3.5.3
CVE-2021-4434 is a critical Remote Code Execution (RCE) vulnerability discovered in the Social Warfare plugin for WordPress. This vulnerability allows attackers to execute arbitrary code on a vulnerable server, potentially leading to complete system compromise. It affects versions of the plugin up to and including 3.5.2, with a fix available in version 3.5.3.
The impact of CVE-2021-4434 is severe. An attacker exploiting this vulnerability can execute arbitrary code on the web server hosting the WordPress site. This could involve gaining full control of the server, stealing sensitive data (user credentials, database information, website files), installing malware, or using the compromised server as a launchpad for further attacks against other systems. The ability to execute code directly on the server significantly expands the attack surface and potential damage.
CVE-2021-4434 was publicly disclosed on January 17, 2024. While no active exploitation campaigns have been definitively confirmed, the ease of exploitation and the critical nature of the vulnerability make it a high-priority target. Public proof-of-concept exploits are likely to emerge, increasing the risk of widespread exploitation. The vulnerability is not currently listed on CISA KEV.
Websites using the Social Warfare plugin, particularly those running older versions (≤3.5.3), are at significant risk. Shared hosting environments are especially vulnerable, as a compromise of one website can potentially impact others on the same server. Sites with limited security monitoring or outdated WordPress installations are also at higher risk.
