package(s) announced via the EulerOS-SA-2017-1192 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
The Realm implementations did not process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder. (CVE-2016-0762) It was discovered that a malicious web application could bypass a configured SecurityManager via a Tomcat utility method that was accessible to web applications. (CVE-2016-5018) It was discovered that when a SecurityManager was configured, Tomcat's system property replacement feature for configuration files could be used by a malicious web application to bypass the SecurityManager and read system properties that should not be visible. (CVE-2016-6794) It was discovered that a malicious web application could bypass a configured SecurityManager via manipulation of the configuration parameters for the JSP Servlet. (CVE-2016-6796) It was discovered that it was possible for a web application to access any global JNDI resource whether an explicit ResourceLink had been configured or not. (CVE-2016-6797) A vulnerability was discovered in tomcat. When running an untrusted application under a SecurityManager it was possible, under some circumstances, for that application to retain references to the request or response objects and thereby access and/or modify information associated with another web application.(CVE-2017-5648) A vulnerability was discovered in the error page mechanism in Tomcat's DefaultServlet implementation. A crafted HTTP request could cause undesired side effects, possibly including the removal or replacement of the custom error page.(CVE-2017-5664)

Affected Versions:
'tomcat' Linux Distribution Package(s) on Huawei EulerOS V2.0SP2.

Recommendations:
Please install the updated Linux Distribution Package(s).

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
