Atomic Edge analysis of CVE-2024-10938 (metadata-based):
This vulnerability is an instance of embedded malicious code (CWE-506). The OVRI Payment plugin version 1.7.0 contained one or more .htaccess files with malicious directives. These directives are designed to block the execution of legitimate scripts while explicitly allowing the execution of known malicious PHP files. The vulnerability description indicates the files are within the plugin’s directory. The risk arises if these files are moved to a higher-level directory, such as the site root, where they could affect the entire website’s behavior. The root cause is the intentional inclusion of harmful configuration files within the plugin’s distribution package. The exploitation method does not involve a remote attacker triggering a flaw. Instead, exploitation is contingent on the site administrator or a separate vulnerability moving the malicious .htaccess file. The impact is the disruption of normal site function and the potential execution of unauthorized PHP scripts, leading to integrity and availability loss. A fix requires the plugin author to release a clean version that removes the malicious files. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L) confirms network accessibility, low attack complexity, no privileges required, no user interaction, and impacts integrity and availability.
