Summary

CVE-2025-1770 is a high-severity Path Traversal (CWE-22) vulnerability in Themewinter Eventin. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 35.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mitigates CVE-2025-1770 by identifying, prioritizing, and applying the vendor patch that corrects the improper 'style' parameter handling in the Eventin plugin.

SI-10 Information Input Validation good match

prevent

Requires validation of the 'style' parameter inputs to reject arbitrary file paths, preventing local file inclusion and subsequent PHP code execution.

AC-6 Least Privilege partial match

prevent

Enforces least privilege for Contributor-level users, limiting the scope and impact of exploitation even if the LFI is triggered.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1005 Data from Local System Collection

Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

attack.mitre.org →

T1059 Command and Scripting Interpreter Execution

Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

Why these techniques?

LFI in public-facing WordPress plugin directly enables T1190 for initial access/exploitation, T1005 for reading local files/sensitive data, and T1059 for executing PHP code on the server.

NVD Description

The Event Manager, Events Calendar, Tickets, Registrations – Eventin plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.0.24 via the 'style' parameter. This makes it possible for authenticated attackers, with Contributor-level access…

and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

Deeper analysisAI

CVE-2025-1770, published on 2025-03-20, is a Local File Inclusion (LFI) vulnerability (CWE-22) in the Event Manager, Events Calendar, Tickets, Registrations – Eventin plugin for WordPress. It affects all versions up to and including 4.0.24 and stems from improper handling of the 'style' parameter, which allows the inclusion and execution of arbitrary files on the server. The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

Authenticated attackers with Contributor-level access or higher can exploit this issue over the network with low complexity and no user interaction. By manipulating the 'style' parameter, they can include arbitrary files, execute PHP code within them, bypass access controls, obtain sensitive data, or achieve code execution, particularly if images or other "safe" file types containing PHP payloads can be uploaded and included.

Advisories and patches are detailed in the provided references, including Wordfence's threat intelligence report and WordPress plugin trac entries. Specific code locations in events-calendar.php (line 715) and tab-1.php (line 53) from version 4.0.24 are implicated, with changeset 3257023 indicating the applied fix.
