CVE-2012-3546
Description
From CVE.org
org/apache/catalina/realm/RealmBase.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.30, when FORM authentication is used, allows remote attackers to bypass security-constraint checks by leveraging a previous setUserPrincipal call and then placing /j_security_check at the end of a URI.
Statement
Tomcat 5.5 has reached the end of its supported upstream life-cycle, and the Apache Tomcat project no longer tests security flaws to determine whether they affect Tomcat 5.5. Red Hat has tested tomcat 5.5 as shipped with Red Hat Enterprise Linux 5 and JBoss Enterprise Web Server 1, and found that it is affected by this flaw. Patches for tomcat 5.5 to address this flaw have been provided.
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).
