Official Description

Cross-site scripting (XSS) vulnerability in lanoba-social-plugin/index.php in the Lanoba Social plugin 1.0 for WordPress allows remote attackers to inject arbitrary web script or HTML via the action parameter.

Technical Analysis

CVE-2011-5182 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2011-5182. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
