In Webgalamb through 7.0, an arbitrary code execution vulnerability could be exploited remotely without authentication. Exploitation requires authentication bypass to access administrative functions of the site to upload a crafted CSV file with a malicious payload that becomes part of a PHP eval() expression in the subscriber.php file.

Analyst readout for executives and security teams

Plain-English summary

CVE-2018-19514 affects Webgalamb through version 7.0 and can allow remote arbitrary code execution without normal authentication. The reported path involves bypassing authentication to reach administrative functions, then abusing CSV subscriber import handling that is evaluated as PHP code. Evidence does not include CVSS, vendor fix details, or confirmed active exploitation.

Executive priority

Treat as a high-priority exposure if Webgalamb is present and internet-facing. Remote code execution can lead to full application compromise, but urgency depends on whether the product exists in your environment and whether administrative import paths are reachable.

Technical view

The vulnerability is described in Webgalamb through 7.0 where a crafted CSV upload reaches subscriber.php and becomes part of a PHP eval() expression. The CVE states exploitation requires authentication bypass to access administrative functions. Public references describe broader Webgalamb issues, but the provided bundle lacks patch, commit, or precise configuration details.

Likely exposure

Exposure is likely limited to organizations still running Webgalamb through 7.0, especially internet-facing deployments with reachable administrative or subscriber import functionality. The source bundle lists no CPEs or vendor metadata, so asset matching may require product fingerprinting and software inventory review.

Exploitation context

Public disclosure references exist, but the CVE is not marked in CISA KEV and the bundle provides no evidence of active exploitation. The issue is still serious because the described impact is remote code execution after authentication bypass and administrative CSV upload abuse.

Researcher notes

The bundle lacks CVSS, CWE, CPE, patch, and exploit-in-the-wild evidence. Analysis should stay anchored to Webgalamb through 7.0, authentication bypass to administrative functions, crafted CSV upload, and PHP eval() handling in subscriber.php.

Mitigation direction

  • Identify any Webgalamb deployments and confirm whether versions are 7.0 or earlier.
  • Check vendor or maintainer guidance for fixed versions or official remediation.
  • Restrict external access to Webgalamb administrative functions pending remediation.
  • Disable subscriber CSV import if it is not operationally required.
  • Retire or isolate unsupported Webgalamb instances if no fixed release is available.

Validation and detection

  • Search asset inventory for Webgalamb and confirm installed version numbers.
  • Verify administrative interfaces are not publicly reachable without intended controls.
  • Review whether subscriber CSV import functionality is enabled or exposed.
  • Check web and application logs for suspicious administrative access or CSV import activity.
  • Document compensating controls if no vendor patch can be confirmed.
