`CVE-2002-0682`

7.5 High Mitigation candidate

Description

Cross-site scripting vulnerability in Apache Tomcat 4.0.3 allows remote attackers to execute script as other web users via script in a URL with the /servlet/ mapping, which does not filter the script when an exception is thrown by the servlet.

Exploitation Status

Working exploit published

A reviewed exploit catalogue carries this CVE. Somebody has published code a stranger can run.

Waratek Defense Posture

Mitigation candidate

A defect of the type ARMR addresses, with a fix path to work from and a working exploit already published. This is a claim on attention, not a scheduling commitment: no rule exists and none is scheduled.

Protection none
Action unverified patch rule
Review automated inferred
Record active

Decided by poc-derivable : An indexed exploit to reverse-engineer, where there is no source to read

Finding Promoted to MITIGATION-CANDIDATE: 1 public proof-of-concept exploit(s) are indexed for this CVE (exploit-db), but the affected code is not open source. That makes an ARMR patch rule a candidate rather than a plan — the exploit gives a reproducible entry point to trace inward from and a test to validate a hook against, which is what makes reverse engineering tractable at all. No rule exists and none is scheduled: the hook point must be recovered by decompiling the affected code, and a closer look may find none that ARMR can act on.

CVSS

7.5 v2.0 AV:N/AC:L/Au:N/C:P/I:P/A:P 1 metric

VRT selects the newest version's highest entry and publishes it as cvssScore, newest rather than largest because scores are not comparable across versions, and highest rather than first because the first entry is frequently a CNA placeholder scoring 0.0 over NVD's own analysis.

Pipeline policy audit (17 of 21 rules evaluated)

17 of 21 rules ran. The rest were never reached, because an earlier stage settled the CVE, a distinct claim from a rule that ran and found nothing.

# Rule Outcome Status Detail

identity: Does this identifier describe a vulnerability at all? first match wins

1 rejected no-match CVE Program withdrawal of this identifier

scope: Is the vulnerability ARMR's to address? first match wins

2 armr-patch-file no-match An ARMR patch file on disk for this CVE

3 armr-secure-rule-file no-match An ARMR security-rule template on disk for this CVE

4 manual-classification no-match A researcher's recorded decision for this specific CVE

5 manual classification no-match Manual classification of this CVE in the legacy dataset

6 non-java-upstream no-match A root cause in non-Java code: an OS kernel, a C library, or a bundled runtime

7 oracle-component no-match The defect being in a component of a tracked product the agent does not reach: JavaFX, the Java SE installer, the native WebLogic proxy plug-in. Oracle gives these no CPE of their own and names them only in the description.

8 osv-maven no-match An OSV.dev record of this CVE affecting a package published to Maven Central

9 cna-maven-package no-match An affected Maven artifact named by the CNA itself

10 known-cpe-product matched Queued for review Matches known products: apache/tomcat

11 cna-cpe-product not-reached A CPE the CNA published naming a tracked product. Oracle publishes these on advisory day, months before NVD.

12 oracle-advisory-family not-reached A tracked product family named in Oracle's own risk matrix. CPE cannot carry a suite name, only a module.

13 non-deployable-product not-reached The only affected product being a sealed appliance image, where Java runs but no -javaagent can be attached

14 unmatched-product not-reached No tracked product matched above, and none present at all

disposition: What do we do about one that is? cumulative: every rule gets a turn

15 patch-hint no-match A reference pointing at the upstream fix: a commit, a PR, a Red Hat bug

16 open-source-maven no-match The affected package being open source on Maven, so the fix can be read

17 poc-derivable decided it matched Mitigation candidate 1 public PoC(s) indexed in exploit-db, with no public source. The exploit is a starting point for deriving an ARMR patch rule by reverse engineering; nothing here establishes a hook point exists.

18 no-exploit skipped With no fix path, a public exploit, or a CISA record of one

19 secure-rule-match no-match A vulnerability class already blocked by an ARMR security rule

20 below-action-threshold no-match Severity is HIGH — only MEDIUM/LOW are deprioritized

21 no-exploit-published no-match A KEV listing, a CISA verdict of active exploitation, or a reviewed exploit catalogue carries this CVE — somebody has published a working exploit, so it stays a candidate
