Noroxi assessment

Priority: Plan (action score 47/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 50.8% (FIRST EPSS); higher than 98.9% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: tomcat8 (Debian:8) 8.0.14-1+deb8u15; org.apache.tomcat:tomcat-catalina (Maven) 7.0.72, 8.5.5; tomcat6 (Red Hat:enterprise_linux:6::client) 0:6.0.24-98.el6_8.

Add it to your regular patch cycle. Upgrade to tomcat8 (Debian:8) 8.0.14-1+deb8u15; org.apache.tomcat:tomcat-catalina (Maven) 7.0.72, 8.5.5; tomcat6 (Red Hat:enterprise_linux:6::client) 0:6.0.24-98.el6_8 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Apache Tomcat 7.x through 7.0.70 and 8.x through 8.5.4, when the CGI Servlet is enabled, follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "A mitigation is planned for future releases of Tomcat, tracked as CVE-2016-5388"; in other words, this is not a CVE ID for a vulnerability.
