CVE-2013-4590
Description
It was found that several application-provided XML files, such as web.xml, content.xml, *.tld, *.tagx, and *.jspx, resolved external entities, permitting XML External Entity (XXE) attacks. An attacker able to deploy malicious applications to Tomcat could use this flaw to circumvent security restrictions set by the JSM, and gain access to sensitive information on the system. Note that this flaw only affected deployments in which Tomcat is running applications from untrusted sources, such as in a shared hosting environment.
Statement
This issue did not affect JBoss Web, as shipped with various Red Hat JBoss products.
This issue does affect Tomcat 5 as shipped by Red Hat Enterprise Linux 5. The risks in breaking compatibility associated with fixing this flaw outweigh the benefits of the fix, therefore Red Hat does not plan to fix this flaw in Red Hat Enterprise Linux 5. Additionally, note that Red Hat Enterprise Linux 5 is currently in reduced support phase, receiving only Critical security updates. For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/site/support/policy/updates/errata#Production_3_Phase
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
