The CVE-2014-4938 vulnerability represents a critical sql injection flaw in the WP Rss Poster plugin version 1.0.0 for WordPress platforms. This vulnerability specifically targets the administrative interface of the plugin, creating a pathway for remote attackers to execute malicious sql commands. The vulnerability manifests through the id parameter within the wrp-add-new page of the wp-admin/admin.php endpoint, which serves as the primary attack vector for exploitation.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the plugin's administrative code. When administrators navigate to the wrp-add-new page, the plugin fails to properly escape or validate the id parameter before incorporating it into sql queries. This allows attackers to inject malicious sql payloads that bypass normal security controls and directly manipulate the underlying database. The vulnerability operates at the application layer and specifically targets the wordpress administrative interface, making it particularly dangerous as it can be exploited by authenticated users with administrative privileges or potentially by unauthenticated attackers depending on the specific configuration.
From an operational impact perspective, this vulnerability creates severe consequences for wordpress installations using the affected plugin version. Successful exploitation enables attackers to execute arbitrary sql commands, potentially leading to complete database compromise, data exfiltration, or unauthorized modification of content. The vulnerability's remote exploitability means attackers can leverage it without requiring physical access to the server, making it particularly dangerous in multi-tenant hosting environments or managed wordpress installations. Attackers could potentially escalate privileges, gain persistent access, or use the compromised system as a foothold for further attacks within the network infrastructure.
Security professionals should note this vulnerability aligns with CWE-89, which specifically addresses sql injection weaknesses in software applications. The flaw also maps to several ATT&CK techniques including T1071.004 for application layer protocol communication and T1566 for credential access through social engineering or exploitation of web applications. Mitigation strategies should include immediate plugin updates to versions that address the sql injection vulnerability, implementation of web application firewalls to detect and block malicious sql injection attempts, and comprehensive input validation across all administrative interfaces. Additionally, organizations should conduct regular security audits of wordpress plugins, implement principle of least privilege for administrative accounts, and maintain up-to-date backup systems to ensure rapid recovery from potential compromise scenarios.
