The Download Manager plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 3.3.03. This vulnerability allows unauthenticated attackers to execute arbitrary shortcodes due to insufficient validation of user input before running do_shortcode. The potential impact of this vulnerability is significant, as it can lead to unauthorized access and manipulation of website content.
With a CVSS score of 7.3, this vulnerability is classified as high severity, indicating a serious risk to organizations utilizing the affected plugin. The ease of exploitation, combined with the potential consequences, necessitates immediate attention from security teams.
The urgency for defenders is critical. Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability and protect against potential exploitation.
As of now, there are no known exploits in the wild, but the lack of public proof of concept does not diminish the risk this vulnerability poses. Therefore, organizations must remain vigilant and proactive in their remediation efforts.
Vulnerability Details
The vulnerability in question is described as follows: The Download Manager plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 3.3.03. This is primarily due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode.
The vulnerability is classified under CWE-94, indicating improper control of generation of code ('Code Injection'). This flaw can have various impacts including confidentiality, integrity, and availability, all of which are rated as low.
The plugin is affected in its entirety, specifically the 'download_manager' component from vendor w3eden. The vulnerability was published on December 19, 2024.
Technical Analysis
The root cause of this vulnerability lies in the lack of proper input validation when executing shortcodes. Attackers may leverage this flaw to execute arbitrary PHP code on the server, which could lead to unauthorized actions being performed within the WordPress environment.
The attack vector is network-based, meaning an attacker could exploit this vulnerability remotely over the internet without needing physical access to the server. The attack complexity is low, as no special privileges are required for exploitation, and no user interaction is necessary.
Consequently, the confidentiality, integrity, and availability impacts are all rated as low, but the potential for an attack remains significant given the nature of the vulnerability.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data and the ability to manipulate website content without authentication. The potential blast radius for organizations using the affected plugin is considerable, as it could affect not only the individual website but also the reputation and trust of the organization.
Given the high CVSS score and the potential for exploitation, organizations should address this vulnerability in their priority patch cycle. The absence of known exploits does not mitigate the risk, as the vulnerability could still be targeted by threat actors.
