CVE-2024-33636

Vulnerability

Analysis CVE-2024-33636 is a missing authorization vulnerability in the WP Page Post Widget Clone plugin for WordPress, affecting all versions up to and including 1.0.1. The root cause is a broken access control issue, where the plugin fails to properly check user permissions or nonce tokens before executing certain higher-privileged actions [1].

Exploitation

An attacker can exploit this vulnerability without authentication by sending crafted requests to the vulnerable endpoint. No special privileges or network access beyond standard web connectivity is required. The vulnerability is particularly dangerous because it is actively used in mass-exploit campaigns targeting thousands of websites indiscriminately, regardless of their traffic size or popularity [1].

Impact

Successful exploitation allows an unprivileged user to perform actions that should require higher privileges, effectively leading to privilege escalation within the WordPress context. This could include modifying page or post clones, altering site content, or other unintended administrative actions, depending on the missing authorization checks [1].

Mitigation

The plugin vendor has not released an update, so immediate action is to update the plugin if a patched version becomes available. If updating is not possible, users should contact their hosting provider or web developer for alternative security measures, such as disabling the plugin or applying a Web Application Firewall (WAF) rule [1].
