CVE-2006-3835· NVD / CVE Program· CNA mitre

Apache Tomcat 5 before 5.5.17 allows remote attackers to list directories via a semicolon (;) preceding a filename with a mapped extension,

Noroxi assessment

Priority: Monitor (action score 34/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 46.2% (FIRST EPSS); higher than 98.8% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: org.apache.tomcat:tomcat (Maven) 5.5.17; ant (Red Hat:certificate_system:7.3) 0:1.6.5-1jpp_1rh; avalon-logkit (Red Hat:certificate_system:7.3) 0:1.2-2jpp_4rh.

Low priority for now. Upgrade to org.apache.tomcat:tomcat (Maven) 5.5.17; ant (Red Hat:certificate_system:7.3) 0:1.6.5-1jpp_1rh; avalon-logkit (Red Hat:certificate_system:7.3) 0:1.2-2jpp_4rh or later.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
