CVE-2025-34228·PHP vulnerability

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 25.1.102 and Application prior to version 25.1.1413 (VA/SaaS deployments) contain a server-side request forgery (SSRF) vulnerability. The `/var/www/app/console_release/lexmark/update.php` script is reachable from the internet without any authentication. The PHP script builds URLs from user‑controlled values and then invokes either 'curl_exec()` or `file_get_contents()` without proper validation. Because the endpoint is unauthenticated, any remote attacker can supply a hostname and cause the server to issue requests to internal resources. This enables internal network reconnaissance, potential pivoting, or data exfiltration. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.

How to fix this CVE

Upgrade Vasion Print (formerly PrinterLogic) Virtual Appliance Host to version 25.1.102 or later, and the Application to version 25.1.1413 or later for VA/SaaS deployments. This vulnerability allows unauthenticated attackers to manipulate internal network requests through an exposed PHP script, potentially leading to reconnaissance of internal resources or data exfiltration. Immediate patching is critical as the vulnerable endpoint requires no authentication.

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

GET|POST /var/www/app/console_release/lexmark/update.php.*?(?:url|hostname|host|file)=(?!localhost|127\.0\.0\.1)

WAF mitigation (if patching is not yet possible)

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

Block all unauthenticated requests to /console_release/lexmark/update.php with HTTP 403 Forbidden; implement request parameter whitelisting to only allow safe, predetermined URLs in the update script.

How to check if you are affected

  1. Check installed PHP version: php -v
  2. Verify if the vulnerable /var/www/app/console_release/lexmark/update.php script exists: test -f /var/www/app/console_release/lexmark/update.php && echo 'File exists' || echo 'File not found'
  3. Search web server logs for requests to /console_release/lexmark/update.php: grep -r 'console_release/lexmark/update.php' /var/log/apache2/ /var/log/nginx/ 2>/dev/null
  4. Confirm patch by checking Vasion Print version in admin dashboard or via: cat /opt/vasion/version.txt (if applicable to your deployment)

FAQ

What is CVE-2025-34228?

CVE-2025-34228 is a server-side request forgery (SSRF) vulnerability in Vasion Print's unauthenticated update.php script that allows remote attackers to craft arbitrary requests to internal network resources, enabling reconnaissance and potential data exfiltration.

Is CVE-2025-34228 being actively exploited?

No, CVE-2025-34228 is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog and no public exploits have been released, though the vulnerability details have been disclosed by security researchers.

What versions of PHP are affected by CVE-2025-34228?

All versions of Vasion Print Virtual Appliance Host prior to 25.1.102 and Application versions prior to 25.1.1413 (VA/SaaS deployments) are affected; the vulnerability exists in the application layer rather than PHP itself.

How do I check if my server is vulnerable to CVE-2025-34228?

Run: curl -v http://your-server/var/www/app/console_release/lexmark/update.php 2>&1 | grep -E '(200|302|403)' — if you receive a 200 or 302 response without authentication, the endpoint is exposed and vulnerable.

Does Defensia detect CVE-2025-34228?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If PHP or Vasion Print is installed on a monitored server, CVE-2025-34228 will appear in your dashboard with remediation steps.

CVE-2026-28289CVSS 10FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. A patch bypass vulnerability for CVE-2026-27636 in FreeScout 1.8.206 and earlier allows any authenticated user with file upload permissions to achieve Remote Code Execution (RCE) on the server by uploading a malicious .htaccess file using a zero-width space character prefix to bypass the security check. The vulnerability exists in the sanitizeUploadedFileName() function in app/Http/Helper.php. The function contains a Time-of-Check to Time-of-Use (TOCTOU) flaw where the dot-prefix check occurs before sanitization removes invisible characters. This vulnerability is fixed in 1.8.207.
CVE-2025-46348CVSS 10YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the request to commence a site backup can be performed and downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create and download an archive without being authenticated. This could result in a malicious attacker making numerous requests to create archives and fill up the file system, or by downloading the archive which contains sensitive site information. This issue has been patched in version 4.5.4.
CVE-2025-47916CVSS 10Invision Community 5.0.0 before 5.0.7 allows remote code execution via crafted template strings to themeeditor.php. The issue lies within the themeeditor controller (file: /applications/core/modules/front/system/themeeditor.php), where a protected method named customCss can be invoked by unauthenticated users. This method passes the value of the content parameter to the Theme::makeProcessFunction() method; hence it is evaluated by the template engine. Accordingly, this can be exploited by unauthenticated attackers to inject and execute arbitrary PHP code by providing crafted template strings.
CVE-2025-25174CVSS 10Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in beeteam368 BeeTeam368 Extensions beeteam368-extensions allows PHP Local File Inclusion.This issue affects BeeTeam368 Extensions: from n/a through <= 1.9.4.
CVE-2025-62521CVSS 10ChurchCRM is an open-source church management system. Prior to version 5.21.0, a pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise. The vulnerability exists in `setup/routes/setup.php` where user input from the setup form is directly concatenated into a PHP configuration template without any validation or sanitization. Any parameter in the setup form can be used to inject PHP code that gets written to `Include/Config.php`, which is then executed on every page load. This is more severe than typical authenticated RCE vulnerabilities because it requires no credentials and affects the installation process that administrators must complete. Version 5.21.0 patches the issue.
