New CVE Detected

CVE-2026-49827 – Unauthenticated RCE via Arbitrary File Upload – WebErpMesv2 ≤ 1.19

Be the first to know when new zero-days emerge:

Summary

CVE-2026-49827 is a critical unrestricted file upload vulnerability in WebErpMesv2, a web-based manufacturing execution and resource management system published by SMEWebify. The HR Expense module’s scan_file parameter allows any self-registered user to upload arbitrary PHP files to a web-accessible directory, which can be executed to achieve remote code execution. Because the application ships with open self-registration and broken role-based access middleware, the vulnerability is effectively exploitable by unauthenticated remote attackers on default installations, and it carries a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Root cause: The HR Expense upload handler in HumanResourcesController.php (around lines 317–321) moves files submitted via the scan_file parameter into the web-accessible directory public/file/Expense/ using the original filename, without server-side MIME-type validation or a file-extension allowlist. This preserves the .php extension of uploaded files.
  • Trigger conditions: WebErpMesv2 allows open, unauthenticated self-registration, and its role-based access middleware does not correctly restrict access to the HR Expense functionality. This combination means an attacker does not need legitimate, pre-provisioned credentials to reach the vulnerable upload endpoint.
  • Attack vector: Network — an attacker self-registers an account (or otherwise reaches the endpoint due to the middleware flaw), uploads a PHP file disguised with an image content-type through the HR Expense scan_file parameter, and then requests the stored file at its predictable web-accessible path to trigger PHP code execution.
  • Impact: Full remote code execution on the underlying server, with complete loss of confidentiality, integrity, and availability of the host and any data it processes (CIA all rated High).

Affected software

  • Vendor: SMEWebify
  • Product: WebErpMesv2
  • Affected versions: 1.19 and earlier (advisory data also cites version 1.18 and earlier as vulnerable; no version is confirmed as officially patched at time of publication)

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: No officially confirmed patched release has been documented for this advisory; organizations running WebErpMesv2 1.19 or earlier should apply the fix referenced in commit 5c54862fa044b363fd2be03d586750e81afd6818 in the SMEWebify/WebErpMesv2 repository, or upgrade to the earliest available release that incorporates this fix once published.
  • If no patch is available/applied, implement the following workarounds:
    • Disable or restrict open user self-registration until the fix is deployed.
    • Enforce a strict server-side file-extension allowlist (e.g., jpg, jpeg, png, pdf) on the HR Expense upload feature, and validate MIME type server-side rather than trusting client-supplied headers.
    • Store uploaded files outside the web root, or serve them with randomized, non-executable filenames and disable script execution (e.g., PHP handlers) in the upload directory.
    • Audit and correct the role-based access middleware so that authorization failures deny access by default.
    • Restrict network exposure of the application (e.g., place it behind a VPN or IP allowlist) until remediation is confirmed, and monitor for unexpected files or requests under public/file/Expense/.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
