Description

Cross-site scripting (XSS) vulnerability in SendMailServlet in the examples web application (examples/jsp/mail/sendmail.jsp) in Apache Tomcat 4.0.0 through 4.0.6 and 4.1.0 through 4.1.36 allows remote attackers to inject arbitrary web script or HTML via the From field and possibly other fields, related to generation of error messages.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.tomcat:tomcat, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    No patched version of org.apache.tomcat:tomcat has shipped for CVE-2007-3383 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2007-3383 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2007-3383. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
