Evidence used

  • CISA confirms exploitation in the wild.
  • A structured source references public exploit or proof-of-concept material.
  • EPSS is 97.03% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Atlassian Confluence Server and Data Center and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

CISA KEV mirrored by ENISA

Confluence Server and Data Center had a path traversal vulnerability in the downloadallattachments resource. A remote attacker who has permission to add attachments to pages and / or blogs or to create a new space or a personal space or who has 'Admin' permissions for a space can exploit this path traversal vulnerability to write files to arbitrary locations which can lead to remote code execution on systems that run a vulnerable version of Confluence Server or Data Center. All versions of Confluence Server from 2.0.0 before 6.6.13 (the fixed version for 6.6.x), from 6.7.0 before 6.12.4 (the fixed version for 6.12.x), from 6.13.0 before 6.13.4 (the fixed version for 6.13.x), from 6.14.0 before 6.14.3 (the fixed version for 6.14.x), and from 6.15.0 before 6.15.2 are affected by this vulnerability.

01

What, why and how

Atlassian Confluence Server and Data Center contain a path traversal vulnerability in the downloadallattachments resource that may allow a privileged, remote attacker to write files. Exploitation can lead to remote code execution.

What

Atlassian Confluence Server and Data Center contain a path traversal vulnerability in the downloadallattachments resource that may allow a privileged, remote attacker to write files. Exploitation can lead to remote code execution.

Why

Attacker-controlled path data is not constrained to the intended directory before the application accesses a file.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Confirmed in the wild

CISA added this CVE to its Known Exploited Vulnerabilities catalogue on 2021-11-03.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.

Likely attack path

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-22 ↗

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'). The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.

Official EUVD record ↗
Canadian Centre for Cyber Security · English · AL19-007Critical Vulnerabilities in Atlassian Confluence Servers

The Cyber Centre is aware of the active exploitation of Atlassian Confluence Servers and Confluence Data Centers in recent weeks. Trusted researchers have identified targeted campaigns against Government Facilities Sectors that leverage multiple vulnerabilities. The exploitations are believed to be leveraging the following known vulnerabilities: CVE-2019-3395: A malicious actor is able to remotely exploit a Server-Side Request Forgery (SSRF) vulnerability in the WebDAV plugin to send arbitrary HTTP and WebDAV requests. CVE-2019-3396: A server-side template injection vulnerability in the Widget Connector Macro allows a malicious actor to remotely execute arbitrary code. CVE-2019-3398: A path traversal vulnerability in the “downloadallattachments” resource allows a malicious actor with specific permissions to remotely write files to arbitrary locations, which in turn could lead to remote code execution. An authenticated user would require one of the below permissions in order to execute this vulnerability: Add attachments to pages and/or blogs Create a new space or a personal space ‘Admin’ privileges for a space
