CPE, which stands for Common Platform Enumeration, is a standardized scheme for naming hardware, software, and operating systems. CPE provides a structured naming scheme to uniquely identify and classify information technology systems, platforms, and packages based on certain attributes such as vendor, product name, version, update, edition, and language.
CWE, or Common Weakness Enumeration, is a comprehensive list and categorization of software weaknesses and vulnerabilities. It serves as a common language for describing software security weaknesses in architecture, design, code, or implementation that can lead to vulnerabilities.
CAPEC, which stands for Common Attack Pattern Enumeration and Classification, is a comprehensive, publicly available resource that documents common patterns of attack employed by adversaries in cyber attacks. This knowledge base aims to understand and articulate common vulnerabilities and the methods attackers use to exploit them.

Apache Tomcat 5.5.0 through 5.5.29 and 6.0.0 through 6.0.26 might allow remote attackers to discover the server's hostname or IP address by sending a request for a resource that requires (1) BASIC or (2) DIGEST authentication, and then reading the realm field in the WWW-Authenticate header in the reply.

EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

CVE-2010-1157: Apache Tomcat information disclosure vulnerability
Severity: Low
Vendor: The Apache Software Foundation
Versions Affected:
- - Tomcat 6.0.0 to 6.0.26
- - Tomcat 5.5.0 to 5.5.29
Note: The unsupported Tomcat 3.x, 4.x and 5.0.x versions may also be
affected.
Description:
The "WWW-Authenticate" header for BASIC and DIGEST authentication includes a
realm name. If a <realm-name> element is specified for the application in
web.xml it will be used. However, a <realm-name> is not specified then
Tomcat will generate one using the code snippet:
request.getServerName() + ":" + request.getServerPort() In some
circumstances this can expose the local hostname or IP address of the
machine running Tomcat.
Example:
GET /application/j_security_check HTTP/1.0
HTTP/1.1 401 Unauthorized
Server: Apache-Coyote/1.1
WWW-Authenticate: Basic realm="tomcat01:8080"
Content-Type: text/html;charset=utf-8
Content-Length: 954
Date: Thu, 31 Dec 2009 12:18:11 GMT
Connection: close
Mitigation:
Administrators of web applications that use BASIC or DIGEST authentication
are recommended to set an appropriate realm name in the web application's
web.xml file.
Alternatively, the following patches may be used to change the default realm
to "Authentication required" (without the quotes):
- - Tomcat 6.0.x: http://svn.apache.org/viewvc?view=rev&rev=936540
- - Tomcat 5.5.x: http://svn.apache.org/viewvc?view=rev&rev=936541
These patches will be included in the next releases of Tomcat 5.5.x and
Tomcat 6.0.x. No release date has been set for the next Tomcat 5.5.x and
Tomcat 6.0.x releases.
