`CVE-2017-3261`

4.3 Medium Mitigated by environment configuration

Description

Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Networking). Supported versions that are affected are Java SE: 6u131, 7u121 and 8u112; Java SE Embedded: 8u111. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS v3.0 Base Score 4.3 (Confidentiality impacts).

CVSS

4.3 MEDIUM v3.0 CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N 2 metrics

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.

5 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 decided it matched Mitigated by environment configuration Found in legacy manual classifications

6 non-java-upstream not-reached A root cause in non-Java code: an OS kernel, a C library, or a bundled runtime

7 oracle-component not-reached 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 not-reached An OSV.dev record of this CVE affecting a package published to Maven Central

9 cna-maven-package not-reached An affected Maven artifact named by the CNA itself

10 known-cpe-product not-reached An NVD CPE naming a product ARMR tracks

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 not-reached A reference pointing at the upstream fix: a commit, a PR, a Red Hat bug

16 open-source-maven not-reached The affected package being open source on Maven, so the fix can be read

18 no-exploit not-reached With no fix path, a public exploit, or a CISA record of one

19 secure-rule-match not-reached A vulnerability class already blocked by an ARMR security rule

20 below-action-threshold not-reached Medium or Low severity, no KEV listing, no PoC clearing the evidence bar, no CISA verdict, no Oracle advisory

21 no-exploit-published not-reached A published working exploit for this candidate, not only a proof of concept, a forecast, or nothing at all
