The vulnerability identified as CVE-2015-10090 represents a cross site scripting flaw within the Landing Pages Plugin version 1.8.7 and earlier. This security weakness resides in the plugin's handling of user input within an unspecified functionality component, creating a potential entry point for malicious actors to execute arbitrary code within the context of a victim's browser. The vulnerability's classification as remotely exploitable means that attackers can initiate attacks without requiring physical access to the target system or direct user interaction beyond visiting a malicious webpage.
The technical implementation of this XSS vulnerability stems from inadequate input validation and output sanitization within the plugin's codebase. When the Landing Pages Plugin processes user-supplied data through its affected functionality, it fails to properly escape or encode special characters that could be interpreted as HTML or JavaScript code. This allows attackers to inject malicious scripts that execute in the browser context of authenticated users, potentially leading to session hijacking, data theft, or further exploitation of the compromised system. The vulnerability aligns with CWE-79, which specifically addresses cross site scripting flaws in software applications, and follows the ATT&CK technique T1059.007 for script-based execution.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to perform various malicious activities including credential theft, defacement of landing pages, or redirection to malicious sites. Since the vulnerability affects a plugin that likely handles user-generated content or form submissions, attackers could exploit it to target administrators or regular users who visit compromised landing pages. The remote exploitability aspect means that threat actors can leverage this vulnerability through web-based attack vectors without requiring direct system access, making it particularly dangerous in environments where multiple users interact with the affected WordPress installation.
Security remediation for this vulnerability requires immediate upgrading to version 1.8.8 of the Landing Pages Plugin, which incorporates the patch identified by the commit hash c8e22c1340c11fedfb0a0a67ea690421bdb62b94. This upgrade addresses the underlying input validation issues by implementing proper sanitization and escaping mechanisms for user-supplied data. Organizations should also conduct thorough vulnerability assessments to identify any other potentially affected plugins or components within their WordPress environments, as similar vulnerabilities may exist in other third-party software. Additionally, implementing web application firewalls and content security policies can provide additional layers of protection against similar XSS attack vectors. The vulnerability serves as a reminder of the critical importance of keeping all WordPress plugins and themes updated to prevent exploitation of known security flaws.
