Official Description

The WP User Frontend WordPress plugin before 3.5.26 does not validate and escape the status parameter before using it in a SQL statement in the Subscribers dashboard, leading to an SQL injection. Due to the lack of sanitisation and escaping, this could also lead to Reflected Cross-Site Scripting

Risk Analysis

The WP User Frontend WordPress plugin is vulnerable to SQL injection and Reflected Cross-Site Scripting (XSS) due to improper validation and escaping of the 'status' parameter. This could allow attackers to manipulate SQL statements or inject malicious scripts. As this is in CISA's KEV, it is actively exploited and poses a significant risk.

This vulnerability is actively exploited in the wild. The lack of sanitization and escaping makes it easily exploitable for both SQL injection and XSS.

Recommended Action

Update the WP User Frontend WordPress plugin to version 3.5.26 or later. Employ web application firewalls (WAFs) and ensure proper input validation and output encoding for all user-supplied data.

Technical Analysis

CVE-2021-25076 requires local access, meaning attackers must already have a foothold on the target system.

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

CISA has added CVE-2021-25076 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
