CVE-2025-34222·Docker vulnerability

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 22.0.1049 and Application prior to version 20.0.2786 (VA/SaaS deployments) expose four admin routes – /admin/hp/cert_upload, /admin/hp/cert_delete, /admin/certs/ca, and /admin/certs/serviceclients/{scid} – without any authentication check. The routes are defined in the /var/www/app/routes/web.php file inside the printercloud/pi Docker container and are handled by the HPCertificateController class, which performs no user validation. An unauthenticated attacker can therefore upload a new TLS/SSL certificate replacing the trusted root used by the appliance, delete an existing certificate causing immediate loss of trust for services that rely on it, or download any stored CA or client certificate via the service‑clients endpoint which also suffers an IDOR that allows enumeration of all client IDs. This vulnerability has been identified by the vendor as: V-2024-028 — Unauthenticated Admin APIs Used to Modify SSL Certificates.

How to fix this CVE

Update Docker to version 22.0.1049 or later to patch the unauthenticated certificate management endpoints in Vasion Print Virtual Appliance. If you are running a containerized Vasion Print deployment using Docker, ensure your host system Docker installation is current, and verify that your Vasion Print container image version is 22.0.1049 or above. Additionally, review network access controls to restrict admin API endpoints to trusted sources only.

sudo dnf update docker-ce

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST|DELETE|GET /admin/hp/cert_upload|/admin/hp/cert_delete|/admin/certs/ca|/admin/certs/serviceclients/\d+ HTTP/1\.1.*(?!Authorization|X-API-Key)

WAF mitigation (if patching is not yet possible)

Add this rule to your WAF to block exploitation attempts while you schedule the patch. 

Implement authentication middleware that requires valid API credentials (JWT, API key, or session token) for all requests matching patterns: ^/admin/hp/cert_(upload|delete)$, ^/admin/certs/ca$, and ^/admin/certs/serviceclients/. Return 401 Unauthorized for requests lacking valid credentials. Additionally, implement rate limiting on these endpoints and log all access attempts for audit trails.

How to check if you are affected

  1. Check your Docker version: docker --version
  2. Verify Vasion Print container version: docker inspect <container-id> | grep -i version or docker ps --format 'table {{.Image}}'
  3. Search for suspicious certificate upload/delete requests in Docker daemon logs: sudo journalctl -u docker -g 'admin/hp/cert' or check /var/log/docker.log for POST/DELETE requests to /admin/hp/cert_upload, /admin/hp/cert_delete, /admin/certs/ca, or /admin/certs/serviceclients
  4. Verify the fix by confirming Vasion Print version is 22.0.1049 or later: docker exec <container-id> cat /opt/app/VERSION or equivalent version file location

Indicators of compromise

  • /admin/hp/cert_upload
  • /admin/hp/cert_delete
  • /admin/certs/ca
  • /admin/certs/serviceclients

FAQ

What is CVE-2025-34222?

CVE-2025-34222 is a critical authentication bypass vulnerability in Vasion Print (formerly PrinterLogic) Virtual Appliance that allows unauthenticated attackers to upload, delete, or download TLS/SSL certificates through exposed admin API endpoints. This permits attackers to compromise certificate trust, intercept encrypted traffic, or enumerate sensitive client information.

Is CVE-2025-34222 being actively exploited?

No, CVE-2025-34222 is not currently listed on CISA's Known Exploited Vulnerabilities (KEV) catalog and has no public exploit available. However, the attack surface is trivial and requires no authentication, making it high-risk if exposed to untrusted networks.

What versions of Docker are affected by CVE-2025-34222?

This CVE specifically affects Vasion Print Virtual Appliance versions prior to 22.0.1049 and Application versions prior to 20.0.2786 running inside Docker containers. Update your Vasion Print container image to version 22.0.1049 or later. The Docker engine itself is not directly vulnerable; the issue lies in the containerized application.

How do I check if my server is vulnerable to CVE-2025-34222?

Run `docker ps --format 'table {{.Image}}'` to list running containers and identify Vasion Print instances, then use `docker inspect <container-id> | grep -E 'Image|Version'` to confirm the version is below 22.0.1049. Additionally, test network accessibility to /admin/hp/cert_upload without authentication using `curl -X POST http://<host>/admin/hp/cert_upload` — if it responds without a 401/403 error, the endpoint is exposed.

Does Defensia detect CVE-2025-34222?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Docker is installed on a monitored server and Vasion Print containers are running, CVE-2025-34222 will appear in your dashboard with remediation steps.

CVE-2026-53576CVSS 10Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.45 and 1.3.21, the authentication filter for the REST API (@Filter("/api/v1/**")) treats any request whose path ends in /configs as the public instance-config endpoint and forwards it without a credential check. kestra addresses its resources by URL path segments that the caller chooses (/api/v1/{tenant}/flows/{namespace}, /api/v1/{tenant}/executions/{namespace}/{id}, /api/v1/{tenant}/namespaces/{namespace}/kv/{key}). An anonymous caller picks the literal configs as the final segment, and the request bypasses Basic-Auth entirely. Because the bypass reaches the flow-create and execution-trigger routes, an unauthenticated caller creates a flow containing a Shell or Process task and runs it. The task executes as root inside the kestra container. The official docker-compose.yml mounts /var/run/docker.sock, so root in the container reaches the host Docker daemon. This vulnerability is fixed in 1.0.45 and 1.3.21.
CVE-2026-57572CVSS 10Crawl4AI is an open-source LLM-friendly web crawler and scraper. Prior to 0.9.0, the Docker API server accepted request-supplied browser_config.extra_args, which flowed into Chromium's launch arguments. An attacker could inject Chromium switches that replace a child-process launch command together with --no-zygote, causing Chromium to fork or exec an attacker-controlled command as the container's runtime user. The Docker API is unauthenticated by default, so a single request yields arbitrary command execution. This issue is fixed in version 0.9.0.
CVE-2026-40281CVSS 10Gotenberg is a Docker-powered stateless API for PDF files. In versions 8.30.1 and earlier, the metadata write endpoint validates metadata keys for control characters but leaves metadata values unsanitized. A newline character in a metadata value splits the ExifTool stdin line into two separate arguments, allowing injection of arbitrary ExifTool pseudo-tags such as -FileName, -Directory, -SymLink, and -HardLink. This is a bypass of the incomplete key-sanitization fix introduced in v8.30.1. An unauthenticated attacker can rename or move any PDF being processed to an arbitrary path in the container filesystem, overwrite arbitrary files, or create symlinks and hard links at arbitrary paths.
CVE-2026-42298CVSS 10Postiz is an AI social media scheduling tool. Prior to commit da44801, a "Pwn Request" vulnerability in the Build and Publish PR Docker Image workflow (.github/workflows/pr-docker-build.yml) allows any unauthenticated user to execute arbitrary code during the Docker build process and exfiltrate a highly privileged GITHUB_TOKEN (write-all permissions). This can be achieved simply by opening a Pull Request from a fork with a maliciously modified Dockerfile.dev. This issue has been patched via commit da44801.
CVE-2026-26216CVSS 10Crawl4AI versions prior to 0.8.0 contain a remote code execution vulnerability in the Docker API deployment. The /crawl endpoint accepts a hooks parameter containing Python code that is executed using exec(). The __import__ builtin was included in the allowed builtins, allowing unauthenticated remote attackers to import arbitrary modules and execute system commands. Successful exploitation allows full server compromise, including arbitrary command execution, file read and write access, sensitive data exfiltration, and lateral movement within internal networks.
